Natural look of wood
If the natural look of wood is a priority, use cedar. The heartwood of the tree (the deeper colored red part, not the white sap part) is rot resistant.
Western Red Cedar is ideal for siding as it has a fine-grain fiber. There are various profiles to complement any architectural style. Western Red Cedar projects prestige with an enduring beauty. It's naturally durable with excellent dimensional stability for both exterior and interior designs.
Cedar doesn’t readily absorb moisture – and, since moisture is what creates twisting and splitting, cedar siding tends to lie flush and straight. Western Red Cedar siding has unique, natural performance characteristics and exceptional beauty that bring warmth, character, and longevity to siding projects.
