Claims12
A glazing structure comprising one or more impact and fire resistant window layers comprising;
- A) a first glass or plastic layer;
- B) a fire resistant layer of a composition which essentially comprises about 10-40% by weight of tris (hydroxymethyl)aminoethane aminomethane, about 10 to 30% by weight of a member selected from the group consisting of ammonium phosphate, phosphoric acid, ammonium dibasic phosphate, ammonium dihydrogen phosphate, and triammonium phosphate;
- and about 35 to 65% by weight of a member selected from the group consisting of alkali metal borates, ammonium borate and its hydrate, sodium teraborate decahydrate, sodium borate, potassium borate, lithium borate, sodium meta borate tetrahydrate, boric acid, boric anhydride, boric oxides and ammonium borate, adjacent said first glass or plastic layer, and
- C) a second glass or plastic layer adjacent said fire resistant layer.
