ToughSkin HT

ToughSkin HT Ice & Water Guard is a self-adhered underlayment that consists of our ToughSkin Slipsafe Technology coated with a rubberized asphalt adhesive. This technology allows for a superior adhesion over a large range of temperatures, including high temperature applications such as metal roof systems. Our skid-resistant surface includes our high tensile strength ToughSkin design while staying lighter for easier handling.



• Usage-for use as an underlayment on all sloped roof coverings including slate, tile, cedar shakes, metal, and traditional asphalt shingles • Seals around fasteners-the rubberized asphalt adhesive in the membrane seals around fasteners, resisting leakage caused by water back-up behind the ice dams or from wind driven rain • Deck Adhesion-the self-adhesive membrane bonds firmly to the roof deck without the need for mechanical fasteners • Watertight Laps- the membrane forms a watertight overlap due to the top coat adhesion strip • SlipSafe® Technology provides the ultimate in traction making the work surface safer during installation • Membrane will not crack, dry out or rot • Enhanced UV-180 days exposure • Class A Fire Rated ASTM E 108 (as part of system) • Siliconized release liner is easy to remove


Standard roll size is 36” wide x 67’ long, or 200 sq
