An inflatable dome, “bubble,” or air supported structure is a building formed from one or more layers of fabric. Air blowers continuously pump air into the structure, creating the necessary air pressure that allows the fabric envelope to stay inflated. Cooling or heating HVAC units can also be used to adjust air temperature.
The fabric envelope may be reinforced by Broadwell's patented steel cable harness system. The dome is anchored by a variety of anchoring options, including grade beam concrete footing, earth anchors, sand or water ballast, cement blocks, etc.
