Insulclad® is a lightweight crack resistant cladding system made by Nuplex Construction Products. The system uses prefabricated sheets and architectural mouldings made from expanded polystyrene. These are attached to timber or steel framing or over existing exterior walls. The cladding is then coated with a glass fibre mesh and topped with an acrylic modified plaster.
The system is extremely light and easy to handle yet quite tough when installation is complete. Apart from the aesthetic and weatherproof benefits of Insulclad, it provides full insulation.
