Abstract
A composite board is disclosed comprising a core and at least one non-woven mat interfaced with the core, the non-woven mat comprising a plurality of glass fibers having a Young's modulus of greater than or equal to 85 GPa bound together by a binder. The composite board has an improvement in fastener pull-through strength, measured in accordance with ASTM D1761 of greater than or equal to 15%, as compared to an otherwise identical composite board including a non-woven mat comprising a plurality of glass fibers having a Young's modulus of less than 85 GPa.

A composite board comprising:
- a core;
- and
- at least one non-woven mat interfaced with the core, the non-woven mat comprising a plurality of glass fibers having a Young's modulus of greater than or equal to 85 GPa bound together by a binder;
- wherein the composite board has an improvement in fastener pull-through strength, measured in accordance with ASTM D1761 of greater than or equal to 15%, as compared to an otherwise identical composite board including a non-woven mat comprising a plurality of glass fibers having a Young's modulus of less than 85 GPa.
The use of a non-woven mat in a composite board, the non-woven mat comprising a plurality of glass fibers having a Young's modulus of greater than or equal to 85 GPa bound together by a binder, wherein the composite board has an improvement in fastener pull-through strength measured in accordance with ASTM D1761 of greater than or equal to 15% as compared to an otherwise identical composite board including a non-woven mat comprising a plurality of glass fibers having a Young's modulus of less than 85 GPa.
