Why Choose A Dome Home?
1. Lower Construction Cost
The efficient construction method involves less labor. A six man crew can build a 3000 sq. ft. secure concrete shell (including foundation, roof and exterior walls), in three to four weeks (plus time for mobilization). More space can be enclosed in a dome shape with less surface area. More than twice as energy-efficient as most conventional buildings, the dome needs only a fraction as much in heating ventilation and air conditioning (HVAC) equipment.
2. Faster Construction
The domes are sprayed-in-place on site. An air form of single-ply roofing material pre-fabricated to the specifications of the building is attached to a ring foundation and is inflated. Urethane foam is sprayed on the interior surface. A grid work of steel rebar pre-engineered for the particular building is attached to the foam shell. High-density concrete is sprayed over the interior, embedding the steel in the concrete.
Almost all construction is done within the inflated air form, allowing construction to take place generally uninterrupted by weather conditions. Materials are readily available.
When building a concrete dome you think in centuries, not years with a life span rated in the hundreds of years.
4. Save 50-75% on heating and cooling costs
The externally insulated concrete creates a passive solar shell.
Overall temperature transfer R value approximates an effective R-70. (Fly wheel effect)
The monolithic dome is seamless and nearly airtight.
Five times more fuel efficient than conventional building, energy costs have been rising continuously.
5. Less Maintenance
No more — Ice Dams
No more — Leaking Roofs
No more — Worry of snow loads and shoveling steep roofs
Very little painting to be done on exterior.
6. Fire safe
As disaster resistant as rock
Will not burn down – Solid concrete exterior walls
Any damage easy to repair on exterior
No better way to protect your family and loved ones
Built like a tank or under a mountain
The monolithic dome has survived them all:
500 to 600 PSF compared to conventional 40 PSF
8. Lower Insurance Cost
Because less risk
9. Beauty of Environmental Shells
“Round” – The world’s most perfect shape
10. Free Span
Hundreds of feet with no interfering beams and support post. The possibilities are endless.
11. Five Star Rating
The monolithic dome will meet or exceed the qualifications for a five star rated home by the Alaska Craftsmen Home Program.
12. Marginal Soil Building
Have been built in 40 states and 10 foreign countries on marginal soils because the monolithic dome leaves such a light footprint compared to other structures.
