Thermal insulation NYROCK® FRAME SLAB 032

NyRock® Frame Slab 032 is non-combustible thermal stone wool insulation for timber and steel frame studwork. NyRock Frame Slab 032 is a semi-rigid stone wool insulation slab designed specifically for use between the studwork of external timber or light gauge steel frame walls. NyRock Frame Slab 032 is manufactured using NyRock technology, a new, patented production process that makes a more efficient fibre structure which delivers the lowest lambda stone wool insulation currently available in the UK & Ireland.1 Research has shown that samples of ROCKWOOL stone wool insulation taken from an external wall system, maintained performance for a period of over 65 years. ROCKWOOL stone wool insulation is water repellent and non-hygroscopic, meaning it will not absorb water from the surrounding environment. It retains its thermal performance even in humid conditions, helping to support the durability of the building fabric. A vapour permeable membrane on the outside of the sheathing board is also necessary, this protects the timber frame from water penetration whilst allowing water vapour to escape. Again, enhanced thermal benefits are offered by reflective low emissivity membranes, where there is a clear air space of 20mm or more. The effect on the overall wall U-value can be seen in the tables.
