SPECIFICATION METALLISED FABRIC A microporous metallised fabric suitable for use as a thermally-insulating material in a hostile environment comprises a microporous fabric substrate for example of a spun-bonded polyethylene having a layer of aluminum deposited thereon by a vacuum deposition technique. A thin layer - typically of 0.9 - 1.0 g/m2 of a polyamide-based ink is then printed on to the metallising, by way of a photogravure printing process, in such a way as not to affect the porous structure of the metallised fabric. The metallised fabric of this invention finds a particular application as screening for commercial glass-houses, to reduce the heat-losses therefrom. |
