<p>PCT No. PCT/DE85/00087 Sec. 371 Date Nov. 4, 1985 Sec. 102(e) Date Nov. 4, 1985 PCT Filed Mar. 15, 1985 PCT Pub. No. WO85/04209 PCT Pub. Date Sep. 26, 1985.The fire proofing web is laid on a roof surface, in addition to the usual roof and insulating webs. It is intended to suppress or at least delay the occurrance of surface fires covering an area. At the same time, it is intended to form a vapor barrier. For that purpose, it includes, as the carrier web, an aluminium foil between two plastic foils. A glass fiber fleece with a content of crystalline-bound water is applied to a plastic foil as a lining thereon. In the event of a fire, the water evaporates and the resulting water vapor prevents or delays a surface fire or fire penetration.</p> |
