Claims28
An article comprising:
- a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer,
- a first bituminous material layer comprising at least one of asphalt or tar,
- a film layer comprising at least one of a glue layer or a plastic layer, the film layer to be disposed between the first bituminous material layer and the first non-woven fabric layer, and the film layer to:
- form a bond between the first non-woven fabric layer and the first bituminous material layer, and
- reduce bleeding of the at least one of asphalt or tar from the first bituminous material layer to the first non-woven fabric layer,
- a second non-woven fabric layer,
- a woven fabric layer, and
- a second bituminous material layer;
- wherein the second bituminous layer has a surface to adhere to an exposed surface of a structural building.
