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 due to the triangle panel shape being the strongest shape among all shapes and because the steel mesh from panel to panel is overlapped, locked & covered with fiber concrete. As a result the continuous panel 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.

Hurricane Irma winds caused tree to uproot and fall on Aidome

The following two photos are of 40′ Aidome – dome had no damage just dent in a dormer 

Ai has heard from one of its dome owners whose steel reinforced concrete dome went through a tree impact caused by Hurricane Irma. The dome suffered no damage  – only a minor dent to a dormer.  This dome home was built in 2000 and is a 40’ dome linked to a 27’ garage dome located in Seminole County – central Florida.  Per the Orlando Sentinel  that area had 74 mph wind gusts with 50 mph sustained winds from Irma.  The following quote was emailed to Ai:  “I thought I’d send you this shot of a tree that landed on the dome during hurricane Irma.  My girlfriend was actually standing inside the doorway (inside the dome) when the tree hit and we both heard and felt the thud.  The tree is a Red Maple about 50’ tall. It uprooted from the ground and came to rest as you see in the photo.  It has a split trunk with a base dimension of 30” x 26”.  The two main trunks beyond the split are about 13” and  15” in diameter.  Once all of the smaller tree limbs were removed it was clear that the dome shell suffered no damage other than cosmetic paint scuffing and a minor dent in the edge of the dormer rim.  (fixable with Bondo or patching cement).  No cracks or other damage have been observed inside or out from the tree impact.  This is a testament to the strength of the dome!  I’ve also attached a shot of the tree with it’s branches removed so you get a clearer view of the tree itself without all the leaves and vines.  I’m still enjoying the dome living life after 17 years here now.”


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 50 lbs. to 90 lbs. per sq.ft.  Engineers have assisted Ai’s design team to design the dome to withstand 90 lbs per sq.ft. snow load.  Recently dome building plans were designed for Colorado at 90 lb snow load and 110 mph wind speed  which were engineer sealed for Colorado.

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.

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 R28 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 10″ of fiber glass batting.  If desired the Aidome insulation can be upgraded to 9″ thick expanded polystyrene (EPS) resulting in R36. In conventional houses the vertical walls have one R value and the roof has another R value requirement.  In the Aidome because all the panels which make up the walls and roof have the same R value, this means the Aidome will pass an Energy Report.  If your floor plan has four or five entryways with the glass maxed out, to pass an Energy Report the glass may need to be triple panned instead of the typical double pane glass.

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.



General FAQ on American Ingenuity’s Prefab Home Dome Kit.

Exterior Office lots of green

 45′ linked to 34′ – 3,700 sq.ft.  Domes were built in 1993

Q: How long has American Ingenuity been designing and manufacturing domes?

A: Established in 1976, Ai has continually been under the same ownership. Ai has sold domes into 47 states and 14 foreign countries.  The only states that Ai currently has no domes in are: Rhode Island, New Hampshire and North Dakota.

Ai domes have been exported outside the continental USA to: Hawaii, Puerto Rico, Trinidad, the Virgin Islands-St. Kitts and St. Croix, the British Virgin Islands-Tortola, West Indies-Nieves, Canada, Israel, Jamaica, Bahrain and the Faroe Islands (between Iceland/Scotland/Norway).

The first American Ingenuity dome was built in 1976 after two years of design research. Founder Mr. Busick employed the talents of the Director of the Florida Solar Energy Center, University engineering students and an architectural professor to design the very first Expanded Polystyrene (E.P.S.), concrete and steel geodesic dome.

Normally American Ingenuity does not assemble the dome kits but because this was our prototype, the dome was built by propping up the precut E.P.S. insulation panels, hand tying steel mesh to the exterior of the insulation and spraying concrete over the entire dome exterior. This first dome became the office and model of American Ingenuity and by our standards was a primitive design. There were no riser walls or performed entryways or dormers at that time.

Countless designs and construction techniques were analyzed in the early years as we developed a new generation in housing and designed our special component panel. American Ingenuity received a patent on its panel in the early 80’s. These pre-concreted panels produce a better quality home and eliminate the need for costly concrete pumping equipment.

Ai has progressed from a prototype structure to a home that has received a design competition award and three energy awards along with exposure through numerous articles in national magazines, on Inside Edition, on Film and Garden, front cover of Popular Science and other media. Ai outgrew two previous locations as we progressed to our current five-dome complex. Ai’s Building Plans have progressed from simple hand drawings to a detailed computer designed set of blueprints.  American Ingenuity’s Building Plans are new and improved. An Expanded Assembly Manual is now available with each new dome order.  Ai was the first to offer second floor door dormers/balconies on a dome.

