WP 305 Tongue & Groove 2-1/2"

This 2-1/2" WP 305 tongue & groove decking measures 2.500" thickness, requiring twelve-quarter lumber for milling. Widths are machined to any desired size within the parameters of the molder or shaper used to mill the design. The dual-purpose pattern is mainly used for decking material but could also be used in roofing applications with the v-joint facing the room below. The profile is composed of two 7/16" tall by 3/8" deep grooves and two 5/16" wide by 3/8" tall tongues with a 1/4" wide by 3/16" deep bevel on one edge. There is a 1/16" void in the joint area for expansion and contraction of the lumber during seasonal changes in relative humidity; this will also aid during the installation process. When two milled planks are joined, they create a 1/2" wide by 3/16" deep v-joint between the merged boards.
