Abstract
A single wall airbeam constructed of a single layer material including a core of polyester fabric having a coating of adhesive on each surface of the polyester layer. A thin polyester film is applied to one of the adhesive layers. First and second polyurethane layers are applied to the other adhesive layer. The first polyurethane layer is a thicker, higher melt point polyurethane layer that may or may not be coated in a fire retardant material. The second polyurethane layer is a thinner, polyurethane layer having a lower melting point. An airbeam is constructed using one or more pieces of the fabric and heat sealing or welding the one or more polyurethane layers of fabric at seams, when the one or more layers are placed in a confronting position.