Q: Can I view an American Ingenuity dome?

A: The dome kits American Ingenuity sell become private homes. Ai would like to have model homes throughout the country but it is not economically possible. If Ai did have models, we would need to double the price of the building kit to pay for the model construction, the staff to man them and the annual costs to run, pay property taxes, etc. There are over 800 American Ingenuity domes throughout the country but they don’t belong to us and we can’t extend invitations to see them. However we are very happy that a few dome owners allow us to give out their name and number. So a referral could be a few states away from you.

Our referrals love their domes and are very happy to speak with potential owners. However, since they are not dome sales associates, we promise them that we will speak with each perspective buyer to answer their basic questions and walk them through significant pages on our web site. Ai tries to answer the multitude of potential buyer questions so as to not take up hours of the referral’s time with basic and in depth questions. As a result, please call our office and our friendly staff will be happy to talk with you and later provide a referral.To view free info, click on Info.  To view pictures of different America Ingenuity dome homes, click on Photo Galleries to view photos of finished domes and domes under construction.

Q: Does your customer service staff work on commission?
No. What we have found best is to offer good customer service and not twisting anyone’s arm to purchase a dome. Just call or email your questions. We stay in contact with our clients with a newsletter. If you would like to receive the newsletter go to our web site’s home page and enter your name and email address under Newsletter.

Q:  I hear that American Ingenuity recommends solar tubes instead of skylights  – please explain why?

A:  Ai no longer manufacturers skylight panels. For additional light max out the number of second floor window dormers and door dormers. In the door dormer install a tall window instead of a door. Or on site install Solar tube in the panel NOT skylight. Skylights allow too much hot or cold air into the dome. Solar tubes unlike traditional skylights, are designed to control the problematic aspects of sunlight. They reduce glare and inconsistent light patterns. They also screen infrared rays that can overheat interiors as well as ultraviolet rays that can fade furniture and fabrics.  Solar tubes have the following names:  tubular day lighting devices, or TDDs for short are also called “tubular skylights,” “light tubes,” “sun pipes,” and even “light tunnels.”

Q: What does frequency mean in relation to domes?
Frequency is simply the number of segments between the centers of pentagons in a geodesic dome. To best visualize this, first note the five panels that make a pentagon at the top of the dome. Follow any of the seams that radiate from this pentagon center to the center of another pentagon. There will be three segments in a three frequency dome; in a four frequency it will be four; in a two frequency, two. A soccer ball exemplifies a three-frequency icosahedron. A typical golf ball utilizes dimples in a six-frequency design. If you are a contestant on a quiz show, or become a proud dome owner, this bit of trivia may be of help to you.

Ai’s 15′ & 18′ domes are two frequency, 1/2 spheres on a 4′ vertical riser wall with an additional 2′ riser.

Ai’s 22′ and 27′ domes are two frequency, 1/2 sphere on a 4′ vertical riser wall.  Or the 22′ kit can have a custom 5′ riser instead of the 4′ riser.  An additional 2′ riser can be ordered for the 27′ dome. 

The 30′, 34′, 40′, 45′ and 48′ domes are three frequency, 3/8 spheres on a 4′ vertical riser wall. An additional 2′ riser can be ordered.

American Ingenuity has developed a dome that is approximately a one-half sphere with a four foot tall riser wall. All of Ai’s building plans and manufacturing specifications are for 3/8 domes on a four foot riser.

5/8 Domes:

  • Ai finds it more practical to use a vertical 4′ riser wall on all of its domes instead of designing its domes with the 5/8 geometry.
  • Ai’s 30′ dome turns out to be almost the same height as a 5/8 dome.
  • Also the 4′ riser wall makes for a better shaped entryway and allows the dome to link with all of our other size domes.
  • Ai can manufacture a 5/8 dome but none of our predesigned entryways will fit. And the location of the second floor will be different and difficult for us to design because our predetermined supports will no longer work. As a result the framing design will cost more than we normally charge. Call our office for more information.

Q: What is the largest American Ingenuity dome available?
Prompted by requests for a large, single dome for commercial uses, we developed a 60′ dome in 1988. It can be built for a warehouse or storage building  All the 60′ building plans are custom plans. The 60′ dome will cost more per square foot to assemble than the smaller domes because of the greater number of panels and the height of the dome. The 60′ dome requires two trucks for delivery.
If you need a larger dome than this, contact Monolithic Dome in Italy Texas. 

Q: What is the shipping cost?
Because Ai’s Building Kits are reasonably priced, even with the addition of the shipping cost, your dome home kit will be more affordable than you think. Having our manufacturing plant located in Florida is advantageous for shipping since more is shipped into than out of the state, leaving many trucks headed out empty.

