Canadian Western Red Cedar T&G Cladding Board 144mm x 19mm

Western Red Cedar Tongue & Groove (T&G) cladding is a premium, high-performance choice for exterior applications, offering the perfect balance of natural beauty, durability, and long-lasting structural stability.

Sourced from FSC-certified sustainable forests, this timber is naturally resistant to rot, decay, and insectsmaking it an ideal material for exposed outdoor environments. Its low density and lightweight composition make it easy to handle and install, while its exceptional dimensional stability helps prevent warping, shrinking, or swelling over time.

The fine, straight grain and rich reddish tones give this cladding a timeless, architectural appearance. Left untreated, it gracefully weathers to a refined silver-grey patina. For those wishing to preserve the cedars warm colouring, a UV-protective oil such as OSMO is highly recommended.

The Tongue & Groove profile provides a clean, seamless interlock for enhanced weather resistance and a modern, uniform finish. Whether you’re cladding a home, garden room, extension, or commercial building, Western Red Cedar remains one of the most respected choices among architects, builders, and designers.
