Patent ID: 7368150

Claim:
A method of improving the insulating efficiency, flame resistance, sound dampening, and mold and mildew resistance of building construction sheet materials, comprising the steps of: (a) providing at least one panel of building construction material at a manufacturing site therefor; (b) further providing a heat reflective, sound dampening, mold and mildew resistant coating material in a liquid state; (c) applying the heat reflective coating to the panel of building construction material at the manufacturing site of the panel of building construction material, to at least one side thereof; (d) air drying the heat reflective coating on the panel of building construction material; (e) providing at least one loose fiber insulation batt as the panel of building construction material; (f) bonding a backing sheet to one side of the loose fiber insulation batt; (g) coating the backing sheet with the heat reflective coating; and (h) coating the loose fiber insulation ban on both sides and all edges and ends thereof, completely encapsulating the insulation batt and imperviously sealing the insulation batt against moisture penetration.
