Building More Efficiently

Thanks to cavity wall insulation for new-build properties, bricklayers no longer need to install insulation during construction. Blowing Supafil Cavity XL into the cavity wall makes the building process much more efficient. An increasing number of contractors are choosing Supafil Cavity XL for new-build projects because it delivers greater comfort for occupants and professional users while making a significant contribution to energy efficiency and environmental sustainability.

Supafil Cavity XL

Knauf Supafil Cavity XL is a glass mineral wool insulation specifically developed for insulating new cavity walls. The water-repellent glass wool fibres are designed to completely fill the cavity thanks to their high installed density. This allows significantly higher insulation performance to be achieved compared with traditional insulation systems that rely on a residual air cavity.

Seamless Insulation

Nothing performs better than seamless insulation. A layer of sprayed polyurethane foam applied to the inner wall creates outstanding thermal insulation without joints or gaps, resulting in an airtight building envelope. Our experienced and fully trained installers ensure your building is insulated professionally and to the highest standards, giving you complete peace of mind.

Lower Energy Costs, Greater Comfort – Even in New-Build Homes

For occupants, high-quality building insulation not only reduces energy costs and improves living comfort, but also makes a valuable contribution to environmental sustainability.
