Norwegian manufacturer Fibo Group has launched a new series of its waterproof interlocking wall panel system. Panels consist of a plywood core faced with a decorative high-pressure laminate; the long sides have a proprietary tongue-and-groove construction for locking the panels together. According to the manufacturer, the Fibo system does not require a water vapor barrier or waterproof membrane behind the panels and can withstand both direct water exposure and large temperature fluctuations. Each panel measures 23.62 by 15.74 inches and may be directly mounted onto wood or steel studs, over existing walls, or over ceramic tiles. Contact a local distributor for pricing.
