A Rock Mineral Wool slab, designed for use in multiple applications, or for fabricators where mechanical characteristics and thermal performance are key.
Rocksilk® RS80 is a Rock Mineral Wool slab, designed for use in multiple applications, or for fabricators where mechanical characteristics and thermal performance are key.
Rocksilk® Building Slabs are multi-application products for use in built-up metal roofs and walls, pitched roof constructions between rafters, intermediate floors, separating floors, internal stud partitions and light steel frame infill. Rocksilk® Building Slabs are used extensively in OEM applications for fabrication of thermal, acoustic and fire products.
A Rock Mineral Wool slab, designed for use in multiple applications, or for fabricators where mechanical characteristics and thermal performance are key.
It is non-combustible with the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
Features and benefits:
Certification
Durability
Rocksilk® Building Slabs are odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. The product will have a life equivalent to that of the wall structure in which it is incorporated.
Standards and certification
Rocksilk® Building Slabs are manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by TÜV Nord.
Real performance
Glass and Rock Mineral Wool are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
Environmental
Rocksilk® Building Slabs contain no ozone-depleting substances or greenhouse gases. For further environmental information consult the relevant Environmental Product Declaration, available on the Knauf website.
Handling and storage
Rocksilk® Building Slabs are easy to handle and install, being lightweight and easily cut to size, where necessary.
