GAF has announced the industry's thickest triple-layer asphalt shingle. The company’s new Glenwood Shingles offer all the natural beauty and dimensional look of real wood shakes, blending luxury and style with ultimate performance. With ultra thickness and staggered exposure, the triple-layer construction provides maximum dimensionality, resulting in a truly authentic wood-shake look at a fraction of the cost. The shingles carry a Class A from Underwriters Laboratories. They also offer StainGuard® to help protect against blue-green algae, as well as Dura GripAdhesive to seal each shingle tightly and reduce the risk of shingle blow-off. Contractors who install Glenwood Shingles can give homeowners a Lifetime Limited transferable warranty with Smart Choice® Protection (non-prorated material and installation labor coverage) for the first 10 years.
