Tremco SA Underlayment
Tremco SA Underlayment is a self-adhesive underlayment used as a secondary water barrier under metal & asphalt shingles. It consists of a highly versatile bitumen compound with enhanced adhesion which helps it to stick to most surfaces like plywood, OSB, concrete, wood particle and gypsum cover boards. It’s surfaced with a tough woven polymer laminate surface which gives it excellent walkability. The adhesive compound and the tough surface together acts to provide excellent high temperature resistance which enables long exposures to weathering.
