90mm Knauf FrameTherm Roll 32 Glass Mineral Wool

90mm Knauf FrameTherm Roll 32 is a glass mineral wool roll designed for timber frame construction where it fits snugly between studwork. With thermal conductivity between 0.032 W/mK and 0.040 W/mK, this 90mm insulation roll delivers excellent performance. It's non-combustible and achieves the highest Euroclass A1 fire rating, thanks to our ECOSE® Technology bio-based binder.

Advantages

• Designed to friction fit between timber studs, stopping air movement and draughts through or around the material, significantly reducing thermal loss.
• Pre-cut rolls come in 2x570mm or 3x380mm widths to suit standard timber stud spacings.
• Made from mineral wool, delivering outstanding sound absorption and noise reduction performance compared to many other common insulation options.

Application

This 90mm Knauf FrameTherm 32 Roll suits insulating external walls and warm pitched roofs in timber frame buildings. Timber frame walls generally provide better thermal resistance than equivalent masonry constructions. However, their lighter mass means insulation materials must deliver stronger acoustic properties to compensate. This 90mm FrameTherm roll friction fits between studs to minimise heat loss whilst also providing acoustic absorption, boosting the wall's overall sound performance.

Real Performance

Glass and rock mineral wool installs more easily than rigid board alternatives. They adapt to minor substrate variations and lock together seamlessly, eliminating air pockets. 90mm Mineral wool insulation accommodates substrate irregularities and handles settling or movement throughout the building's life, maintaining close contact and consistent thermal performance. Avoiding air gaps is essential for genuine in-situ performance. Any insulation failing to deliver real 'as-built' thermal performance misses its core purpose and creates unnecessary risk as the sector works to close the performance gap.
