Tongue & Groove 11/16" - 2

This ornamental 11/16" - 2 v-groove siding measures .687" thickness, allowing any size width of four-quarter lumber for milling on an industrial moulder. The wide panels are for covering walls & ceilings, creating a beautiful architectural appeal. It consists of a 1/4" tall by 9/32" deep groove with a 1/8" forty-five-degree angle on the right edge. The opposite side retains the identical chamfer with a 1/4" high by 1/4" wide tongue. There is a built-in void of .010"; this space is for the expansion and contraction of the wood during seasonal changes in relative humidity. When two milled pieces of lumber join, they create a 1/4" wide by 1/8" deep v-groove where the boards meet.
