Gorilla Guard® 30

Asphalt-Saturated Felt Underlayment

Gorilla Guard® 30 is designed to outperform traditional felt roof underlayment by combining specially developed additives with glass fibers. The superior quality, time and labor saved by using Atlas engineered underlayment encourages more contractors to offer it to customers as a standard product rather than as an upgrade to traditional felt.
