Rocksilk Flexible Slab is a Rock Mineral Wool slab, designed for use in multiple thermal and acoustic applications as well as the fire protection of a loft conversion floor.
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.
- Multi-purpose product which can be used to insulate a wide range of applications on site.
- Flexible on all four sides for quick and simple installation.
- Existing ceilings can be retained on a loft upgrade whilst meeting building regulations.
- 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 structure in which it is incorporated.
- 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.
