Abstract:
An impact resistant membrane and methods of preparing and utilizing the membrane are disclosed. The membrane comprises a loft layer, a first polymeric layer bonded to a first surface of the loft layer, and a second polymeric layer bonded to a second surface of the loft layer. The membrane can be fabricated by providing a loft layer and applying a polymeric layer on a first surface and on a second surface of the loft layer. The membrane has a higher resistance to failure due to impact and thus protects the underlying structure membrane for a longer time. A method of facilitating protecting a structure comprises providing a single ply membrane having a loft layer and a polymeric layer disposed on at least two surfaces of the loft layer.
