Claims30
An article comprising:
- a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material 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.
An article comprising:
- a water resistant underlayment portion, wherein at least a strip of the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material 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.
An article comprising:
- a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material layer, a second non-woven fabric layer, a woven fabric layer, a second bituminous material layer, and a removable cellophane layer to cover a surface of the second bituminous layer;
- wherein the cellophane layer is a double release strip to selectively remove two non-contiguous portions of the cellophane layer from the second bituminous layer.
An article comprising:
- a water resistant underlayment portion, wherein at least a portion of a surface of the water resistant underlayment portion includes a strip consisting essentially of:
- a first bituminous material layer, a 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.
An article comprising:
- a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material layer, a woven fabric layer, and a second bituminous material layer;
- wherein the second bituminous layer comprises a surface to adhere to an exposed surface of a structural building.
An article comprising:
- a water resistant underlayment portion, wherein at least a strip of the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material 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.
An article comprising:
- a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:
- a first non-woven fabric layer, a film layer, a first bituminous material layer, a second non-woven fabric layer, a fiberglass mesh 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.
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 film layer, a first bituminous material layer, a second non-woven fabric layer, a woven fabric layer, a second bituminous material layer, a third non-woven fabric layer, a second film layer, a third bituminous material layer;
- wherein the third bituminous layer has a surface to adhere to an exposed surface of a structural building.
