Named for the nearby Cascades mountain range and made from the Pacific Northwest's regional Red alder, Cascades Cladding is comprised of three thicknesses in a tongue and groove profile. With rounded edges and a silky smooth face, the cladding is available in 10 translucent colors which allow the natural features to shine through. Two low-VOC finishes are offered- satin which enlivens the wood and dead flat which protects the wood with near invisibility. Designed with tongue and groove edges for easy installation with standard tools and techniques. Dimensions 7/16", 5/8" and 3/4" thick x 3-1/2" wide in random lengths of 2'-6'.
