Cavityrock Black is also available with the addition of a black mat fleece facer. It is designed to mask the insulation layer to create a crisp, black aesthetic in open-jointed cladding systems. Because it combines the insulation and facer in a single step, it can reduce installation time and material cost to achieve your desired design aesthetic. The fleece material has been designed for exposure to the elements (weather, heat, UV), while maintaining the thermal and acoustic performance and fire protection expected of stone wool. The fleece facer is chemically bonded to the insulation during the manufacturing process, offering improved mechanical properties and superior long-term performance.
