This 1-1/2" - 13 radius edge roof decking measures 1.500" thickness; widths can be adjusted to any desired size within the parameters of the moulder used to mill the pattern. When two milled boards are joined together, they create a 1/4" wide by 1/8" deep radius vee groove on one face side of the lumber. The profile consists of a 1/2" wide by 3/8" deep tongue and groove, with a 1/8" radius edge on one side edge of the pattern. There is a .053" void built into the joint area for expansion and contraction of the lumber during seasonal changes in relative humidity.
