Commonly the imported grade of Canadian cedar is relatively free of knots resulting in a clean and contemporary appearance. It is available in many profiles and can be installed both horizontally and vertically. Compliant with BS EN 14915 and BS 8605-1; CE marked. PEFC certified on request.

Appearance:

Canadian western red cedar has a strong, distinctive grain. The colours vary widely from dark chocolate brown to light pink. The boards are relatively free of knots, giving a clean and contemporary appearance. When left untreated, cedar will bleach to a silver colour.