Using an independent trucking agency, Ai contracts to have these trucks carry the building kits for a low cost of approximately $2.70 to $2.90 per mile or a minimum of $800 for Florida sites north of our factory.  Call for shipping costs to Florida sites south of Ai’s factory.  This is less than we could do with our own trucks. Most of the time each flatbed truck can carry one large building kit or two 22’s.  Per mile shipping costs can vary at any time due to fuel costs, fuel surcharges and travel distances.The small 15′ and 18′ dome kits can be picked up with a trailer and 3/4 ton pick up truck. Call us for details. 321-639-8777.

The number of multiple kits that one truck can carry varies depending upon the number of entryways, dormers, size of insulation, etc. with each kit. The entryways and dormers take up more room than triangles or riser panels. Once your floor plan has been finalized, Ai can determine the number of trucks that will be needed for your shipment.

Florida sales tax and surtax are not paid on building kits shipped out of the state of Florida.

Each trucking company has cargo insurance. Ai communicates with you and gives you the name/cell number of the truck driver so you can also communicate with him. Shipping is paid with the kit balance two weeks prior to the kit shipment date in the form of a bank check.  The truck is unloaded an all-terrain forklift (2,000 to 3,000 pound lift capacity) that you rent locally. Please have an experienced forklift driver and at least two to three people to assist the fork lift driver. Click on Shipping to learn detailed information on the unloading of the semi-truck.  Ai emails the Truck Unloading document which contains precise details for kit unloading.

Two of the main reasons Ai’s Dome Building Kits are reasonable in price are first: labor costs are less in Florida than out west or up north where most housing kits are manufactured. Second: because of Ai’s component panel design, your building kit contains all the R-28 insulation & 1/2″ DensArmor and 80% of the finished concrete exterior already installed.

In comparison with other building kits besides purchasing the building kit

  1.  the insulation is usually purchased separately and installed separately
  2.  roofing is usually purchased separately and installed separately
  3. the drywall is usually purchased separately and installed separately  

Please click on Panel Composition to learn about Ai’s panel.  As a result of Ai’s prefabricated panel’s contents, normally Ai’s Building Kit is about one third to one half the cost of other housing kits. So even, when you add the shipping cost to the American Ingenuity Kit pricing, the total is still less than other housing kit’s pricing.

Q: How does the weight of these domes compare to other houses?
Because of the reduced surface area of a dome and its thin shell construction, American Ingenuity domes weigh less than the average house, but are remarkably stronger than other types of structures. Domes are considerably lighter than a concrete block house.

The Ai dome foundation does not require anything more than 2000 lbs. per sq.ft. soil bearing capacity.  If there is any doubt about your soil, please hire a soil report. To complete this report, the company will bore test holes in your soil and evaluate your soil. A soil engineer with the company will review the data and make a recommendation of what type foundation your new home should be built on. Because you are building a super-strong American Ingenuity dome you want to assure your foundation is built on correct foundation.

Q: Are American Ingenuity concrete domes manufactured in any other location?
No. Our manufacturing costs here in Florida are well below the national average, which offsets any long distance shipping expense. We can actually manufacture a kit here in Florida and ship it cheaper than we could manufacture it elsewhere.

Q: What are the advantages of the dome shape?
The dome, or partial sphere, is a geometric form that encloses the greatest amount of volume with the least amount of surface area. Historically, massive domes constructed of stones, brick or concrete were common in ancient Greece and Rome. In modern times, Buckminster Fuller was the first to formulate geodesic principles for constructing a spherical surface by triangular subdivision.

During the past decade the home buying public has experienced a substantial increase in the cost of construction, the cost of energy and the cost of borrowing. As a result, there has been increased interest in the use of technology to help address these concerns. In the last decade, many people have discovered that the dome home design offers a viable solution.

As a residential building concept, geodesic dome home construction translates into a highly comfortable and livable home that has a maximum of floor area enclosed by a minimum of materials. These features combine superior strength and cost-effectiveness in a single structure. In short, the building concept of a dome home expands the range of simple and economic housing options.

Manufactured dome homes are constructed using a triangular network to form a spherical shape. This method provides for a free span, self-supporting structure requiring no internal supports such as roof load bearing partition walls. This allows for maximum flexibility of floor plan design and utilization of interior space.

As an architectural form, the dome is one of the strongest structural forms devised and built by man. Domes that were built centuries ago enclose many of the great cathedrals of Europe. Domes are structurally superior to rectilinear enclosures. The partial sphere is an aerodynamic shape that is very stable in high winds and can withstand heavy snow loads. For these reasons, residential domes greatly exceed the structural requirements of the major building codes in the United States.

