concrete house | AiDomes

The following information covers Tiny Home Kit reg & sale pricing w’ specs.  Ai has added two new tiny home sizes to its Tiny Home assortment – 15′ and 18′!   These Tiny Dome Home Kits are constructed using Ai’s superior prefabricated insulated concrete panel system.  Consider them for Special Hideaway, vacation cabin, mother’s home, guest house, hunting cabin, glambing, tiny home, micro home, cottages for resort, rental units for veterans or a starter home.  The Ai dome is much stronger, has noncombustible materials in its wall panels, fire resistant concrete exterior & more insulated than a framed house, concrete block house, log cabin, tent or yurt.  Also all the panel materials contain no food source for mold growth.

Additional dome kits can be added later and linked to the first dome built on your site.  If you believe you want to add on later, discuss with our design team and a link can be installed on the first dome where a second dome can be connected later.

Tiny Dome Home Kits when assembled and finished can result in 172 sq.ft. to 1,278 sq.ft.  The domes can be one story. Dome sizes are measured by feet in diameter with the 15′, 18′, and 22′ kits having a first floor with optional attic/loft.  The 27′, 30′ & 34′ can have a second floor installed if you so desire. The 27′  dome second floor panels are large enough for a window dormer to accept fire egress size window.  The 34′ second floor window dormer is too small to accept a fire egress window so door dormer panels are installed above a first floor standard entryway to accept a fire egress size casement window.  With a 2nd floor egress window installed this allows the 27′ & 34′ domes second floor to contain a bedroom; resulting in the 27’ & 34’ domes being two bedroom/two bath size homes. The 30′ dome second floor panels are not large enough for a window dormer so no bedroom can be designed – use the 30′ second floor for storage, office, craft area, additional bathroom, rec room.  To view stock plans for the 15′ and 18′ along with plans for the other Tiny Domes, click on Tiny Home Plans.

22′ Tiny Dome Home After Building Kit Assembled & Finished.

As far as Tiny Homes meeting minimum size house requirements – in some areas,  groups are petitioning their county or their city elected government officials to allow them to have Tiny Home Communities (called pocket neighborhoods) where the minimum house size can be below state code. The City of Rockledge, Florida agreed that a group whose face book page is called Rockledge Tiny House Community can purchase property and build Tiny Homes from 172 sq. ft up to 1000 sq ft. in their city.   Normally in Florida the minimum new house size requirement is 500 sq.ft. or 800 sq.ft. or 1,000 sq.ft.  So congratulations to the City of Rockledge Tiny House Group for its victory in changing minimum size house requirements in their city to as small as 172 sq.ft..

Please check local codes to see how Tiny Homes can be built for cottages in a resort or for rental units to rent out to migrant workers, veterans and individuals wanting to live in strong (225 mph & F4 tornado warranty), energy efficient houses whose exterior concrete is fire resistant.  To view comparison of concrete dome kit to log cabin, click on log cabin.  To view info on Ai dome and tree impact & snow load, click on Tree.   To view complete summary of advantages of Ai dome, click on Summary.

Tiny Dome Building Kit Contents:

  1. 15’ & 18’ Kits consist of all the triangle prefab panels and standard 4’ risers plus 2’ riser prefab component panels for the dome shell and panels for one entryway. The kit can be purchased with 7″ EPS, 1/2″ Drywall & exterior 3/4″ concrete reinforced with galvanized steel mesh/fibers.  And only the 15′ & 18′ kits can be purchased with 3 1/2″ EPS, no drywall and no reinforced concrete.  The larger kits cannot be purchased with only 3 1/2″ EPS because this size insulation makes the larger panels to flexible causing EPS breakage.
  2. 22’ & 27’ Kits  consists of all the triangle prefab panels and standard 4’ riser prefab component panels for the dome shell and panels for one entryway.  5 foot tall risers can be ordered instead of the standard four foot tall risers. Your floor plan selection determines how many more entryways and dormers are in your kit.
  3. 30’ & 34’ Kits consist of all the triangle prefab panels and standard 4’ risers prefab component panels for the dome shell and panels for one entryway. To increase first floor ceiling height where a second floor is above, on site install a one foot tall or two foot tall perimeter wall to increase the height to 8’6″ or 9’6″.  Your floor plan selection determines how many more entryways and dormers are in your kit.

Each triangle and riser prefab component panel consists of exterior ¾” fiber concrete reinforced with galvanized steel mesh, center core of 7″ R-28 expanded polystyrene (EPS) insulation with interior special moisture resistant, mold resistant 1/2″ gypsum drywall from Georgia Pacific called DensArmor Plus. During kit assembly it can rain. Water does not harm this special DensArmor drywall. The 15′ & 18′ kits can be purchased with 3 1/2″ R14 EPS insulation and no drywall. 

The dome kit’s prefab concrete panels can be assembled by owner builders and is a true Do It Yourself kit. All the panels come marked with numbers and letters to match the building plans and the Assembly Manual. On site,  fiber concrete is troweled into seams between the panels and on the entryways or dormers. Seam concrete average thickness averages two inches. An Independent Kit Assembly Consultant can be hired to supervise your workers or your Builder’s workers during kit assembly.

To view samples of floor plan layouts, click on Stock Plans. If you do not see a stock plan to fit your desires, Ai can modify or customize a plan from your sketches and descriptions.  Each Set of Building Plans includes the floor plan layout(s) and consists of 13 – 17 blueprints depending on type of entryways and dormers in your kit.  To view sale pricing on all the stock plans and the dome building kit for each plan, click on Stock Plans & Kit Sale Prices.

Ai’s philosophy is that each Buyer pays for only what they need.  Ai does not burden the price of the building kit with plan’s pricing, engineer seal cost or energy report cost. Building plans are purchased three months to -1 1/2 years prior to kit shipment.  About 50% of the building departments require engineer sealed plans and an energy report to issue a permit. As a result, each customer pays for their plans separately from the building kit and pays for a seal and energy report only if their building department requires them.

Building Departments vary by state as to what they require to issue a new home building permit.  If you give Ai your parcel ID number & building department name, we will call and email info to them and find out what is required for them to issue a permit.  Will they require the building plans to be sealed and stamped by an engineer licensed for your state? Will they require an Energy Report?  If required these items can be purchased from American Ingenuity. To learn more about building permit, click on permit.

