Can Duramax PVC panels be installed over drywall/brick/concrete/FRP?

Yes, Duramax PVC Panels can be installed over existing drywall, FRP, brick, or concrete, provided the underlying surface is sound, flat, and dry.

Over Drywall or FRP: Fasten the panels directly through the existing drywall or FRP into the underlying wall studs using #8 or #10 stainless steel or corrosion-resistant truss-head or pan-head screws.
Over Brick or Concrete: Install wood or metal furring strips across the masonry surface first using masonry anchors, then fasten the PVC panels directly to the furring strips. Furring strips create a level mounting plane and allow proper screw engagement.

Regardless of the substrate, always place fasteners in the center of the pre-punched flange slots and leave a 1/16-inch gap beneath the screw head to allow for natural thermal expansion and contraction.

Duramax PVC Panels vs FRP – Key Advantages

No Mold, No Rot: Unlike FRP, Duramax PVC Panels won’t support mold or mildew growth.
Easy Installation: Interlocking design means no backer boards, no glue, and no extra labor.
100% Waterproof: PVC panels are completely water-resistant, ideal for high-moisture areas.
Low Maintenance: No peeling, bubbling, or cracking—just wipe clean with ease.
Cost-Effective Over Time: No need for replacement or repainting like with FRP.
