Treatment Untreated, Western Red Cedar is naturally rot resistant. While untreated Western Red Cedar is naturally resistant to rot, we highly recommend using OSMO stain to preserve its colour and protect against weathering, cracking, and expansion. Staining enhances the cedar’s durability, ensuring it maintains its appearance and integrity over time.

Board Run

It's important to tell us which way your cladding will be running as depending on the desired orientation of your cladding, the timber needs to be cut differently.

Vertical run cladding naturally channels water downwards, however if cut incorrectly horizontal profile boards may trap water inside the shadow gaps, making it more susceptible to weather-related issues like rot. To combat this, horizontal boards are cut with a slight angle in the gaps to help the water run off, while vertical boards retain a nice crisp edge.
