Combination flashing and drainage system
A combination through-wall masonry flashing/drainage device having a flashing membrane with at least one reinforcing cloth adhered to at least one side of the flashing membrane. A wicking cloth made of a synthetic wicking material is then adhered to the device. The wicking cloth material is selected for wicking ability, life expectancy, mildew resistance, and strength characteristics.
1. A combination through-wall masonry flashing/drainage device comprising:
a flashing membrane, the flashing membrane having a first side and a second side opposite the first side, the flashing membrane selected from the group consisting of polyvinyl chloride (PVC) flashing membrane, polyethylene flashing membrane, stainless steel sheet flashing membrane, a flashing membrane in conformance with ASTM standard D 1970-01, and a flashing membrane in conformance with ASTM standard D 6164-00;
a reinforcing cloth adhered to the flashing membrane first side; and
a wicking cloth adhered to the flashing membrane second side, whereby when installed between an inner wall and outer wall with the wicking cloth facing up, water between the inner wall and outer wall is drawn through a mortar joint at the base of the outer wall to the outside of the outer wall by the wicking action of the wicking cloth without the need for vents.
2. The device of claim 1 , wherein the wicking cloth is made of polyester.
3. The device of claim 1 , wherein the wicking cloth is made of polypropylene nylon.
4. The device of claim 1 , wherein the wicking cloth is made of polyethylene.
5. The device of claim 1 , wherein the flashing membrane is in conformance with at least one of ASTM standard D 6164-00 and ASTM standard D 1970-01, and wherein the reinforcing cloth is made of polyester.
6. A combination through-wall masonry flashing/drainage device comprising:
A flashing membrane, the flashing membrane having a first side and a second side opposite the first side, the flashing membrane selected from the group consisting of polyvinyl chloride (PVC) flashing membrane, polyethylene flashing membrane, stainless steel sheet flashing membrane, a flashing membrane in conformance with ASTM D 1970-01, and a flashing membrane in conformance with ASTM standard D 6164-00;
a first reinforcing cloth adhered to the flashing membrane first side;
a second reinforcing cloth adhered to the flashing membrane second side; and
a wicking cloth adhered to the second reinforcing cloth, whereby when installed between an inner wall and outer wall with the wicking cloth facing up, water between the inner wall and outer wall is drawn through a mortar joint at the base of the outer wall to the outside of the outer wall by the wicking action of the wicking cloth without the need for vents.
7. The device of claim 6 , wherein the wicking cloth is made of polyester.
8. The device of claim 6 , wherein the wicking cloth is made of polypropylene nylon.
9. The device of claim 6 , wherein the wicking cloth is made of polyethylene.
10. The device of claim 6 , wherein the flashing membrane is in conformance with at least one of ASTM standard D 6164-00 and ASTM standard D 1970-01, and wherein the first reinforcing cloth is made of polyester.