The standard foundation under Ai’s domes is a concrete slab. Other types of foundations; i.e. basements, stem wall, pilings, require the hiring of an engineer. Call for engineer pricing. Each buyer tells Ai the type foundation they want designed.  The foundation type is determined by property terrain, building department requirements and requirements from a soil report.

Plans may be purchased with a credit card, check or money order. Stock plans utilize a concrete slab foundation and are delivered within 2-4 weeks, Allow at least 5 modified plans and 8-10-12 weeks for custom plans.

How does the American Ingenuity dome withstand tree impact & snow load versus truss roof house?  Very well based on two actual dome owner’s experiences.

Exterior basement snow 0272

For those of you who are researching what type house to build in a forested area, please consider the advantages of an American Ingenuity concrete dome versus a log home with a truss roof or a conventional house with a truss roof.

One of American Ingenuity’s perspective kit buyers emailed this question: “When I was living in the deep woods and any kind of wind storm or even a bad ice storm came up it was a major concern/fear of a large tree branch hitting the house.  How does the Ai steel reinforced concrete dome roof compare to truss roof for tree impact & heavy snow load?”    Based on two actual Ai dome home examples, the Ai concrete roof is so strong it can resist 30″ in diameter tree impact and the weight of several feet of snow. 

Homes built in a forested environment run the risk of having a tree fall on the roof or if in a cold climate a possible ice storm can cause ice loaded tree branches to fall on the roof. The steel reinforced concrete roof in an American Ingenuity dome is resistant to tree impact damage. However a wood truss roof is likely to be damaged from a tree branch or tree falling on the roof.

The strength of the Ai dome is evident in this example of a tree falling on the American Ingenuity dome. There was no damage to the Brack’s 48′ American Ingenuity dome after winds in excess of 75 mph hit North Carolina in July of 1996. The real test came when a 115′ high, 30″ in diameter hickory tree was blown over and fell on their dome. The impact broke a 10″ diameter branch off the tree. The tree slid off the dome and landed on a deck post driving it and it’s 16″ square concrete footer 6″ further into the ground. The insurance agent who inspected the damage to the deck conveyed his amazement about the dome’s strength with this comment, “If that had been a frame house the tree would have ended up in the basement!”

The American Ingenuity dome could handle the tree’s impact because the steel mesh from panel to panel is overlapped, locked & covered with fiber concrete. As a result the continuous mesh transfers the stress throughout the dome. In a conventional house the stress is confined to one area resulting in the tree probably damaging the roof or coming through the roof.

More about heavy snow loads: Mr. and Mrs. Carroll visited Robens and Tom Napolitan’s dome. Robens was enthusiastic, but Tom was not. Tom explained to the Carroll’s, “Its all HER idea, I didn’t want a dome.” Mary Carroll phoned the Napolitans during a cold spell where they experienced heavy snow fall. Mrs. Carroll said you couldn’t keep Tom quiet this time. He had nothing but wonderful things to say about the dome and had completely turned around about the wonders of living in an American Ingenuity dome…..“ROOFS HAD COLLAPSED in their area under several feet of snow, but NOT HIS DOME!” Tom’s turnaround sold Mary and her husband on an Ai dome.

How does the Ai prefab home dome stand up to high winds, ice storms, several feet of snow & forest fire?  American Ingenuity performed a load test on our largest 48′ triangle.  The triangle shaped component panel withstood 170 lbs. per sq. ft.  load.  A 120-mph wind will exert a pressure of 30 lbs. per sq. ft. on a vertical wall and a snow load exceeding 90 lbs. per sq. ft. is rare. Typically snow loads are 20 to 50lbs. per sq.ft.

The strength of the concrete Ai dome makes it resistant against tree impact, heavy snows and fires making it ideal to build for a vacation home or a retirement home where the home is not occupied year round. If the dome home is built in a cold climate, there will be times when the family may want to live in a warmer climate during the winter. As a result the home owner wants to build as resistant a home they can against heavy snow load or tree impact or fire.   For info about fire and Ai dome, click on  forest fire.

Greater Exterior Wall & Roof Strength – the concrete American Ingenuity dome exterior comes with 225 mph wind and F4 tornado warranty. An Ai dome went thru a tornado & Hurricane Andrew at the same time with no structural damage. An Ai dome went through Hurricane Katrina with no structural damage.

When deciding which building kit to purchase, please compare apples to apples which means please compare the contents of the log home kit or the traditional home kit vs the contents of the Ai dome kit and compare kit costs. The Ai panelized system has proven to save our client’s labor time, as well as a reduction in material waste and material costs vs a log home kit while having numerous advantages over log cabin home —- fire resistant concrete exterior, tree impact resistance, able to handle heavy snow load.  For log home kit comparison to the Ai dome, click on Log Cabin Home.

The process of overlapping/locking the steel mesh of American Ingenuity’s prefabricated panels to adjacent panels and filling the seams with special fiber concrete produces 1) the structural components of the home; 2) the finished concrete exterior surface; 3)all the shell R28 insulation is installed; and 4) all the dome shell 1/2″ drywall is installed. There is no need for material costs and labor costs to install roofing plywood, tar paper, shingles or interior attic & wall insulation and shell drywall (or wood panels).  To view photos of Kit Assembly, click on Assembly.

The American Ingenuity dome is very energy efficient because it has 30% less surface area than a conventional house and has thick EPS insulation that is not interrupted by wood…expect heating and cooling bills to be 50% to 60% than your neighbors.  Ai’s standard 7″ Expanded polystyrene insulation is comparable to 11″ of fiber glass batting.  Here are some quotes about Ai dome and energy efficiency:

As far as functioning in cold, snowy environment, American Ingenuity domes have been built in Canada, one built at 7,500 feet elevation in Utah and Aidomes have been built in all cold states in the USA except for New Hampshire, Rhode Island and North Dakota.

One of our customers in Pennsylvania built a 40′ dome on full basement. This is quote from them: ““We live in the mountains of PA. The winters up here can be brutal. Our Ai Dome is a 40ft with Link on a 9″ thick livable basement. {Den, Office/Computer room, Kitchenette} The entire interior, to include the mechanical room, is heated and cooled by a GeoThermal, Water furnace, Radiant floor system. Our zone controllers are set on 74 degrees winter and summer. Our sole power source, at present, is the grid. Our costs per month range from $99 to a high of $120. We were amazed that our cost now are less than when we lived in a 14 by 73 ft mobile home while building the Dome. Our decision to build an American Ingenuity Dome home was the best decision we have ever made.” To view pictures of their dome and other info, click on Charles Dome.