One of the most exciting architectural environments ever designed, a dome brings its best attributes to your home. It delivers a rewarding living experience filled with warmth, light and open space to those who accept the challenge to build and live in their own dome. To learn more:

Q: Do you have any pricing comparisons?
A:   We have a few.  Please call and Ai will email those comparisons. 
 At least once a month perspective clients visit our office domes and inform us that our kit is at least one third to one half-less in cost than the shell materials for a conventional house or wooden dome or gunited concrete dome.  We believe when you do your own research that you will agree with our visitor’s conclusion.

The reasons why our kits have a better price is not magic.

  • The primary reason is the design concept. It is far more practical to build a dome with concrete than wood. Applying the concrete to rigid foam insulation produces a component panel that provides structure, exterior finish and the insulation.
  • Our philosophy of each person paying for only what they need results in a lower kit price as we do not have an 800 number, our literature prices are based on their printing costs, only our clients who need an engineering seal pay for one, etc.
  • Also we maintain a lower advertising cost; by marketing our dome on line.
  • None of our staff is on commission.
  • Due to lower labor costs in Florida, we can manufacture in Florida and ship to other locations cheaper than it would cost to manufacture there.

Remember to compare apples to apples when pricing each company’s kit. Ai’s component panel includes 80% of the steel reinforced concrete exterior, all the shell’s seven-inch thick R-28 insulation and all of the interior shell’s wall board. In wooden domes you will likely have to purchase the insulation, wall board, exterior finish and roofing at extra costs. Click on Stick Built to read more.

Q: What do the panels weight?
On the left side of our Home Page click on Dome Kit Sizes and Prices, then click on Specifications. Scroll down the page and you will find a category, Panel Weights. Depending upon the size dome, the panel’s weight from 155 to 400 lbs.

Q: What size land do I need?
The size property you would need for a dome depends upon the following items:

  1. What are the front, back and side setbacks for your property. Meaning how many feet does your building department require you to leave vacant along the front, back and sides of your property lines, well, septic tank and drain field?
  2. Do you want to drive a vehicle around each side of your house? When you know these answers you can add the distances up to determine the minimum width (dome diameter plus side set backs and any other space needed to drive a vehicle around the sides of your dome). The minimum length of land needed would equal front and back setbacks, lawn plus diameter of dome(s).
  3. To learn more click on Planning Process.

Q: What should I consider before purchasing land?
Call or email us, and request our latest buying land document that lists items to obtain answers before purchasing property.  Some of the biggest concerns are:

  • Does muck have to be removed and truck loads of fill brought in?
  • Are there any minimum house square footage requirements or garage requirements?
  • Are there any impact fees in order to build?
  • Are there any height restrictions?
  • Is there wetlands, or running water on the site causing environmental concerns?
  •  Are there any endangered plants or animals on your property?
  • Would you have to build your house on concrete pilings?
  • Are there any deed restrictions or homeowner associations governing what can be built on the land?
  • If you use a septic tank, will the soil perk?  Did your neighbors install a septic tank near your property line which will limit where you can install your septic tank?
  • If you do not have access to city water, what is the average number of feet your neighbors had to drill down to find water? What is the cost per foot to drill a well?
  • If there is no electricity to the site, will your neighbors sign easements so you can get electric lines to your site?
  • Do you have egress to the property via a road that is county or state maintained?
  • Are there front, back and side set back requirements which limit your building area, etc.?
  • Is there a county maintained road to give access to the property for emergency vehicles?

Q: Explain about painting the American Ingenuity Dome
The component panels do not come with any paint on them. Ai does not add any color to the concrete. On site, the seams are concreted if Ai painted the panels or added color to the concrete it would not match your painted seam concrete. The concrete shell is primed and painted after the entire kit is assembled.

  • In the Assembly Manual is a section on waterproofing that gives the latest info on primer and paint.
  • Stain is not used because stain will not seal the concrete.
  • The painting of the dome includes a concrete primer and two coats of good quality exterior concrete paint.
  • The dome can be painted any color, tan, green, blue, etc. preferably a light to medium color to reflect the sunlight.

It is not difficult to paint the dome….there are no soffits or gutters to have to deal with. Repaint the dome when you rub your hand on the paint and it chalks. Prior to painting, remove any algae with combination of chlorine/water or oxygen bleach and water and pressure wash.  Best to roll the paint on so there is a good mill thickness per the painting guidelines.

