Sto DrainScreen Drainage mat

Sto DrainScreen is a drainage mat between the cladding and the StoGuard seamless waterproof air barrier. Should water reach the back of the cladding it can drain from the wall assembly via the drainage mat, which also helps speed the drying of moisture-laden air (water vapor) that can accumulate in the wall assembly. Drainage and drying can be particularly important in hot and humid climates and in areas witth wind-driven rain.
