Cavity wall insulation

Cavity wall insulation

Homes built after 1920 are more likely to have wall cavities, which is a gap between two layers. Insulation will fill this gap, reducing heat loss and effectively cutting your annual energy bills.

How much will I save with wall cavity insulation?

With wall cavity insulation you have a cheap way to insulate your home and reduce your energy bills.

With cavity insulation you’ll make savings on your household bills and your carbon dioxide emissions. This means you’ll be financially better off, whilst helping the environment with global warming issues.

Having wall insulation installed will save you up to £135 every year and considering costs are between £100 and £350, payback is as little as three years. This will help many homes escape fuel poverty, which is classified as spending 10% or more of income on dual fuel bills.

On top of this financial saving you’ll also see a major carbon saving, reducing your home’s footprint. As much as 550kg of carbon emissions can be cut every year with the simple installation of cavity insulation.

Is my home suitable for cavity insulation?

Cavity wall insulation is likely to be suitable for your home if:

  • The cavity in your walls is at least 50mm in width

  • The brickwork of your walls remains in good condition

  • The property is over 10-years-old

  • The external walls have unfilled cavities

How is wall cavity insulation installed?

When wall insulation for the cavities is installed, small holes are drilled into the wall at intervals. Insulation is then blown into the cavity with special equipment until the gap has been filled, and the holes are refilled.

This isn’t something that can be done with DIY and a registered, professional installer will be needed. The job takes roughly two hours for a trained installer, so it’s a simple and quick method with no mess left behind.
