Millions of properties built prior to 1920 were constructed with solid brick walls allowing twice as much heat to escape compared to cavity wall properties.
Solid wall properties were constructed when the cost of fuel was relatively cheap, allowing burning fires to warm the house throughout the day. As the cost of fuel has increased this in no longer a sustainable option.
External Wall Insulation (EWI) is an ideal solution to thermally improve the performance of these properties, with estimated savings of £490 p/a on heating costs and 1.9 tonnes of carbon dioxide p/a.
Externally insulating these properties dries out and heats up the solid wall, and acts in the same way as a tea cosy would creating a warm dry insulated coating to the property. EWI not only improves the thermal performance but the new insulated facade improves the weatherproofing and appearance of the property.
