What is Cavity Wall Insulation?

Cavity Wall Insulation fills the gap between your walls to retain heat and reduce energy loss. It lowers heating costs and improves energy efficiency. A simple way to keep your home warm and save money!

Is cavity wall insulation suitable for all homes?

It works best for homes with unfilled cavity walls built after the 1920s

Do I need cavity wall insulation?

If your home was built after the 1920s, it probably has cavity walls, and unless constructed in the last two decades, these wall gaps may be unfilled. Utilizing cavity wall insulation is a budget-friendly approach to preserving heat, potentially reducing energy expenses. About one-third of heat loss in homes happens through walls, and cavity wall insulation could yield annual savings of up to £160 on heating bills.
