Sigma group is the worldwide leader in air supported structures, integrating design, development and manufacturing in-house. From sports and recreation to industrial and military applications, Sigmal designs domes specific to each client’s needs. Sigma domes are the highest quality, most efficient, and most cost-effective in the industry. There are over 180 Siama Air Domes built in Russia, Turkey, Mongolia, China and other countries.

Unique Patented Bias-Harness Cable Net System

Our patented bias-harness cable net system evenly distributes both internal uplift forces and external environmental forces. Without this cable net system, the dome body would bulge due to the weight of the dome itself and any accumulated snow on top. This would flatten the top of the dome, further increasing the area for snow to accumulate and requiring more pressure to inflate the dome, putting unneeded stress on the structure. However, testing shows that with our bias-harness cable net system, the dome shape remains unchanged even when the internal pressure is increased to 500 Pascals (2.01 inH20).

Energy saving technology

80% energy savings compared to a conventional steel structure. A triple layer design, including insulation helps maintain the desired temperature inside the air dome.

Advanced automation control system

Our remote control mobile app allows full automation of your air dome from any smart device. The app will automatically adjust temperature, humidity, air pressure, and air quality with changes in wind, temperature, and snow fall. You can also monitor and manually change these parameters remotely from any smart device.
