35% of Our Domestic Heat Is Lost Through Uninsulated cavity walls

What Is A cavity wall?

The gap between the 'leaves' or walls of the building which was originally created to allow any rainwater that penetrates through the outside wall, to drain down the inside of the wall to below the damp proof course (DPC).

InstaFibre for cavity wall insulation

Instafibre is a blown mineral wool which, once installed for the cavity wall insulation, forms an insulative barrier which retains the heat inside your home.

It works by storing the heat in the inner wall and radiating it back into the home with the effect that you can turn down your heating without losing out on comfort. It also maintains a constant temperature throughout the home.

One of the benefits of this is to help eliminate condensation on walls. Draughts are also reduced as InstaFibre seals off the gap around badly fitted doors and window frames.
