Use of fibrous mat-faced gypsum board in exterior finishing systems for buildings
First Claim
1. An exterior insulation system for a building comprising a glass mat-faced gypsum support surface, insulating material having an inner surface and an outer surface, the inner surface of which is adhered to said support surface by an adhesive material, the insulating material being substantially free of channels penetrating therethrough and between said inner and outer surfaces, and an exterior finishing material overlying the outer surface of said insulating material.

Abstract
An exterior finishing system for a building, including particularly an exterior insulation system, which includes a fibrous mat-faced gypsum board, preferably a board in which the set gypsum core thereof is water resistant, and preferably one in which the set gypsum core is sandwiched between two sheets of porous glass mat, with the outer surface of at least one of said mats being substantially free of set gypsum, and means for preparing the board, including control of the viscosity of the aqueous gypsum slurry from which the set gypsum core of the board is formed. Also, the use of fibrous mat-faced gypsum board as the shaft liner panel in a shaft wall assembly.

- 11. An exterior finishing system for a building comprising an underlying structural support element which is covered with an overlying finishing material, said support element including gypsum board comprising a set gypsum core sandwiched between two sheets of porous glass fiber mat, the gypsum core including one or more additives which are effective in improving the water-resistant properties of the board in an amount at least sufficient to impart to the board improved water-resistant properties.
- 19. An exterior insulation system for a building having a support surface including gypsum board comprising a set gypsum core faced with a glass mat, the gypsum core including one or more additives which are effective in improving the water-resistant properties of the board in an amount at least sufficient to impart to the board improved water-resistant properties, insulating material having an inner surface and an outer surface, the inner surface of which is adhered to said glass mat by an adhesive material, the insulating material being substantially free of channels penetrating therethrough and between said inner and outer surfaces, and an exterior finishing material overlying the outer surface of said insulating material.
