- Lightweight —The 195 ft2 roll weighs only a fraction of what competitive materials weigh making transport and handling easier.
- Self sealing — The membrane meets key building code standards for nail sealability of self-adhered roofing underlayments.
- Easy to handle and apply — The membrane is easy to reposition, easy to install, bonds to the roof deck and forms high quality laps.
- Slip resistant surface — The slip resistant surface maximizes traction for safety without compromising the water integrity of the laps. The surface film is resistant to scuffing and tracking oil in hot weather.
- Reroofable — Unlike granular surfaced membranes, GRACE SELECT™ membrane will not adhere to the underside of the exposed roof covering making reroofing easier and less costly.
Description
GRACE SELECT™ roofing underlayment is 25 mils (0.64 mm) thick making it lightweight and easy to handle and apply. The unique, advanced rubberized asphalt formulation allows the membrane to meet industry standards for fastener sealability equivalent to products that are often significantly thicker and heavier.
The rubberized asphalt is backed by a paper release liner that protects its adhesive quality. The release liner is easily removed allowing the rubberized asphalt to be bonded to the roof deck.
The membrane comes in a 195 ft2 (18.1 m2) roll, and measures 36 in. (914 mm) wide. The RIPCORD® embedded in the adhesive provides the applicator a “split release on demand” feature, making it easier to apply in detail areas.
