Abstract	When masonry walls were thick and the materials used quite porous, their very mass absorbed the rainwater and later released it. Eventually, though, walls became thinner and something had to be done to prevent rain penetration. That could be either a face-sealed wall, which in a sense is a rainwater barrier in the form of vinyl or aluminum cladding on the outside wall, or a cavity wall, which consists of one wall just to catch the rain and an adjacent cavity to serve as moisture break. With open rainscreen walls, which reflect current thinking in wall construction, the cladding constitutes the first line of defence. And then there is a second line of defence.
