METHOD OF APPLYING A HEAT REFLECTIVE COATING TO A SUBSTRATE SHEET
The method of applying a heat reflective coating (28) to a substrate sheet of construction material is directed to the coating of insulation material, such as fiberglass batts (10), at the time of manufacture. However, it may be applied to virtually any flat, planar sheet of material to provide insulating qualities as well as structural value to the material. Economies of scale are achieved by coating the materials at the time of manufacture, or at least at some centralized location. By completely encapsulating fibrous insulation (12) with an impervious coating (28), the emission of irritant fiber particles from the insulation (12) and corresponding health hazards are eliminated. Also, the efficiency of the insulation (12) is improved by sealing out moisture when the insulation (12) is completely encapsulated by the coating (28).
