Western Red Cedar (Thuja plicata)
General Characteristics
Western Red Cedar is coniferous softwood native to the
Pacific Northwest areas of North America and is a member
of the Cypress family. The heartwood is reddish or pinkish
brown to dull brown and the sapwood is almost white.
Wood Structure
The wood is generally straight grained and has a uniform
but course texture.
Wood Properties
Western Red Cedar is comparatively soft and light in weight.
It has low overall strength but when dry, is a dimensionally
stable wood. Movement in service is rated as small.
Western Red Cedar is an excellent thermal insulator and
has a low conductivity value.
Western Red Cedar has a low flame spread rating and resists
the spread of fire.
Because of its low density, Western Red Cedar has excellent
acoustical properties.
The durability of Western Red Cedar heartwood is legendary
and the heartwood is very decay resistant.
Working Properties
Western Red Cedar works well with both hand tools and
machine operations. Although it has a tendency to splinter,
it saws and planes well and it takes both stains and paint
satisfactorily.
