IKO PrevENt MP-HD-Cap Fully Adhered Cap Sheet is constructed using a tough composite reinforcement of non-woven polyester strengthened with a glass fiber scrim in both machine and cross directions, which is coated top and bottom with select SBS polymers and premium asphalt. During the manufacturing process, expandable graphite is added above the reinforcement to impart excellent exterior fire resistance properties. Specially formulated for excellent fire resistance, PrevENt MP-HD-Cap’s ceramic coated mineral granules are embedded in the surface of the product to provide protection against ultraviolet radiation. PrevENt MP-HD-Cap can be used as a protective cap for a conventional BUR system or as the top ply in a two-ply Modiflex system.
