Here's What Happens To Unprotected Wood...
The
damaging effects of weather to unprotected wood begins immediately.
Rain, melting snow, and morning dew are quickly absorbed by unprotected
wood causing it to soften and swell. The sun's heat caused drying which
makes the wood shrink. These cycles of wet and dry, swelling and shrinking,
cause wood to warp, split, crack and check-all of which lead to premature
wood life and expensive repairs. Unprotected wood is also subject to
mildew and algae growth, rot and decay, surface graying and degradation
from Ultra Violet (U.V.) rays from the sun, and insect attack from a
variety of sources.
