Abstract
A composite roof/roof deck assembly and method of installation wherein a roof covering of polymeric sheet material is adhered to an underlying mineral board roof substrate with a water based polymeric adhesive.
Claims19
A composite roof/roof deck assembly comprising a substantially rigid substrate layer;
- a substantially continuous polymeric sheet disposed over said substrate layer;
- and a water based, polymeric adhesive comprising:
- methanol, dionized water, acrylic acid polymer, sodium hydroxide, polyvinyl alcohol/vinyl acetate, polyisoprene latex, and aluminum silicate disposed between said substrate layer and said polymeric sheet to join said substrate layer to said sheet.
A composite roof/roof deck assembly comprising corrugated steel, mineral board overlying said corrugated steel and connected thereto by fasteners extending through said mineral board and said corrugated steel, water based polymeric adhesive overlying said mineral board, and a polymeric sheet overlying said water based polymeric adhesive.
A method for constructing a composite roof/roof deck assembly comprising the steps of installing a substantially rigid substrate layer comprising mineral board face with paper on at least its upward and downward facing major surfaces;
- distributing a substantially continuous coating of water based, polymeric adhesive comprising methanol, deionized water, acrylic acid polymer, sodium hydroxide, polyvinyl alcohol/vinyul acetate, polyisoprene latex, and aluminum silicate over the upward facing surface of said substrate layer;
- spreading a rubber sheet of ethylene propylene diene terpolymer over the water-based polymeric adhesive;
- applying downward pressure across the upward facing surface of the polymeric sheet to enhance contact between said upward facing surface of the substrate layer and the downward facing surface of the polymeric sheet with the water based, polymeric adhesive therebetween;
- and allowing the water based, polymeric adhesive to dry, thereby adhering the polymeric sheet to the upward facing surface of the underlying substrate layer.
