The present disclosure is directed to a composite useful as a building constructionmaterial, in which one or more textile scrims are attached to a nonwoven mat. Inone embodiment, a high elongation scrim layer and a low elongation scrim layerare attached to a nonwoven mat to provide high impact resistance and enhancedstructural support. In a second embodiment, a nonwoven mat is reinforced witha single scrim layer having both high elongation and low elongation yarns to forma composite. The scrim layers are preferably adhesively bonded laid scrims,although other scrim types or combinations thereof may also be used. Preferably,the high elongation material is made of polyester, the low elongation materialis made of glass, and the nonwoven mat is made of polypropylene. The resultingfunctional composite may be used as a housewrap or roofing reinforcement on vertical,horizontal, or angular exterior surfaces. |
