Within homes the walls and loft are the main source of heating loss. Insulation provides an extra barrier, preventing the warm air from escaping as much. As a result having cavity wall insulation and loft insulation can dramatically reduce household energy bills. It will also improve a property's EPC (Energy Performance Certificate) rating, which can in turn increase the property value and ensure the home meets basic energy efficiency standards.
There are many reasons why the insulation in cavity walls may be removed. In some cases, it may be installed incorrectly or a property may not have been suitable in the first place. It is also possible for damage to cause problems with the insulation, such as damage occurring to the external brickwork.
