High Performance Glass-Reinforced Felt

Coverage w/2" Lap: 400 sq.ft.
Roll Size: 3´ x 141.5´

Gorilla Guard™ high performance underlayment for steep slope roof applications. Made to order for the true professional. Contractors across the country told us what they wanted in a high quality underlayment. We utilized new technology to create an underlayment with high performance features that out-performs typical organic felt by adding glass fibers. You´ll save time – and labor costs – by using the right product the first time.

 RECOMMENDED USES

A specification grade felt used as a waterproof barrier between the roof deck and the shingles. Gorilla Guard is glass reinforced, providing superior stability over standard #15 or #30 organic felt.
