American Red Cedar

Over the past few decades, Western Red Cedar Cladding has become one of the most popular external/internal claddings. Cedar cladding has rich and variable colours, a high resistance to decay and high durability from natural preservatives. Left unstained or unvarnished cedar cladding will turn silvery grey. Alternatively the cedar cladding can be stained with Sikkens or other products to maintain its rich colours.
