Cavity Wall Insulation

Cavity Wall Insulation

If your home was built after 1920, there's a good chance that its external walls are made of two layers with a gap or cavity between them. Cavity Wall Insulation that gap.

It doesn't matter if you live in a 3 storey house, have normal or narrow (<50mm) cavities or need remedial works before insulating, Everwarm has a solution for you.

Benefits

Typically 35% of heat lost from a house escapes through uninsulated cavity walls. This can be reduced to around 10% by having cavity wall insulation installed.

On average you will save around £140 per year on energy bills and reduce your CO2 emmisions by 560kg/year (Energy Saving Trust figures, November 2013)

By insulating your cavity walls it will not only keep the warmth in to save energy, but it can also help reduce condensation inside the house if this is a problem on your external walls.

How it works

To insulate your cavity walls, our installation team will drill small holes around 22mm in size at regular intervals (around 1m) in the outside wall of your home. Using specially designed equipment, they then blow insulation into the cavity. Once all the insulation is in, our team fills the holes in the brickwork so you'll barely notice them.

Cavity wall insulation can be made out of three types of materials:

  • mineral wool

  • beads or granules

  • foamed insulants

All three are manufactured according to British standards. Foam Insulation systems should be certified by the British Board of Agrément and installed according to strict guidance laid out in the associated BBA Certificates.
