Abstract
Disclosed is a fire resistant, flexible vapor barrier sheet comprising a laminate of a metallized substrate sheet and a radiation cured resin layer containing an inorganic pigment. The vapor barrier sheet can be laminated to one side of an insulation bat to provide an attractive, fire resistant insulation product for use in walls of metal buildings and the like.

A vapor barrier comprising a laminate of a metallized substrate sheet and a continuous layer of radiation cured resin having fire resistant characteristics.
A vapor barrier comprising a metallized polyester sheet having laminated on one side thereof, a continuous layer of radiation cured resin containing titanium dioxide in an amount sufficient to impart fire resistance thereto, and further having secured on the other side thereof an insulation material.
A vapor barrier comprising a substrate sheet having metallized layer on one side thereof and a radiation cured resin layer on one of said metallized layer or the other side of said substrate sheet, said radiation cured resin layer containing an inorganic pigment in an amount effective to inhibit flame propagation by said resin.
A vapor barrier comprising a laminate of a substrate sheet sandwiched between continuous layers of a radiation cured resin, one of said resin layers comprising an inorganic pigment in an amount effective to impart fire resistance thereto and one of said layers having a metal layer disposed thereon.
A vapor barrier comprising a laminate of a substrate sheet sandwiched between continuous metal layers each having a layer of a radiation cured resin thereon, each of said radiation cured resin layers comprising an inorganic pigment in an amount effective to impart fire resistance thereto.
The method of making a normally flammable vapor barrier sheet fire resistant, comprising the steps of:
- (A) metallizing a substrate sheet;
- (B) coating a thin continuous film of resin precursor on the product of step (A);
- and
- (C) radiation curing said resin precursor, said resin precursor comprising an inorganic pigment in an amount effective to impart fire resistance thereto.
