Cavity wall insulation

Cavity wall insulation plays a key role in energy efficiency for both new builds and refurbishments. Installed in the gap between external and internal walls, it helps to retain heat, lower energy bills, and reduce carbon emissions. Traditionally, cavity walls were left uninsulated to prevent damp, but modern insulation materials have improved moisture control, making them a reliable way to boost thermal performance. Whether you’re working on a residential or commercial project, the right wall insulation can make a significant difference in meeting building regulations and improving property value.

There are several types of cavity wall insulation available, including mineral wool, expanded polystyrene, and rigid foam boards, each suited to different construction needs. The cost of cavity wall insulation varies depending on the material, project size, and installation method. For builders looking to balance budget and performance, comparing options is essential.
