Appearance
British western red cedar has a pink to amber colouring with frequent knots. The colouring of British cedar is paler, but more consistent, than its Canadian cousin.

Weathering
When left untreated, cedar will bleach to a silver patina. Because of its relative consistency, British cedar cladding weathers quite evenly. Northerly elevations may weather to a darker grey than those facing South

Desired service life
Occasionally wet 30 yrs. Frequently wet 15 yrs.

Movement class
Medium

Resistance to impact
Low

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

Density
330 – 390 Kg / m3

Extractives
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.

How to fix
Pre-drill and hand nail with stainless steel nails through the face or use a first fix nail gun. Only nail each board once per batten.
