ArmourCool HD Cap is reinforced with a composite mat that is saturated and coated with SBS modified bitumen to a thickness of 4.0 mm (158 mils) (one roll is 1m x 8m, 8m area). This composite mat has an added fiberglass grid in the polyester mat, making it especially strong and dimensionally stable (better lay straight tendencies). Highly reflective mineral granules are embedded in the surface to provide protection against UV radiation, and a light poly-film is bonded to the underside (which disappears upon heat-welding).
