Fiberglass reinforced panels, or FRP, are thin, flexible plastic panels made of strong polyester resin reinforced with fiberglass. They are used on walls and ceilings and can be installed directly over drywall, wood, concrete block, and many other solid surfaces. FRP systems include plastic trim molding to create a continuous durable, scratch-resistant surface that is easy to clean and mold- and stain-resistant. The panels can even be hosed down for cleaning. All of these qualities make FRP an excellent material for covering walls and ceilings in restaurant kitchens, public bathrooms, medical facilities, food processing areas, and many other environments requiring frequent deep-cleaning.
