Panel 15® is a composite panel for exterior use made by laminating a textured aluminum skin to a substrate of exterior grade douglas fir plywood. A fiberglass reinforced kraft/foil scrim backer is added for panel balance and acts as a moisture barrier. Panels are furnished with a strippable film (or interleafed microfoam) on the painted surfaces to protect the finish during shipment and installation. The panel is mechanically fastened to the substrate (or wood/metal studs) and the system is completed using trim moldings (one and two piece aluminum extruded moldings) with various profile options.