Typically, the American Ingenuity dome is repainted every 4-5-6 years, it depends on your personal preference.

  • During construction, install five stainless steel eye bolts in the top of the dome around the exhaust pipe. One in each of the five top seams  A rope is tied thru one eye bolt and fastened to the worker’s harness.  Each eye bolt is installed 6″ from a top center pipe with vent cap. The pipe is installed during construction to later install exhaust fan which will remove water vapor out of top of dome.  The eye bolts keep the rope away from the pipe with vent cap…so no rubbing on pipe to harm it.  There is a document in the Assembly Manual that describes this pipe and eye bolt installation.  The vent pipe, vent cap, exhaust fan and eye bolts are purchased locally.
  • The sides of the dome can be painted using a cherry picker or an extension ladder and paint roller on a pole. To paint the top of the dome stand on the dome with the rope tied to harness or stand in a cherry picker.
  • Yes you can walk on top of the domes.
  • To access the top of the dome put an extension ladder to a second floor dormer and then walk onto the top of the dome from top of dormer. Tie rope thru eye bolt and attach rope to harness. A person can sit in the harness and use pole with roller to apply paint or stand in a cherry picker. Current technology allows for a plastic tube connecting paint in bucket on the ground to painting pole. 
  • Do not use a sprayer to paint the dome as the spray is too thin a layer. The paint should be applied to the mil thickness noted on the paint can. Ai has found it is more efficient and quicker to paint the dome using a power roller attached to a paint sprayer to get this correct thickness. If the paint is applied in too thin a layer then UV light deteriorates it sooner thus causing the need to paint sooner.
  • Prior to priming and painting the newly concreted dome allow the concrete to be rained on for three weeks to one month to remove efflorescence. If not raining, then water down the concrete weekly with garden hose.

Paints and Primers

American Ingenuity is continually reviewing primer, sealant and paint info from the market place and from our dome owners. Paints recommended by dome owners:

  1. Ames Research Labs Maximum Stretch: At participating Ace & True Value Stores. If using Ames there are specific sealants and primer to be used.
  2. Sherwin Williams: Loxon XP Paint, Loxon Primer and Conditioner
  3. Richards Paint: Rich Flex 245 and  Rich Flex Alkali Resistant 100% Acrylic Masonry Primer
  4. Behr’s Premium Elastomeric Masonry, Stucco & Brick Paint –Home Depot
  5. Seal Krete Paint (pigmented) –Home Depot

Ames products are available at comparable or less costs than paint from Lowes or Sherman Williams or Home Depot and can be purchased at participating ACE and True Value Hardware Stores (does not have to be purchased out of Oregon).  Only negative is the paint coverage of Ames is less than the other paints described above.

To speak with Ames representative call 888-345-0809 and ask for Gene (direct line in Oregon).  To test the product purchase pints or single gallons from Gene and then purchase your 20 – 50 gallons in 5 gallon buckets from local ACE or True Value Hardware Stores.  Ames Products can be researched and videos viewed at when on their web site click on Products to view info about their Super-Primer, Peel & Stick Contouring Tape and Maximum Stretch Paint.

The main reasons American Ingenuity selected exterior concrete paint is because it is readily available, economical and easy for the beginner. Specialty paints like epoxy are unable to stretch and the epoxy paint can “in some areas” crack and allow water to pass through. In addition, any paint that would have a high gloss would highlight flaws in the seam finish. A paint that would withstand UV light or last longer would be advantageous but keep in mind that it is much easier to paint a dome than a conventional house.

Does the dome’s steel mesh ground out electrical line waves?
Yes. The entire dome except for the widows and nonmetallic doors is completely wrapped with steel. The steel mesh would block or ground electromagnetic radiation with the exception of high frequency in the order of what cell phones use. Radio and TV will possibly be blocked and the 60 cycle of power lines being very low frequency would definitely be grounded.

How resistant is Ai’s dome shell to termites? Based upon a FHA test, E.P.S. will not support bacterial growth or fungus growth. It also contains no food value to any living organism. Its lack of food value means that although termites, ants and rodents can tunnel through it, there is no other attraction.

Prior to when the slab is poured, the foundation area is treated for termites. After the dome is assembled, treat an area around the slab to stop the termites. In the USA, use termite stacks, etc. In addition, Ai has learned to keep mulch away from the sides of the foundation as mulch holds moisture for the termites.

There are no openings or cracks in the dome shell that would provide a path for insects. The windows, doors etc. could provide a path. Ask the window and door supplier how to seal them from bugs and termites. Concrete that is applied in the bottom riser wall seam overlaps the foundation concrete and is primed and painted.
