Cavity Wall Insulation

Cavity Wall Insulation is one of the most common methods of insulating the home. Since 1985 cavity walls were commonly insulated when the house was built, however any homes built before this date may have partially insulated or uninsulated cavities. This means that up to 35% of the heat in your home is being lost through your walls.

It is a relatively quick and free* measure to install, meaning it has a very quick payback time (the time it takes for the savings in your energy bills to effectively pay for the measure itself).

*subject to funding availability

Bonded Bead Insulation

For cavity wall installations, Thrift Energy uses an oil-based, waterproof polystyrene bead, which is bonded with a glue when being injected into the cavity. This creates a material that is solid, yet has gaps for any water that may get into the cavity to drain down to the bottom of the cavity as was intended, rather than being transferred across to the internal walls. We have completed thousands of cavity wall installations with our bonded bead without any complaints of damp.

All of our installations come with a 25 year, insurance-backed guarantee.

With around 35% of all heat loss occurring through the walls, a properly insulated cavity can save an average house up to £210 a year!
