Such structures vary in size, span, supporting systems and insulation demands. They could be built in various areas according to different construction codes concerning wind pressure, snow loads etc.
The present market offers a variety of fabrics' products. One may find fabrics which vary in size, weight, breaking strength, resistance to flex cracking, flame and tear propagation, as well as durability and guarantee given by the manufacturer.
