Glass Mineral Wool


FrameTherm® Roll 32 is a Glass Mineral Wool roll, designed for use in timber frame applications between studwork, that offers the best thermal performance in the range.

It is non-combustible insulation with the best possible Euroclass A1 reaction to fire classification, and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.


  • Designed to friction fit between timber studs, which prevents air movement and infiltration through or around the insulation, minimising heat loss.
  • Ready-cut to allow quick and simple installation, maximising on-site efficiency when compared with alternative insulants.
  • Rolls are fully cut into 2x570mm and 3x380mm to suit commonly used timber stud spacing.
