Quarrix ProTect Furring Strips provide long-lasting protection that prevents moisture damage within the walls. Uniquely designed with small air channels to allow bulk water and other moisture to easily escape behind cladding, and air to flow vertically and horizontally to keep the wall assembly dry. Made of durable, HDPE plastic, ProTect Furring Strips are resistant to warping, splitting, mold and mildew. Each piece is dimensionally die-cut so that you receive an identical piece every time. Approximately 1 linear foot of ProTect Furring Strips will be needed for every 1 square foot of wall covering.
