Cavity & Internal Wall Insulation

Improve warmth, comfort and energy efficiency with our range of Cavity & Internal Wall Insulation, ideal for new builds, extensions and renovation projects. Wall insulation plays a key role in reducing heat loss and helping maintain a more consistent indoor temperature, making rooms more comfortable while supporting lower heating costs. Whether you’re insulating a cavity wall during construction or upgrading internal walls as part of a refurbishment, choosing the right insulation helps deliver long-lasting performance.

Cavity insulation is designed to fit between wall layers to reduce heat transfer and improve overall building efficiency. Internal wall insulation is ideal for stud walls, partition walls and lining systems, offering thermal improvement and, in many cases, added sound reduction between rooms. These products are widely used across domestic and commercial projects where better insulation and building performance are required.

For best results, select insulation suitable for the wall type and thickness, ensure boards or rolls fit snugly without gaps, and follow recommended guidance on vapour control and ventilation. Using compatible membranes and sealing products can also help improve results by reducing drafts and maintaining a clean install.
