External Wall Insulation

Many older homes don't have a cavity between outer and inner walls. This makes insulating the walls much more important as solid walls will lose more heat than walls with a cavity.

The only way to reduce this heat loss is to apply insulation to either the inside or outside of the wall. Not only does this help to reduce heat loss but it also helps to prevent condensation on the walls and can also reduce heat build up during the hotter months. Additionally you will soon see a reduction in your heating bill and this helps to play a part in reducing your overall CO2 emissions.

How external wall insulation works

This involves adding a decorative weather-proof insulating treatment to the outside of your wall. The insulation is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work providing the opportunity of adding insulation.

The savings

External wall insulation is more expensive than cavity wall insulation but it could save you around £300 a year on your energy bills.

A three bedroom semi-detached house could save nearly 2.5 tonnes of CO2 a year. More information on the make up of the Exterior Wallcoat textured coating can be found here
