If there is wood behind the Styrofoam to drive screws into, then the panels can be installed over this material. If installing on the exterior over any surface that is not concrete. or metal, we also recommend a drainage mat. Our panels are adhered with a glue and screw method. The installation instructions are found here for our Regal Chiseled panels.
