CertainTeed WinterGuard HT Waterproofing Underlayment

Description

The CertainTeed Winterguard HT Waterproofing Underlayment is an advanced, self-adhering, high tack, high-temperature membrane that is made to withstand high roof temperatures up to 250°F under the metal roofs. It is designed for application underneath low slope shingle, low slope tile, low slope metal, and low slope slate roofs and is composed of a sturdy support that is impregnated and coated with asphalt that is SBS-modified. Winterguard HT has a film on the top that is tear-resistant and will not scratch the metal roofing that it is placed under. The bottom surface of the Winterguard is adhesive and it is covered with a release film that is silicone-coated. This release film is also split down the center horizontally for easier application. Winterguard can not be left uncovered for more than 6 months.Please Note: WinterGuard is a vapor barrier. Therefore, if WinterGuard is applied over a majority of the roof deck, proper deck ventilation must be provided. If WinterGuard must contact sealants or cements, use solvent-based products sparingly, following manufacturer’s instructions carefully. Excessive use of solvent-based adhesives can damage WinterGuard’s polymer modified asphalt coating. Do not use silicone-based sealants, as they do not maintain adequate long-term adhesion to asphalt.
