ABSTRACT:
A double wall fabric panel unit for use as a wall section in the construction of inflatable buildings comprising an elongated exterior fabric envelope panel having a plastic coating on each side, and an elongated thermal liner panel having side edge strips heat-sealed to the exterior panel. The thermal liner has a foil layer facing the exterior panel and a white plastic layer on the opposite side. The side edge strips are periodically interrupted to provide air passageways to vent air from between the panels when the unit is rolled.