A picture of the dome at 7,500 feet elevation in Utah showing snow is one of the flashing pictures on our home page. The dome is off the grid and has increased EPS insulation from our standard 7″ R28 to 9″ or R36. Quote from the Utah dome owners: “Our house and solar electric system have met and exceeded all of our expectations. Our home is warm and spacious. Even with nighttime temperatures below zero, a fire in the masonry heater in the evening and a full day of sun warms the house to 70 degrees F. Our average summertime power consumption is between 150 and 200 kWh/month for 2700 square feet of living space. Wintertime consumption is somewhat higher. For comparison, our average pre-solar usage was near 600 kWh/month in our prior 2000 square foot suburban home.”  To view pictures and other info about the dome at 7,500 feet elevation, click on Collar Domes.

The Aidomes are even more energy efficient when heating is required instead of cooling. When cooling, kilowatts have to be used to overcome heat from clothes dryer, dishwasher, sun light, etc. When heating those heat sources are used.  Ai’s 3,700 sq.ft. office domes can be cooled for less than $55 a  month in the hot Florida summer months.  A Florida 1,200 sq.ft. 34′ dome can be cooled for less than $22 a month in the hot Florida summer months.

 

 

Ai received the following question about the fire resistance details for an American Ingenuity concrete dome versus a Monolithic concrete dome.  The question from Greg Legg is in regards to the YouTube Video posted below about a fire and concrete domes.  “I’m looking at the differences between your domes and the monolithic dome in the video about a fast moving fire and wondering how important it is to water down the exterior if a fire is approaching. In the video the owner mentions that he was surprised the pvc exterior wasn’t damaged during the fire. Not sure what he meant by pvc exterior but made me wonder.

A house roof on fire and smoke.

I live in an area where the only water source is water wells using an electric pumps for pressure. During fires it’s very easy to lose power from downed lines. If that was to happen there is no way I could hose down the exterior of the house. How would your exterior be any different in this situation?” Greg Legg

The American Ingenuity (Ai) dome is designed to be as safe and fireproof as possible, the dome exterior is entirely noncombustible concrete. The Ai dome exterior is fire resistant concrete reinforced with galvanized steel mesh that does not require watering down as the homeowner did for the PVC covering on the Monolithic Dome. 

On site during the Ai dome panel assembly, the exterior seam areas between the prefab concreted panels consist of overlapped locked steel mesh filled with fiber concrete. The Ai dome shell is built by installing Ai’s prefabricated concreted panels onto a temporary wooden rib system.  After all the seam areas, entryways and dormers are concreted, the dome is self supporting and the temporary wooden system is removed.  The exterior concrete is primed and painted. There is no wood in or on the Ai dome shell to burn or to interrupt the insulation. There are no shingles to burn.The exterior concrete on the American Ingenuity Dome has no exposed PVC membrane or exterior material that needs to be watered down.

Monolithic Dome Assembly per their website:  In the monolithic dome assembly an Air Form is inflated, polyurethane foam is applied to the interior surface of the Airform, steel reinforcing rebar is attached to the foam using a specially engineered layout of hoop (horizontal) and vertical steel rebar and then Shotcrete – a special spray mix of concrete – is applied to the interior surface of the dome. The steel rebar is embedded in the concrete and then about three inches of shotcrete is applied.  This method results in an exposed exterior PVC membrane or exterior material which was watered down in the dome video.

All the panels in the American Ingenuity dome kit come to your job site premarked with numbers and letters to match the Nomenclature blueprint in the Building Plans.  An Assembly Manual is shipped with each Ai dome kit.  The kit is assembled by the owner builder or the owner hires a builder.  If desired a Kit Assembly Consultant can be hired to supervise the workers during kit assembly.  The process of stacking the panels, overlapping/locking the steel mesh of adjacent panels and filling the seams with special fiber concrete, produces the structural components of the home, the finished concrete surface, installs the R28 insulation and all the dome shell 1/2″ drywall.

What are the American Ingenuity triangular and rectangular shaped prefab panels made from? Center core of 7″ Expanded Polystyrene R-28 Insulation (not Styrofoam!), exterior is ¾” thick concrete reinforced with galvanized steel mesh with interior of 1/2″ Georgia-Pacific DensArmor Plus High-Performance gypsum drywall board (which is moisture resistant, mold resistant gypsum and noncombustible).

After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand trowelled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.

  3. The Florida 22′ dome was built for a 349 sq.ft. work shop.

American Ingenuity’s Tiny Dome Kit assortment consists of six kit sizes measured in diameter by feet: 15′, 18′, 22′, 27′, 30′ & 34′.  These domes have square footage from 172 to 1,278.   Below are stock plans for the 15′ – 34′ domes and pictures of a 34′ dome home with other info.  To view regular and sale pricing with specifications on the 15′, 18′, 22′, 27′, 30′ & 34 click on Tiny Dome

  1. 15′ – 172 sq.ft. – one bedroom one bath size – one floor with optional attic/loft.
  2. 18′ – 249 sq.ft. – one bedroom one bath size – one floor with optional attic/loft.
  3. 22′ – 370 sq.ft. – one bedroom one bath size – one floor with optional attic/loft.
  4. 27′ – 786 sq.ft. – two bedrooms two bath size – two floors. Two frequency geometry that allows for 2nd floor egress window.
  5. 30′ – 1,089 sq.ft. – one bedroom one bath size on first floor. No egress window on second floor (3 freq)…use second floor for storage, office, work shop, additional bathroom or craft area.
  6. 34′ – up to 1,100 – 1,278 sq.ft. – two bedroom two bath size – two floors.  Second floor window dormer panels will not accept fire egress size window. As a result  a second floor door dormer is installed above above a first floor standard entryway to frame in egress window.

As far as Tiny Homes meeting minimum size house requirements – in some areas groups are petitioning their county or their city governing bodies to allow them to have Tiny Home Communities (called pocket neighborhoods) where the minimum house size can be below state code. The City of Rockledge Florida agreed that a group whose face book page is called Rockledge Tiny House Community can purchase property and build Tiny Homes from 172 sq. ft up to 1000 sq ft. in their city.   Normally in Florida the minimum new house size requirement is 500 sq.ft. or 800 sq.ft. or 1,000 sq.ft.  So congratulations to the City of Rockledge Tiny House Group for its victory in changing minimum size house requirements in their city to 172 sq.ft.

