Abstract

Composite transparent thermoplastic material for making agricultural greenhouses comprises at least two superposed films, the bottom film being made of a thermoplastic material with great resistance to the aging caused by ultra-violet radiation and the other(s) being made of a thermoplastic material that is opaque to infra-red radiation with a wavelength of over 8 microns. The material has a useful life longer than that of single films of the same thickness and the reduction in light transmission with the passage of time, in so far as it is due to corrosion, may periodically be made good by replacing individual layers. A liquid such as glycerin may be included between the films. The layers may be of polyethylene, ethylene-vinyl acetate copolymer or plasticised pvc. [GB2014513A]
