 About Canadian
Western Red Cedar |
|
 Thuja
Plicata, commonly known as Western Red Cedar, is
found mainly in Canada's Pacific Northwest. Renowned
for its natural beauty and outstanding physical
properties. |
|
|
Beauty |
|
 Western
Red Cedar has a uniform and fine-grained texture
combined with a palette of warm, mellow tones ranging
from light amber to deep honey brown. Its rich color
is beautifully complimented by a natural satin luster
no man-made material can duplicate. Adding another
dimension to its beauty is its unique fragrance.
Its subtle aroma and genuine beauty give Western
Red Cedar a universal appeal unsurpassed
by other softwoods. |
|
|
Durability |
|
Western Red Cedar produces
natural oil and extractives that act as preservatives
to protect the wood from insect attacks and decay-causing
fungi. Its ability to produce such preservatives
increases with age, allowing the wood to withstand
years of usage in sound condition. In addition,
Western Red Cedar is a dimensionally stable
wood that lies flat and stays straight. Compared
to other common woods, it boasts very low shrinkage
value, which makes it suitable for a variety of
uses in high-moisture areas such as saunas. |
|
|
Practicality |
|
Beauty aside, the Western Red Cedar's
cellular structure creates interior air spaces that
give it an insulation value higher than most woods.
Buildings, which feature cedar paneling, ceiling,
or siding, tend to stay warmer in the winter.