Have you dreamed about living in a super-Green, super strong home? Would you like good living in small spaces? American Ingenuity has the solution for you.  Choose from six sizes: 15′, 18′, 22′, 27′, 30′ or 34′ tiny domes. Or utilize the 15′-34′ domes to build a small vacation home, glambing dome, get-a-way or work shop dome. Can’t envision living in such a tiny home, view Ikea YouTube to see video filmed by an Ikea customer in Ikea store.
The 22′ dome can also be a built as a one car garage dome.   The 27′ dome can be built as a two small to medium car garage.  This link has garage dome info.22' Exterior solar Pineapple garage

 22′ dome utilized as one car garage linked to 34′ – 1,075 sq.ft. dome home

Each prefab panel’s core is 7″ EPS (expanded polystyrene) R-28 insulation precisely angle cut to form the geodesic shape.   Applied to the outside is pre-finished three quarters inch concrete, reinforced with galvanized steel mesh and fibers.  Applied to the interior is half inch Georgia Pacific DensArmor gypsum wallboard….gypsum’s facing is fiberglass instead of paper.  Wallboard is moisture resistant and mold resistant. No wood in or on the shell to rot or for termites to eat or to burn.  No shingles to blow off in high winds.  On site after the kit is assembled, the exterior concrete is primed and painted with paint. The 15′ and 18′ dome kits can be purchased with 3 1/2″ R14 EPS, no interior 1/2″ drywall & no steel reinforced concrete exterior.  Larger domes cannot be purchased this way because the larger size panels cause the EPS to be flexible and break.

The kit assembly begins after the foundation and floor are completed and a temporary wooden rib system is assembled in the geodesic shape.  The assembly process consists of stacking the panels on the rib system overlapping and locking the steel mesh of adjacent panels, filling the seams with special formulated concrete and concreting of the entryways and dormers.  Finish the interior wall board seams with tape and joint compound.  This process produces the structural components, completes the finished exterior surface, installs the insulation and all the interior shell wallboard.  To view a video on the 22′ Assembly, view Special Hideaway.  To view pictures showing general panel assembly, view Dome Kit Assembly.

On site, under the entryways and dormers a 2×4 or 2×6 wall is framed in to install your locally purchased doors and windows.

The concrete applied in the seams and on the entryways and dormers is sponge finished to match the pre-finished texture of the concrete panels. The dome is primed with concrete primer and then painted with two coats of exterior concrete paint to achieve the color you desire.

All panels are premarked with numbers and letters to match the building plans and the Assembly Manual. The most successful dome kit assemblies result when the home owner hires the independent Kit Assembly Consultant to supervise the temporary rib system assembly & the kit assembly. If your budget is tight consider hiring the Consultant for a minimum of three days to supervise the rib system assembly, concrete mixing and first row of panel assembly…..just to get you started.  If you desire to hire a builder, he or she can hire the Assembly Specialist to supervise their workers to get the dome kit assembled with the first layer of concrete in the seams and on the entryways and dormers.  To view Ai’s web site file about the independent Specialist, view Specialist.

Prior to assembly of the dome kit, a temporary wooden rib system is assembled using your own 2×4’s cut to specific lengths (or purchase the cut, drilled, painted 2×4’s from Ai), bolts/nuts/washers purchased from Ai  and steel hubs borrowed from American Ingenuity by placing a $455 deposit.  This deposit covers a 5 month rental period ($20 a month thereafter).  Once the dome kit is assembled, the rib system is removed with the client mailing or UPSing the hubs back to Ai to receive a deposit refund.  Triangle Panels weight 155 to 180 lbs. Risers weight 255 lbs.  During assembly the panels are placed with some type of hoisting mechanism.  Lifting spikes are purchased from Ai.  To view American Ingenuity’s web site file that explains the rib system, view Support System. If importing the kit out of the USA, buyer purchases the steel hubs from Ai.

Please check with your building department, some have minimum house square footage requirements .  If the 15′, or 18′ or 22′ dome may not meet their requirements. Ai manufactures a 27′ in diameter dome that can have 555 sq.ft. on the first floor and 225 sq.ft. on the second floor for a total of 780 sq.ft.  To view Ai’s web page that lists the dome sizes with their square footages, view Dome Sizes.

Please contact your building department and ask:

  • If there is a minimum size new house requirement?
  • Do they require a garage to be built with the house?  If so is there a minimum size garage requirement?
  • What do they require to issue a building permit?  Do they require engineer sealed plans and an Energy Report?  If so, those items can be purchased through American Ingenuity. The Energy Report has evolved into a very specific and technical report that requires Ai to have specific window and exterior door info (frame type, double pane or impact resistant glass), Low E number, U factor, SHGC number to fill out the Energy Report.  This means the dome buyer will shop for their exterior doors and windows and provide detailed spec sheets to Ai about each door and window, their water heater and AC/furnace.

Payments: American Ingenuity kits are not stocked and are manufactured on a custom order basis and are considered a Specialized Order, made exclusively for the customer requesting it.  These Specialized Orders require a 30% to 40%  deposit, signed Order Form, Conditions of Sale and Specialized Material Agreement. Once Ai receives these items, materials will be purchased and manufacturing started to meet your shipment date. If you cancel your order after signing the Specialized Agreement 30% deposit on each kit is non-refundable and your rights to the kit(s) are forfeited.  The balance, in the form of a cashier’s check or bank check including USA shipping costs (made out to American Ingenuity) is due 21 days prior to shipment. Florida residents, add sales tax plus your counties’ surtax.  Credit Cards are not accepted on the building kit. If the building kit is shipped out of Florida, no Florida sales tax or surtax is paid. If kits are exported, buyer pays freight forwarder directly for inland trucking costs and ocean shipping costs.

Delivery and Availability:  Once Ai receives your 30% or 40% deposit (deposit amount depends on kit size) based on your Building Kit with options pricing and signed Building Kit Order Form, Conditions of Sale and Specialized Material Agreement, American Ingenuity schedules your kit for manufacturing. Depending on the time of year and size of dome, allow four to six to twelve weeks for manufacturing time.

