Cavity Wall insulation made simple (and free!)

It is likely that you will need cavity wall insulation if your home was built between 1924 and 1982. Houses in this period were built with a cavity between two layers to help rainwater penetrate, however heat escapes easily here. Click here.

Do you have a cavity wall?

Knowing if your property has cavity walls is simple. Cavity walls will typically have full brick lengths visible with a cavity between two layers. This is where the insulation will be installed. Contact us for free insulation.

However, a property without cavity walls will have combinations of brick ends and lengths. This wall type isn’t suitable for insulation as there is no space to inject into.

How do you insulate cavity walls?

For our free government insulation process either glass fibre or mineral wool will be used. Both of these materials allow the building to breathe and are made from water resistant properties meaning no water will be soaked up. Call us on 0800 612 7878.

Our certified installers drill small, refined holes in the cavity wall in a pattern. This allows that each section has been filled at the correct level and all at the same intensity.
