Cavity wall insulation
Between 25 %– 40% of heat is lost through an uninsulated cavity wall. By insulating, you could be reducing your heating costs by 15% and save around 800kg of carbon per annum.
“Cavity wall insulation is a great and easy way to significantly reduce the amount of energy you need to heat your home. The average house could reduce heating costs by 15%*. In fact, between 2002 and 2005 around 800,000 households installed cavity wall insulation. It is estimated that these households will collectively be saving nearly 400,000 tonnes of carbon dioxide a year, enough to fill the new Wembley Stadium 46 times...every year! “

Installing Rockwool EnergySaver blown insulation into a cavityIn most houses built after the 1920s, the external walls are made in two layers with a small air gap or 'cavity' between them. This gap can vary in size, but if you were to insulate it, you would be able to save significantly on the energy you use to heat your home.
Rockwool EnergySaver cavity wall insulation is an entirely dry system which uses granulated Rockwool blown into an external wall cavity to a predetermined density. No glues or catalysts are involved in the installation procedure.