SHIPPING: If your site is in the continental USA, American Ingenuity can arrange shipping on 53’ step deck semi-truck. Freight varies from $2.70 to $2.90 per mile ($800 minimum) per truck, from American Ingenuity plant in Rockledge, Florida. One truck can carry five 15’ kits; or two 18’ kits; or two 22’ kits; or one 22’ kit & one 27’ kit; or one 30′ kit; or one 34′ kit – each with 7” EPS insulation.

15′ & 18′ Kit:  If 3 ½” EPS and no drywall one truck can carry up to ten 15’ kits; or up to four 18’ kits. 22’, 27′, 30′ and 34′ kits cannot be purchased with 3 ½” EPS. The panels are too large in these larger kits to manufacture with thinner 3 1/2″ insulation. The 7″ insulation is required so the panel is not flexible during movement.

For international shipping the following is the number of 15′ and 18′ kits that can fit in one 45′ high cube container. To learn about importing, click on importing.  2×4 ribs refers to 2×4’s that are cut, drilled & painted to specific specs for the temporary support system described above.

Four 15′ kits with 7″ EPS, 1/2″ drywall, standard 4′ risers & 2′ risers & two sets of 2×4 ribs.
Eight 15′ kits with 3 1/2″ EPS, no drywall, standard 4′ risers & 2′ risers & two sets of 2×4 ribs.

Two 18′ kits with 7″ EPS, 1/2″ drywall, standard 4′ risers & 2′ risers & one set of 2×4 ribs.
Four 18′ kits with 3 1/2″ EPS, no drywall, standard 4′ risers & 2′ risers & one set of 2×4 ribs.

The number of kits that can fit on one truck or in one container can change if the building kit contains maxed out entryways, dormers, link and thicker insulation. For example, a 48′ kit with 9″ EPS cannot fit on one semi-truck.  Entryways and a link take up more space than triangular and riser panels.  Once you select your floor plan, Ai can be specific about how many truck(s) or containers your order will take. Each International client hires a freight forwarder to coordinate their container’s shipping and pays their shipping and custom fees directly to the freight forwarder.

Ai’s manufacturing costs in Florida are well below the national average, which offsets any long distance shipping expenses. Ai can actually manufacture a kit here in Florida and ship to western states – Washington, California, Nevada, Oregon, Utah, Arizona, etc. cheaper than we could manufacture it there. Having our manufacturing plant located in Florida is advantageous for shipping since more is shipped in than out of the state, leaving many trucks headed out empty.

Ai utilizes independent trucking agencies. American Ingenuity contracts to have these trucks carry your building kit outside Florida for approximately $2.50  to $2.90 per mile per truck from Ai’s plant in Rockledge, Florida. Shipping within Florida is a minimum of $800. If your Florida building site is south of our factory, the truckers charge more because they have to drive south before they can drive north to leave Florida.  These trucking costs are less than Ai could do with our own trucks because if we used our own trucks, they would have to deliver the kit and return to our factory empty.

Per mile shipping costs can vary due to fuel costs and travel distances. View Shipping to learn more.

American Ingenuity’s Philosophy:

One of the main reasons American Ingenuity is very reputable is that we really try to treat all our customers the same. Our business philosophy and product is unique to the housing industry. Ai believes that each client should pay for only what they need.

  • Each person who wants to research our building kit further can do so by purchasing the Planning Kit with DVD or purchase the DVD separately.
  • None of Ai’s staff is on commission.
  • About 40% of Ai’s clients do not need engineer sealed building plans, or Energy Report or Structural Calculations in order to obtain a building permit. As a result the seal, energy report and calculations are separate costs and paid only by those whose building departments require them.

As a result of the above philosophy, the American Ingenuity dome shell kit costs about one third to one half less than the shell materials cost for a conventional house or wooden dome or sprayed concrete dome.

The information below is in reference to a specific 22′ floor plan named Eco Custom Cottage.

This is a 22 foot in diameter dome kit, which Ai has customized. Please call for pricing. This custom 22’ in diameter dome when finished has a first floor living space of 371 sq. ft. with an optional attic of 127 sq. ft. Ai has raised the riser wall height from four feet to five feet.  The additional one foot in height increases the attic square footage to 127 sq. ft., which is an additional 46 sq. ft. over the basic 22’ dome building kit.  The exterior of each triangle & riser panel is steel reinforced concrete.   The middle of the panel is 7″ EPS insulation (R-28) with 1/2″ Georgia Pacific DensArmor Gypsum drywall adhered to the underside of the EPS with wallboard adhesive.  Ai has based the pricing for this kit upon Ai selecting the week/day of shipment during the month agreed upon by Buyer & Ai.

Building a Concrete Home – Panel Composition.  Because of fires, super storms, hurricanes and tornadoes, home owners are researching concrete home construction and finding the American Ingenuity concrete dome kit. Building an Ai dome from prefabricated concrete panels makes home construction easier and results in the dome exterior having a 225 mph wind and F4 tornado guarantee. The process of stacking the panels, overlapping/locking the steel mesh of adjacent panels and filling the seams with special fiber concrete, produces the structural components of the home, the finished concrete surface, installs the insulation and all the dome shell 1/2″ drywall.    To learn about Building Kit Assembly click on Assembly.  An Expanded Assembly Manual is now available with each dome kit order.

How long does it take to assemble the dome kit if I use the Kit Assembly Specialist? Depending on the size dome, and if your building kit has two entryways and four dormers with dome built on concrete slab, the shell assembly with one layer of concrete in the panel seams and on the entryways and dormers can take about 9 to 16 days. Assembly time depends on the number of workers in your team, your foundation type, weather and the type of hoisting mechanism. Click on Kit Assembly Specialist to learn more.

Side of view of panel being installed. The panel exterior is 3/4″ concrete reinforced with galvanized steel mesh. After the mesh is overlapped and locked between panels, on site special fiber concrete is mixed and hand trowelled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.

Concrete Home
Exterior Dome Panels Have No Wood To Burn or To Rot or For Termites To Eat
No Shingles or Roof to blow off in high winds

To support the panels during dome kit assembly, a temporary wooden rib system is installed. Once all the seams are concreted and the entryways and dormers are concreted, the dome is self supporting and the wooden rib system is removed. Most of the wood can be recycled as interior framing.

In this view of dome kit being assembled a side view of a component panel can be seen. The panel exterior is 3/4″ concrete reinforced with fibers & galvanized steel mesh. After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand troweled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas average of 2″ thick concrete.

