Stay Warm & Energy-efficient
Internal wall insulation cuts energy costs significantly
Internal wall insulation is installed on the interior side of your walls, effectively preventing heat from escaping—an excellent solution for homes unsuitable for cavity wall insulation.
For solid-walled homes, often built before the 1920s without cavities, you can choose to either insulate internal walls or opt for external wall insulation.
Insulating internal walls creates a strong thermal barrier between the inside and outside, significantly reducing heat loss and improving energy efficiency.
Installing insulation for internal walls could save you up to £930* annually on energy bills.
