Plylap offers the stability of plywood and the natural beauty of wood. This horizontal lap siding is manufactured from APA-approved 303 siding panels so it won't swell or warp like hardboard or molded-fiber sidings. Each 8-foot length is rabbeted for the lap and back-kerfed to help reduce cupping. Tongue-and-groove ends (back-cut like on hardwood strip flooring) allow for tight butt joints and eliminate the need to locate joints over a structural member. Plylap is available in redwood, cedar, MDO, and douglas fir. For more information, contact Laco Lumber, Inc., P.O. box 1130, Woodland, CA 95685; 916/661-0812.