What are the American Ingenuity triangular and rectangular shaped panels made from? Center core of 7″ Expanded Polystyrene R-28 Insulation (not Styrofoam!), exterior is ¾” thick concrete reinforced with fibers & galvanized steel mesh with interior of 1/2″ Georgia-Pacific DensArmor Plus High-Performance gypsum drywall board (which is moisture resistant, mold resistant gypsum and noncombustible).  None of the materials in the panel are combustible or contain a food source for mold growth.

Superior Insulating Technology The core of each panel consists of a seven inch block of R-28 rigid modified expanded polystyrene (E.P.S.) insulation. The E.P.S. Insulation that Ai utilizes contains NO HBCD, NO TCPP, NO CFCs and NO formaldehyde and is not Styrofoam.   The EPS that Ai utilizes has a flame retardant added to it, therefore the EPS is noncombustible and is protected by the 1/2″ DensArmor wallboard which is non-combustible and provides the Code required 15 minute thermal barrier.   The EPS that Ai utilizes does not out gas poisonous chemicals.

Your American Ingenuity concrete home kit is affordable and strong because it is engineered as a system of prefinished component panels. Each panel is cut at a computer-generated angle so that it fits flush with the adjacent panel. The edges are precisely beveled at the seams where steel mesh and concrete will unite to complete the structure.

Q: Do you have an engineering statement about your dome panels that can be reviewed?

A:  Yes, to view the statement click on Engineering.

After the foundation is installed, the dome shell assembly consists of:

  • Erecting a temporary wooden rib system with supports under each hub.
  • Using some type of hoisting mechanism place the component panels one row at a time upon the rib system.
  • Overlapping the steel mesh from adjacent panels. Locking the steel mesh with “C” rings and pliers. Depressing the mesh into the seams.
  • Installing rebar, cables, hardware, (headers, king studs for doors and windows)  and suspension rods in appropriate seams per the building plans.
  • Watering down prefab concrete in the areas where new concrete will be applied. Applying one layer of fiber concrete in the seams and on the entryway/dormer panels one row at a time. Depending upon the dome size, there are four to five rows of panels.
  • Once the last row is installed then the second layer of concrete is applied in the seams between the panels and on the entryways and dormers. Bonding agent is applied between the two layers.  Cured concrete in the seams and around the area where new concrete is being applied is watered down prior to bonding agent and new concrete being installed.  The new concrete is misted per the Assembly Manual.
  • Only the seam areas between the panels and the entryways/dormers/cupola/link are concreted. Do not concrete over the finished prefab concrete on each panel.
  • Finishing exterior framed walls and Installing your locally purchased doors and windows.
  • Removing the temporary wooden rib system. Most of the wood can be recycled into interior framing and second floor perimeter knee wall framing.
  • Watering down the concrete exterior 3-4 weeks to remove efflorescence prior to priming and painting the concrete exterior.
  • Hiring conventional subcontractors: framer, electrician, plumber, drywall finisher, cabinet installer, HVAC, etc. to finish the interior of the dome.
  • Priming and painting the exterior of the dome.
  • Finishing the seams between the interior shell wall board with joint compound, fiberglass tape and applying joint compound in a skip trowel method over all the shell drywall.  Ask Ai for latest interior shell finishing document.
  • Priming and painting the shell wallboard.

American Ingenuity’s Component Panel’s steel mesh, concrete, EPS insulation and DensArmor wallboard contain no food source for mold growth and are therefore mold resistant.  The Georgia Pacific wallboard is not conventional sheet rock. Conventional sheet rock consists of  conventional gypsum and paper backing.  Sheet rock when it gets wet crumbles and molds with the paper matting as a food source for mold growth.  The DensArmor gypsum when it gets wet does not crumble.  It has fiberglass backing on both sides is no food source for mold growth. 

Tell us more about American Ingenuity’s panel materials.

Concrete: The panel concrete is a special formulation containing synthetic fibers and liquid admixtures. Locally purchase bags of Portland cement and masonry sand.  After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand troweled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.  Prior to applying new concrete, water down all concrete around areas where work will be done. 

Mix the ingredients with a Mortar Mixer NOT a cement mixer!  Ai ships with your building kit the same fibers and admixtures that are used in the panel concrete so the seam concrete which is mixed on site will have the same properties as the panel concrete. These ingredients improve the concrete’s characteristics, create super toughness, extend durability, give higher tensile and compressive strength, provide elasticity for expansion and improve freeze protection.  The first layer of seam concrete contains two liquid admixtures and synthetic fibers.  The second layer does not require fibers; however now due to advances in fiber technology there are small 1/4″ fibers which can now be added to the second layer.  These smaller fibers for the second layer can be purchased from Ai.

The concrete in your concrete home out performs other exteriors because of its specially developed formula. Because of its exceptional composition, it actually gains strength over the years.

The exterior panel concrete, which is 3/4 inch thick, adheres directly to the steel mesh and E.P.S. insulation without the need of a bonding agent.  The panel concrete is hand applied, hand troweled, and hand sponged at American Ingenuity’s Rockledge Florida factory.  During the on site process of concreting the seams, entryways, dormers, etc., a bonding agent is applied on the first layer of concrete before the second layer is applied.  Bonding Agent is supplied with the kit with additional bonding agent being purchased from Ai. This bonding agent is not diluted onsite.  It is used full strength and must rest 30 minutes before new concrete can be applied over it.  Prior to applying bonding agent, water down cured concrete.  Before applying second layer of concrete, water down all cured concrete in the seams and around where the new concrete will be applied.  The final layer of concrete is sponge float finished on site.

Steel: Galvanized steel wire mesh is encased in the concrete of each component panel and extends out over the insulation’s beveled edges. As your dome panels are assembled, the mesh of each panel overlaps minimum 2″ and is hooked to that of the adjacent panels with C-rings (commonly called “hog rings”). The dome then becomes encircled by steel mesh.

E.P.S. Insulation that Ai utilizes contains NO HBCD, NO TCPP, NO CFCs, NO formaldehyde.  The EPS thickness is 7″ (R28).  The seven inches of sturdy, rigid, nontoxic R-28 expanded polystyrene (E.P.S.) insulation forms the core of each component panel. This is NOT Styrofoam!  The E.P.S. Ai uses is a closed cell with a 1 lb. per cubic foot density. The insulation is permanent, chemically and thermally stable; resistant to mildew; provides no nutritive value to animals, plants, microorganisms; non-irritating to skin.  The insulation will not rot, shrink, absorb moisture, compact, or deteriorate due to age or the weather. It also acts as a vapor barrier for your home, providing stable performance year after year. To learn more about E.P.S. as a Vapor Barrier click on Vapor Barrier.

