Installing Cavity Wall insulation – the benefits
Installing Cavity Wall insulation can make a big difference to your home’s comfort and energy efficiency. It can effectively prevent your home from losing as much as a third1 of its heat through the walls. So you can stay warmer and benefit from welcome savings on your energy bills.
It’s estimated that installing Cavity Wall insulation can save you up to £145 every year on heating bills.
Quick and easy installation with minimum disruption
Cavity Wall insulation is designed to fill the gap or cavity between the two layers of brick that make up the external walls of a property. If you’re not sure if your home was built with cavity walls, a big clue is it was probably built some time after 1920.
