What is External Wall Insulation?

Houses built without cavity walls, or properties constructed with a cavity too narrow to be insulated now fail to meet current building regulations. These houses often suffer from damp, mould and condensation on internal walls which not only represents a health risk, but in some cases can even make a property uninhabitable. The value of these properties can fall dramatically as a result of poor or non-existent insulation.
Mullen EWI provides complete home insulation which effectively wraps your home in a thermal blanket, making the property warm, dry and significantly cheaper to run. Insulating boards are permanently fixed to all of the external walls, encasing the building in a secondary skin. A wide variety of render finishes can be installed to give modern, seamless finishes or to replicate traditional construction with specially trained External Wall Insulation installers.