ANALYSIS OF EXPANDED BEAD POLYSTYRENE

The Expanded Polystyrene (E.P.S.) Insulation that American Ingenuity utilizes is seven inches of sturdy, rigid R-28 modified E.P.S. insulation, which forms the core of each component panel. The E.P.S is one pound per cubic foot density (pcf).  EPS is NOT Styrofoam.

The E.P.S. insulation will not rot, shrink, absorb moisture, compact, or deteriorate due to age or weather. It also acts as a vapor barrier for your home, providing stable performance year after year.  The E.P.S. that American Ingenuity utilizes in its prefabricated panels:

  • is permanent
  • is chemically and thermally stable
  • is resistant to mildew
  • provides no nutritive value to animals, plants, microorganisms
  • is non-irritating to skin
  • contains NO Chlorofluorocarbon (CFCs) and is formaldehyde free
  •       Contains NO HBCD (hexabromocyclododecane) and NO TCPP (1-chloro-2-propyl) phosphate

What kind of vapor barrier will American Ingenuity dome have?  Approximately one quarter of the energy consumed by an air conditioner is used to extract water vapor from inside the house. Water vapor easily passes through most building materials and is readily swept into homes through joints, seams and through the attic. The E.P.S. insulation that Ai uses provides a good vapor barrier.   And the Ai building system provides for an air tight house.

During the US Dept of Energy Study on energy efficiency in  housing designs, the blower door test showed the American Ingenuity dome to be 56% tighter than the conventional test structure and 29% tighter than the Dow house.  To see if air was passing through walls of the dome, tests using infrared were performed. Thermal irregularities in the dome were shown to be insignificant.

Per the manufacturer of the E.P.S. which American Ingenuity uses, “the E.P.S. is closed cell and will not absorb more than 2.5% of water based on volume”.  E.P.S. is often used as flotation for docks because it will not absorb water. 

Per E.P.S. manufacturer’s data sheets the following description was given to explain how the E.P.S. is affected by Moisture:  “To retain their original insulation value, all insulation materials must remain dry.  Water is a good conductor of heat so a high moisture content in the insulation results in a significant loss of performance.  This is particularly so with fibrous materials which must be positively protected by an efficient vapor barrier.  Two ways in which moisture can affect insulation materials are; water absorption from contact with damp surfaces or rain penetration or from interstitial condensation of water vapor.  E.P.S. is a closed cell material and has minimal water absorption and low water vapor transmission.  Both of these properties are to a large extent, density related, but also to the degree of fusion of the material.  Tables 4 and 5 show typical performance figures for good quality E.P.S. boards manufactured to Arco Polymers recommendations.”

3.0                                                                                            0.5-0.7

The amount that a material will breathe is measured in perms or sometimes perm inches.

 “Note: FHA requirements for perimeter insulation are that the original K value of the material must not increase by more than 15% after repeated wetting and drying cycles.  Tests have been carried out on nominal 1.0 pcf density E.P.S. with an original K value (at 75 degrees F) of 0.26.  After submersion the K value was found to be 0.28–an increase of only 7.7%.”

 Climatic Changes:  E.P.S. board has been used as an insulation material in various types of building structures for over 35 years in climatic conditions ranging from Arctic cold to desert heat and has performed satisfactorily.  E.P.S. does not become brittle at sub-zero temperatures (in fact its K value improves) and suffers no loss of impact resistance at -100 degrees F compared with 73 degrees F.  The maximum recommended continuous operating temperature is 175 degrees F.  Roof surface temperatures in Southern States may reach this temperature for short periods, but with suitably designed roof systems E.P.S. can be used under these conditions.”

In Ai’s building system the water is stopped on the outside surface because the concrete is rich and dense enough to inhibit significant absorption and it is coated with a primer and two coats of good quality exterior concrete paint which further insures against leaks.  If a leak occurs the remedy is to check the area for hair line crack that gets repaired with elastomeric patching compound and another coat of paint.  If and when any water gets past the concrete very little will be absorbed by the E.P.S.

Now this brings up breathability of the E.P.S.  The amount that a material will breathe is measured in perms or sometimes perm inches.  E.P.S. will breathe enough to allow it to dry out inside our walls.  At the same time it is tight enough to also serve as a good vapor barrier. Ai’s insulating concrete panel (ICF) is made from expanded polystyrene (E.P.S.) molded into lightweight foam blocks. The foam itself provides excellent insulation with an R value of R-28. The R-value of E.P.S. remains constant. (R-values of traditional fiberglass insulation decreases when the material is wet or damaged.)  Ai chose to manufacture its dome component panels with Modified Expanded Polystyrene (E.P.S.) foam because of its fire performance, structural performance, and environmental advantages. Modified E.P.S. contains no formaldehydes, no CFCs, no HBCD, no TCPP or toxic chemicals, and uses fewer resources to manufacture than other insulation products.  E.P.S. provides you with superior thermal performance to better insulate your buildings, and no harmful CFC’s have ever been used to manufacture it.

You can now recycle your jobsite scrap through a network of manufacturers, re-processors, and retailers across the country. E.P.S. is a valuable resource than can be remanufactured into foam packaging or made into an amazing array of polystyrene products from office supplies to video cassette cartridges.  To locate your nearest E.P.S. collection site, call the RECYCLING HOTLINE at 1-800-944-8448.  Please recycle jobsite scrap.

Expanded Polystyrene (E.P.S.) Facts

The E.P.S. that American Ingenuity utilizes is manufactured from expandable polystyrene beads containing a hydrocarbon blowing agent and a flame-retardant additive that contains NO HBCD (hexabromocyclododecane) and NO TCPP (1-chloro-2-propyl) phosphate. Ai’s insulation is made from Nova Chemicals M-77 E.P.S. product.

The EPS Ai utilizes is a closed cell, lightweight, resilient, foamed plastic composed of hydrogen and carbon atoms. There are two common types of polystyrene foam, Extruded Polystyrene or X.E.P.S. (Popularly known by its Dow trademark, Styrofoam) and Expanded Polystyrene (E.P.S.). American Ingenuity utilizes only Expanded Bead Polystyrene that contains NO HBCD, NO TCPP, NO CFC’s and NO formaldehyde. Ai does not use Styrofoam.

