Designed for use with exterior stone, stucco, brick cedar or fiber cement siding, Ultra Drain Mat is an easy to install rainscreen system that provides effective drainage and ventilation. It keeps moisture from entering the wall system through mortar joints, gaps or cracks in the cladding material, and via the edges of wood or fiber cement board. The product creates a continuous capillary break and channel for moisture to drain and also accelerates drying of the exterior cladding. It is available in 1/4-inch or .40-inch thicknesses.
