Drainage Mat DC14



DC14 Drainage Mat was designed following rain screen principles to allow ample space for drainage and drying between exterior wall cladding and wall sheathing. With drainage channels on both sides, it permits easy drainage for water and allows air movement between the cladding and sheathing to help keep the wall dry. It is ideal behind exterior claddings that are closely attached to the wall sheathing, such as traditional stucco, stone, thin brick veneer, and siding. Because DC14 is made of extruded polystyrene (XPS), it does not absorb moisture and is not a food source for mold.
