An aliphatic polyurethane film is utilized as the primary glazing material for greenhouses and other heat-gain enclosures such as pool covers and sun rooms. The film is preferably a thermoplastic aliphatic polyurethane film having good abrasion resistance, low temperature flexibility, ultraviolet resistance, and strength characteristics. Lightweight portable greenhouses and modular high-performance greenhouses are made possible by the system.
