ABSTRACT:
A double-glazing assembly suitable for horticultural and agricultural growing houses comprises two flexible light-transmitting thermoplastics film, especially polyethylene terephthalate films, separated by a spacing framework. Means are provided to evacuate the enclosure between the sheets during the day-time thereby improving the light transmission of the assembly. The assembly is also preferably provided with means for inflation to optimise the conservation of thermal energy during the night-time.
