Broadwell strictly follows the international codes for air inflated structures set forth by the International Code Council (
Full code descriptions for air-inflated structures:


We use the highest quality, PVDF vinyl fabric in the industry. It is thick, has a high insulation value, and is the stronger than fabrics offered by most other dome companies. It has an anti-UV coating, is anti-fungal and anti-mildew, flame retardant, self-cleaning, and has a 25 year useful life. Fabric can be translucent or opaque, and there are a variety of colors available. Printed banners and advertisements can easily be affixed to the outside or inside of the dome.





Our patented cable harness system creates a true fortress of reinforcement around dome for maximum protection. This design has the ability to support over 50 lbs per square foot of snow load (8-10 feet of accumulated powdery snow), exceeding minimum building standards. The dome can also be engineered to withstand 150+ winds.

The quilted diamond cable pattern of the dome carries most of the dome’s structural load. Any snow or wind loads are evenly transferred by the cable system to the dome anchorage and foundation. This ensures that only a small portion of the dome’s structural load is carried by the dome fabric.




Our dome package includes a powerful air inflation or HVAC system that can continually keep your dome inflated. Designed in Italy, our air handling units are the product of continuous, exhaustive product research and development for nearly 50 years.

  • Highly Efficient, Low Operating Costs
  • Exclusive Design and Construction = Strength and Reliability
  • Noise Reducing Technology
  • Self-regulating: adjusts air temperature and pressure automatically
  • Can be monitored remotely from any computer or mobile device
  • Includes air conditioning and/or heating capabilities
  • Multiple air filtering options available including UV sterilizing light, ionizer, or photo catalytic oxidation  



In the event of a power failure, our dome packages also include anemergency backup air inflation system that will automatically engage in the event power is lost. It is run by a generator that can be fueled by gasoline, diesel, natural gas, etc. 



Our domes utilize state of the art, wide coverage LED lights to reduce energy costs. Our engineers will determine the optimal LED lighting set up for your dome, and include it in your dome package.




The dome will be anchored into a galvanized steel beam reinforced by concrete. When the dome is not installed, the anchoring system will be covered by field turf. The anchoring system will be installed by a local contractor, guided by engineering drawings from our engineers.




Your dome will include air lock doors, which maintain air pressure as people enter and exit the dome. Very large air lock doors—large enough for vehicles—are also available. We also include emergency exits on each wall of the dome in case of an emergency.
