sidings are normally supplied in a variety
of patterns either green (unseasoned) or dry

Channel siding is a popular type of lap
siding and is used whenever a rustic appearance
is desired. A
versatile siding, it can be installed
vertically, horizontally or diagonally.
In channel siding the profile of each board
partially overlaps that of the board next
to it creating a channel that gives shadow
line effects, provides excellent weather
protection and allows for dimensional movement.
Channel siding is normally supplied in
unseasoned knotty grades. The face side
is saw textured. Commonly available sizes
are 1 x 6 in., 1 x 8 in. and 1 x 10 in.
Clear grades are manufactured to order.
