COMBINED APPLICATION PROCESS OF THERMAL INSULATION AND BUILT-UP ROOFING OR WATERPROOFING

摘要

This invention provides a combined application process for manufacturing a built-up bituminous roofing or waterproofing and thermal insulation assembly. The steps involved include placing a base sheet having on one surface thereof a compound layer on a foamed thermoplastic resin board so that the compound layer is in close contact with the foamed thermoplastic resin board, with the compound layer consisting essentially of a substantially pressure-sensitive self-adhesive composite material composed of at least two components selected from the group consisting of mineral oil, rubber, resin and animal or vegetable oil, and then coating the other surface of the base sheet with hot molten bitumen.
