Your free guide to high performance insulation for better buildings.

Insulation is fundamental for energy efficiency because it resists the transfer of heat through the building envelope. The right insulation makes a building more comfortable, supports energy saving, and reduces operational carbon emissions. At Knauf Insulation, we’ve developed a full suite of products that you can rely on to deliver the thermal performance you need.

Reliable thermal performance

Our glasswool energy efficient insulation has been designed to meet or exceed regulatory requirements for energy efficiency. The material's flexibility allows it to adapt to minor surface imperfections, minimising gaps and maximising thermal performance.

Its flexible nature also means it’s easier to install correctly, compared with rigid foam products, so it’s less prone to unintentional gaps that can reduce thermal performance.

Glasswool insulation is suitable for a broad range of applications and helps your building to achieve its designed thermal performance.

Repaying our ‘carbon debt’ in just 95 days

We recognise that the manufacturing process creates unavoidable embodied carbon emissions. As well as aiming to reduce these as much as possible, we’re proud that it only takes 95 days from installation to offset the embodied carbon of our mineral wool insulation, through operational carbon reduction.
