Channel Rustic Lap Siding traditionally has 1/2” overlap and a 1” to 1 1/4” inch "reveal" - that when installed creates a channel effect between siding boards.


Channel siding installs with a minimal amount of effort and material wastage. The Channel pattern is traditionally installed horizontally with the edge of one board having a recessed area along its rear which receives the shaped top-rear edge of the board next to or below it, so as to exclude water during rainfall.
Channel Lap Siding is normally supplied in partially seasoned (PAD) knotty grades with a rough saw textured face. Commonly available sizes are 1x6", 1 x 8" and 1 x 10". Clear grades are milled and priced to order.


Lately we are seeing more channel lap vertical applications. This is a variant on the new "Shadaw Gap" narrow 1/4" shadow line profile that is popular now.
If you choose to install channel siding vertically be sure to bevel cut the ends and install so water is directed to the outside.

The Channel Rustic pattern provides excellent weather protection and allows for maximum dimensional wood change (breathing) in climates of highly variable moisture levels between seasons - without adversely affecting the appearance of your channel lap siding.
Installers usually leave an 1/8” air gap between boards to allow the wood to expand and contract with the seasonal humidity.
