Waterproofing and Thermal Insulation:
ROOF CARE provides spray applied polyurethane foam systems as seamless waterproofing and thermal insulation for such sheet roofs. To assure best bonding of the seamless system, the roof is to be properly cleaned by compressed prior to the application. Once the roof is clean of dust and any other substances which may cause separation, the ROOF CARE application team sprays POLYFOAM Polyurethane Foam (in compliance with ASTM C1029-09) directly on the GI sheets to assure seamless and fully bonded waterproofing and thermal insulation. With this spray technology all joints and bolt holes are sealed and covered. The thickness of the polyurethane foam can be adjusted to achieve certain Thermal Conductivity Values (U-Value).
To protect the seamless waterproofing and thermal insulation, the Polyurethane Foam has to be covered with an acrylic UV resistant coating. This coating is an additional waterproofing layer which protects and prolongs the life cycle of the foam. This system build up assures the long lasting and reliable waterproofing and thermal insulation of roofs with GI Sheet Roofing.
