Pitched roof insulation solutions

The thermal performance of the roof is fundamental to achieving an energy efficient building.

Knauf’s mineral wool insulation is flexible, so it can fit snugly between joists. It also ‘knits’ together where two edges meet.

Our loft roll products will recover their thickness when unwrapped, helping to fully fill the space between joists or rafters, and offcuts can be used to fill gaps around penetrations.

This flexible quality of mineral wool helps to reduce unwanted air gaps, reducing thermal bypass and maximising thermal performance.

Efficient, sustainable insulation solutions benefit installers, housebuilders, and homeowners.

Knauf Insulation’s combi-cut loft roll products come partially perforated, so they can be used between joists or uncut as a full-width roll, for a more efficient installation. Offcuts can be easily used to fill gaps, improving thermal performance and reducing waste.

Loft roll products for ceiling level insulation are also compression packed, expanding in thickness when unwrapped. This makes for easier transportation and reduces road miles.

Our glass mineral wool insulation is manufactured with ECOSE®, our unique plant-based binder that is low-carbon. This reduces the embodied carbon of the product and the building.
