Description

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 our unique bio-based binder, ECOSE® Technology.

Benefits

  • Single slab can be used for multiple applications.
  • Tested to achieve up to 60 minutes fire resistance when used in the floor of a loft conversion.
  • Engineered to adapt to minor imperfections in the substrates and friction fits between studs, joists and rafters.
  • Enables existing ceilings to be retained on a loft upgrade whilst meeting building regulations.
  • Manufactured from mineral wool which provides the best levels of sound absorption and reduction compared to other mainstream insulants.
