Western Red Cedar

Western Red Cedar is straight grained with a colour maturing down to a reddish-brown and, in time, to silver-grey – this weathered appearance sometimes sought-after by architects.

Description

Western Red Cedar is straight grained, rather coarse textured, with a prominent growth ring figure and non-resinous. The timber’s heartwood shows considerable colour variation when fresh, from a dark chocolate-brown to a salmon pink colour, perhaps variegated, maturing down to a reddish-brown and, in time, to silver-grey – this weathered appearance sometimes sought-after by architects. Weighs 370 kg/m3 (23 lb/ft3); specific gravity .37.


Properties

Western Red Cedar has low bending and crushing strength, with very low stiffness and resistance to shock loads. Steam bending classification is very poor.

Thin stock dries readily with little degrade, but thicker sizes tend to hold moisture at the centre and care is needed to avoid internal honeycombing and collapse. This is especially true of UK timber. There is small movement in service.

The timber is durable. Resistant to preservative treatment.

Main Uses

Glass house and shed construction, shingles, interior finishing, exterior boarding and cladding, beehive construction, poles, posts and fences.
