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.
Claims9
A single ply membrane comprising:
- a loft layer having a fleece layer and a reinforcing layer, the fleece layer being needle-punched to the reinforcing layer;
- a first polymeric layer bonded to the fleece layer;
- and a second polymeric layer bonded to the reinforcing layer, wherein at least one of the first polymeric layer and second polymeric layer comprises between about 40 wt % and 60 wt % of polyvinyl chloride, a plasticizer, and titanium dioxide, the single ply membrane having a thickness in a range of about 38 mm to about 50 mm.
A method of fabricating a single ply membrane comprising:
- providing a loft layer having a fleece layer and a reinforcing layer;
- the fleece layer being needle-punched to the reinforcing layer;
- securing a first polymeric layer to the fleece layer;
- and
- securing a second polymeric layer to the reinforcing layer, wherein at least one of the first polymeric layer and second polymeric layer comprises between about 40 wt % and 60 wt % of polyvinyl chloride, a plasticizer, and titanium dioxide, the single ply membrane having a thickness in the range of about 38 mm to about 50 mm.
A method of facilitating protecting a structure comprising:
- providing a single ply membrane having a loft layer having a fleece layer and a reinforcing layer, a first polymeric layersecured to the fleece layer, and a second polymeric layer secured to the reinforcing layer, the fleece layer being needle-punched to the reinforcing layer;
- wherein at least one of the first polymeric layer and second polymeric layer comprises between about 40 wt % and 60 wt % of polyvinyl chloride, a plasticizer, and titanium dioxide, the membrane having a thickness in range of about 38 mm to about 50 mm;
- and
- installing the single ply membrane on at least a portion of a roof of the structure.
