GreenGuard DC14 Drainage Mat

With drainage channels on both sides, it permits easy drainage for water and allows air movement between the siding and sheathing to help keep the wall dry. Because DC14 is made of extruded polystyrene (XPS), it brings rainscreen protection and R-1 continuous insulation to your walls. It is highly moisture resistant and is not a food source for mold. The board is effective with fiber cement, wood, and foam-backed vinyl. It is ideal for drainage and drying behind stucco and stone veneers.
