Air Structure Technology (In Brief)

Air-supported structures are a truly unique building system. They are supported solely by a slight change in air pressure within the fabric membrane using inflation fans. To compare the amount of pressure change required, a car’s tire generally
maintains an air pressure of about 35psi – an air-structure’s pressure is equivalent to about 0.35psi.

The membrane is manufactured from either 28oz or 32oz vinyl coated polyester fabric. A 15oz liner fabric is added to improve thermal and acoustic qualities.

In order to maintain the internal air pressure, specially designed revolving doors, pedestrian and vehicle air-locks are installed to allow easy access to the dome.

In addition to the primary heat and inflation unit, a standby mechanical unit powered by a generator is installed to protect the dome in the event of a power failure.

The fabric is anchored to a concrete grade beam which acts as ballast to hold the structure in place.
