Abstract
Some embodiments of the present disclosure relate to an article comprising a reinforced glass mat. In some embodiments, the reinforced glass mat includes a glass mat and a reinforcement material. In some embodiments, the glass mat includes a web of glass fibers. In some embodiments, the reinforcement material is embedded into the web of glass fibers of the glass mat. In some embodiments, the reinforced glass mat includes a sufficient amount of the reinforcement material, so as to result in a nail shank shear resistance of 13 lbs to 17 lbs, when the article is tested according to ASTM 1761 at 140° F. Methods of making the article, specific embodiments of the reinforcement material in the form of a polymeric binder, and methods of forming a roofing shingle from the article are also disclosed.
