How will I know if my property is suitable for cavity wall insulation?
If your property was built between 1932 and 1982 then you are likely to have cavity walls. If the thickness of your wall is greater than 11 inches then the likelihood of the property having a cavity is high.
Is cavity wall insulation work guaranteed?
Yes, our cavity wall insulation has a 25 year guarantee.How is cavity wall insulation installed?
The insulation is blown in through the holes made in the wall, which are no bigger than 18mm to 25mm. The holes are then filled in afterwards and matched to the existing appearance of your wall. It's all done from the outside, so it will not affect the appearance of the inside of your home.
