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.
