Cedar siding is derived from a renewable
resource. vcbcb
It grows from the earth, is harvested,
manufactured and used for decades or even
centuries. Then, when its useful life span
is ended, it returns to the earth.
This natural life cycle explains why real
cedar siding is the environmentally sound
choice when compared with alternative materials
like concrete, plastic or metal. Only wood
comes from a renewable, biodegradable resource.
Today's sustainable forestry practices ensure
a perpetual abundance of high-quality wood
from North America's forests. Aluminum and
concrete come from materials extracted from
the earth. Once removed, they can never
be replaced. Plastics are derived from dwindling
petroleum reserves.
Of each tree harvested, 95% goes into useful
products. The remaining 5%, the branches,
is left on the forest floor to biodegrade
into rich compost for the next crop.
Concerned about tomorrow? Cedar's on your
side.
