The projection frame is made from PVC-coated fabric layers joined by high-frequency welding or mechanical sewing.
Screens can be held upright with help of a supporting structure (A-frame or inflatable legs) or with the system of straps and counterweights.
Even a small wind can make these fly like a kite without proper anchoring.
Inflatable screens reach sizes up to 560 square metres (6,000 sq ft).
Another big disadvantage of inflatable screens is the noise created by the continuous blowers.
