Properties
of Cedar
- Cedar is a
lightweight and dimensionally stable wood that lies flat and stays
straight, which means it resists the natural tendency to warp and
crack as you might find in many other wood species. Its distinct
cell structure discourages moisture rot by allowing it to dry out
faster than outdoor furniture made from tropical hardwoods.
- Cedar's cellular
structure creates interior air spaces that give it an insulation
value higher than most woods, giving it a very high thermal coefficient.
In plain English, that means that even on the hottest days, it is
cool to sit on.
- Cedar fibers
contain oils that act as natural preservatives to help the wood
resist rot and decay making it excellent furniture material for
moist or humid climates. These properties also make Cedar a very
popular material for pool, hot tub and sauna areas, as well as kitchens
and baths. Indoors or outdoors, cedar can be left unfinished
to weather to a silvery grey over time.
- Among other
things these naturally occurring organic compounds called (thujaplicins)
give off that distinct cedar aroma that is pleasant to humans but
a deterrent to insects, moths and other wood pests - an added plus
for outdoor furniture!
- Cedar is free
of pitch and resin, so you can enjoy the wonderful aroma without
worrying about getting pitch, sap or resin on your clothes, skin
or other furnishings.

Aside from
being the choice material for picnic tables and outdoor patio
and garden furniture, Cedar is the preferred material for all
outdoor applications that seek visual harmony with the landscape
combined with stability and durability. Indoors, cedar's
dimensional stability makes it perfectly suited to a variety of
uses in high moisture areas such as kitchens, bathrooms and saunas.
Advantages
of using Cedar for outdoor furniture
Unlike plastic
or resin furniture, cedar will not bow, sag or get brittle over time,
and it won't blow across your yard. It is heavy enough to stand
up to all but the strongest winds, yet lighter than most other wood
so it is easy to move when you need to.
White Cedar will last 25-30 years unfinished. There is no need
to treat the wood, because it is naturally resistant to rot and pests.
However, some people like a little color; for that it is recommended
that you stain the product (rather than paint it) in order to retain
the natural protection of cedar (if you must paint, use latex paint
to allow the wood to breathe). Your cedar furniture will hold
its handsome appearance year after year with very little maintenance.
Leave it unfinished to weather naturally to a silvery grey, or stain
it to maintain a consistent color from year to year. To make
your cedar furniture last even longer, cover it or bring it inside
for winter, and do not let it sit in mud or water for long periods
of time.

Cedar products are an all around safer, healthier, natural alternative
for patio furniture and outdoor dining sets than other wood materials
that have been treated with chemical preservatives. Read on
for more about the dangers of chemically treated wood.
Cedar is
a safe, natural alternative to chemically treated wood
Much of today's
outdoor furniture consists of (chemically) pressure treated materials.
These materials hold up outdoors because they are soaked in a toxic
stew of chemical preservatives that are strong enough to require warning
labels for those who handle it. The three primary ingredients
in pressure-treated woods are: copper, chromium and arsenic (CCA).
A controversy
exists on the extent of arsenic exposure due to physical contact with
CCA wood surfaces. Such surfaces include playground equipment,
decks and picnic tables built using CCA treated wood. Studies
have shown that virtually no inorganic arsenic is absorbed through
the skin, but is readily taken up by ingestion. Thus, the potential
exposure is hand to mouth, and therefore, children are considered
the most vulnerable to this potential risk. (Contact your local
Environmental Department for more information.)
About White
Cedar log furniture
It's normal for all cedar log furniture to endure the natural process
of checking as the wood "seasons". Checking occurs
as a wooden log releases moisture across or through the annual growth
rings. It does not affect the structural performance or integrity
of the wood. All logs which contain the heart of the tree will
develop lengthwise cracks or checks. The check never goes deeper than
the heart.
Since moisture is a factor in the checking process, the depth and
span of the checks will vary upon placement outdoors. Direct sunshine
contributes to the drying of logs, therefore widening their cracks.
Moisture and indirect light will shrink cracks. You can expect
your log furniture to change with the seasons, indoors or out.
