Cavity Wall Insulation – Save Energy, Lower Bills & Keep Your Home Warm
What is cavity wall insulation?
Cavity wall insulation is an effective way to reduce heat loss from your home. By filling the gap (cavity) between your property’s external walls with specialist insulating material.
Not only does it help keep your home warmer in winter, but it can also keep your home cooler in summer by slowing the transfer of external heat through the walls, reducing heat entering the building.
Using advanced closed‑cell technology, the insulation prevents moisture absorption while delivering outstanding thermal performance – all without the need for ongoing maintenance.
