Abstract

A combination through-wall masonry flashing and drainage device has a flashing membrane made of stainless steel sheet and a reinforcing cloth affixed to a first side of the flashing membrane. The flashing membrane has a thickness between 0.001 and 0.007 inch. When installed between an inner wall and an outer wall, water between the inner wall and outer wall is diverted to the outside of the outer wall by the through-wall masonry flashing and drainage device.

Claims (15)

1. A through-wall masonry flashing and drainage device consisting of:

a flashing membrane made of stainless steel sheet, the flashing membrane having a thickness between 0.001 and 0.007 inch;

a reinforcing cloth affixed to a first side of the flashing membrane and forming a through-wall masonry flashing and drainage device in a continuous roll form; and

an adhesive disposed between the flashing membrane and the reinforcing cloth.

2. The device of claim 1 , wherein the stainless steel sheet has a thickness between about 0.0015 inch and about 0.003 inch.

3. The device of claim 1 , wherein the stainless steel sheet has a thickness of about 0.002 inch.

4. The device of claim 1 , wherein the stainless steel sheet is selected from the group consisting of type 302, type 304, and type 316 stainless steel.

5. The device of claim 1 , wherein the reinforcing cloth is a synthetic material.

6. The device of claim 1 , wherein the reinforcing cloth is selected from the group consisting of polyethylene, polypropylene, paper, fiberglass, and plastic.

7. The device of claim 1 , wherein the reinforcing cloth is woven.

8. The device of claim 1 , wherein the reinforcing cloth is a mesh.

9. The device of claim 1 , wherein the reinforcing cloth has a thickness of about 0.001 inch to about 0.20 inch.

10. The device of claim 1 , wherein the adhesive is selected from the group consisting of an acrylic adhesive and a latex adhesive.

11. The device of claim 10 , wherein the adhesive is selected from the group consisting of a hot-melt adhesive and a reactive hot-melt adhesive.

12. The device of claim 1 , wherein the reinforcing cloth is capable of absorbing moisture and wherein capillary action of the reinforcing cloth transmits water from a cavity defined between an inner wall and an outer wall of a structure to a location outside the structure.
