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 Grip™ Adhesive 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.