During the processing of E.P.S., steam heat softens the beads and causes the blowing agent to expand to produce moisture-resistant multi-cellular particles, which increase in size up to 40 times their original volume.  Following a period of stabilization, during which time the beads lose their moisture, the blowing agent condenses out and air diffuses into their cellular structure, the pre-expanded beads are molded into blocks of insulation.

The benefits of E.P.S. thermal insulation products are its lightweight, has stable long-term thermal resistance, no R-value loss over time (Source: 1985 Study conducted by Structural Research, Inc. for NRCA, MRCA, and SPI), and cost effectiveness when compared to other rigid board insulations on the basis of R-value.

Is E.P.S. a water, vapor or air barrier?

E.P.S. is considered water resistant and vapor permeable and at the density and thickness that American Ingenuity utilizes, the material acts as both a vapor retarder and an air barrier. This characteristic essentially moves the dew point to the exterior side of the concrete wall, minimizing interior humidity in the summer, and at the same time eliminates air infiltration in all seasons which is recognized as a major cause of R-value loss in fiberglass insulation. Air exchangers or heat recovery ventilation systems are highly recommended!

Is E.P.S. foam toxic?

E.P.S. is an inert, non-biodegradable organic plastic foam which will not rot and is highly resistant to mildew. According to National Bureau of Standards Combustion Tests, data collected from seven labs concluded that under the worst case fire scenario, fumes from E.P.S. are no more toxic than those from wood (Douglas Fir).  

Is E.P.S. Flammable?

Due to the flame retardant added to the EPS during expansion, the EPS is not combustible but will melt and draw back from a heat source.  Tests have shown that the smoke and soot produced from the melting EPS is less than is produced by burning Douglas Fir wood.  Of course no one wants to breathe smoke or soot…that is why there are smoke detectors to alert occupants to fire.  The requirements of all the major code organizations for foam plastics is that they have a flame spread of not more than 75 and a smoke development rating of not more than 450. The foam used in Ai’s component panels has a flame spread rating of 15 and a smoke development rating of 125 based on ASTME84-87 tests, well below the code requirements.

If you are in an extremely cold climate (Vermont, South Dakota, Canada) you may want to purchase 9″ EPS R36 insulation.  Just remember if you purchase the thicker insulation, this will increase the size of the panels, which will cause a 45′ r 48′ kit to require two trucks for delivery.

1/2″ Georgia Pacific DensArmor Plus Gypsum Wall Board

Drywall/WallBoard: Consists of Georgia Pacific 1/2″ DensArmor Plus High Performance Gypsum Panels adhered to the E.P.S. insulation with a wallboard adhesive  with moisture treated core.  DensArmor Plus High-Performance Interior Panels are noncombustible (as defined and tested in accordance with ASTM E136 or CAN/ULC S114) interior panels that consist of a moisture-resistant gypsum core with coated fiberglass mats. The fiberglass mats provide superior protection from incidental moisture.  The treated core and the coated facings made with fiberglass offer greater moisture resistance and improved dimensional stability than regular gypsum board. The product resists warping, rippling and buckling.

The DensArmor has zero flame spread and zero smoke development and complies with the 15 minute thermal barrier test as described in 2010 Florida State IRC Section R316.4.

Georgia Pacific’s Dens-Deck roof board is a patented nonstructural glass mat-faced, noncombustible, water-resistant, gypsum core panel.  Georgia Pacific does not add any flame retardant to its gypsum products.  The DensArmor contains no HBCD and no TCPP.

Q: Does the interior shell wall board that American Ingenuity uses support the growth of mold?
A:
. DensArmor Plus Panels are highly resistant to the growth of mold, and have scored a 10, the highest level of performance for mold resistance under ASTM D3273 test method. DensArmor Plus Interior Panels are the first drywall panels to be GREENGUARD indoor Air Quality Certified and GREENGUARD Children & Schools Certified for low emissions of volatile organic compounds (VOCs) by a leading third-party organization, GREENGUARD Environmental Institute.  In addition, DensArmor Plus interior Panels are the first drywall panels listed as GREENGUARD microbial resistant.  This listing means Dens-Armor Plus Panels, which feature fiberglass mats instead of paper facings used on the surface of traditional gypsum board products, resist mold growth.  The microbial resistant test is based on ASTM D6329, a testing standard set by ASTM International, which develops testing guidelines and procedures for building materials, products, systems, and services.

Green, brown or black algae can appear on the wallboard. Algae just needs water and sunlight to grow.  Algae can be removed with a combination of chlorine and water or oxygenated bleach and water.

The wallboard is adhered to the EPS with a wallboard adhesive.  The glass mats embedded into the core on both faces, results in dimensional stability and prevents warping. The glass mat is encapsulated with a coating which reduces skin irritation from exposed glass fibers. Please use a mask when cutting the DensArmor.

How are the panels supported during assembly?  Ai recommends using the temporary “wooden rib system.” The rib system consists of your own 2×4’s (cut to length and holes drilled to our specs) and steel hubs on loan from American Ingenuity to erect a free standing geodesic framework. The 2×4’s can be purchased from Ai (precut, holes drilled with ends painted) and shipped on the truck with your kit. The deposit on the hubs is $1,600 for a 5 month rental time…$20 a month rental thereafter, with the client paying to ship the hubs back to Ai to receive their deposit back less any additional months rental and any cost for any missing or damaged hubs. The bolts/nuts/washers are purchased for $128 and are not returned to Ai.  An Expanded Assembly Manual is now available with each new dome order.

The “Rib System” dictates the exact panel placement. Once all the seams/options have been concreted and entryways/dormers framed in the “Rib System” is removed and recycled into the interior framing and the hubs returned to us.  Click on Rib to learn more.

How are the panels hoisted into place? And what equipment is attached to the panels to make lifting easier?

  • The typical method for lifting the panels is by man lift, crane or transverse fork lift.
  • Monthly rentals on transverse lifts also called Boom Lifts, Horizontal Boom Fork Lifts, Roofing Lifts, Shooters are available from National Rental Chains.
  • Four Panel Lifting Spikes are purchased from Ai for $120 and attached to your locally purchased chain and couplers.  To learn more about the spikes click on Lifting Spikes.  Please scroll down the page to find the spikes info.
