BUTYL MP
FT Butyl MP (Multi–Purpose) Waterproofing Membrane
Butyl MP is a high temperature self adhered waterproofing membrane made with an advanced butyl rubber adhesive formulation and designed for use in steep slope roofing applications. It offers premium protection from water infiltration from snow, ice dams, and wind driven rain. Its a multi- purpose underlayment that can be used under most primary roofing materials including residential or commercial metal, adhesive foam set or mechanically attached concrete or clay tiles, primed cedar shakes, and asphalt or composite shingles.
FT Butyl MP features Traction Grip an embossed walking surface that provides improved slip resistance in all weather conditions. Traction Grip is a polyester reinforced fabric that is engineered for extreme environment tear strength and designed for applications requiring heavy foot traffic and longer installation times like tile, slate, or metal roofing. It also accommodates for tile stacking on the rooftop for an extended period.
