Duraclad™ interlocking wall and ceiling liner panels feature a multiwall structure that results in a high level of rigidity and strength, and allows for rapid installation. Interlocking tongue & groove edges permit fasteners to be completely hidden, resulting in a clean, smooth finish. Use it for interior cladding for all types. Duraclad's resistance to chemicals allows for frequent cleaning and sanitary maintenance, as well as extended service in harsh chemical environments.
