Moisture Content
Supplied ‘Green’ wet, we recommend drying the timber before installation, if you are using the cedar internally then it will need to be acclimatised for at least a week inside before installation. Cedar dries rapidly once the boards are separated from the pack, they will need warmth and air circulation to dry effectively. Boards should be stacked flat and evenly supported during drying.

Western Red Cedar is sourced from the Pacific Northwest from Northern California to Alaska. This specie is classed as a Softwood but has very good durability due to a natural oil in it making it perfect for exterior applications. The timber machines well is stable and easy to work with.

Ranges from light golden colour to mid to dark brown, some boards have a slight tint of red

Stainless steel nails must be used on Western Red Cedar to stop staining. Use of regular nails will over time result in black streaks running down the timber caused by the iron in the nail reacting with chemicals in the cedar.
