Canadian Western Red Cedar Cladding Features

Canadian western red cedar is the most popular choice for timber cladding projects in this country because the wood is clean and beautiful as well as being more durable and stable than most other wood species commonly used for cladding.
Canadian cedar is an ideal choice for modern designs where a relatively knot free appearance is desired and for applications where stability is a concern, such as screening.
Canadian western red cedar cladding grows more slowly than our native cedar, resulting in a denser and darker wood; however, it is also considerably more expensive.

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 although the process can be inconsistent and patchy. Northerly elevations may weather to a darker grey than those facing South.

Desired service life
Occasionally wet 60 yrs. Frequently wet 30 yrs.

Movement class

Resistance to impact

Working properties
Good workability. Takes fixings satisfactorily. Cedar is soft and relatively brittle which can result in bruising and splintering. No pre-drilling necessary.

330 – 390 Kg / Cm3

Western red cedar contains reactive oils, which will corrode ferrous metals. All fixings used in conjunction with western red cedar must be stainless steel. The brown oil can leave unsightly brown stains on the surface of the cladding and will stain any porous materials below the cladding. The reactivity of the oil makes western red cedar cladding unsuitable for polluted areas and shaded areas


How to fix
Hand nail with stainless steel nails through the face or through the tongue on suitable profiles.

Alternatively use a second fix nail gun and insert two nail per batten at opposing angles. For more information, visit the resource centre

Batten type
Treated softwood. 35mm thick x 50mm wide

Batten spacing
400 – 600mm 

Nail type
Stainless steel only. 50mm ring shank nails for hand nailing or 50mm second fix brad nails if using a gun. Trim head stainless steel screws are also suitable.

When to fix
Year round. Very stable in all conditions.
