Cavity Wall Insulation
What are Cavity Walls?
Cavity wall insulation is the filling of the gap between the two skins of masonry forming the external wall and internal wall with an impervious or self draining insulation material.
How do I know if I’ve got Cavity Walls?
If your home was built after the 1920s it is likely that you have Cavity Walls, but if you want to check then there are two easy ways to tell:
- The brick pattern: in Cavity Walls, all the bricks on the outside will be lengthways, whereas for solid walls they are alternate lengthways-sideways-lengthways-sideways.
- The thickness of the wall: if you measure the depth of the wall at a doorway or window, a Cavity Wall will normally be about 260mm (10.25in).
Why have cavity wall insulation?
✔ With an uninsulated cavity, heat can easily escape meaning it requires more fuel to maintain a comfortable temperature
✔ External walls account for 35% of heat loss from the average house
✔ Installation is quick, easy and hassle free for you
✔ Each installation is covered by an independent 25 year CIGA guarantee
✔ On average, the installation takes no longer than a day to carry out
✔ The Government regards cavity wall insulation as one of the most effective energy savings measures to carry out
Grant Funding
