Insulation How To Guides

A three bedroom semi detached house with no insulation costs more than three times as much to heat as an energy-efficient house with full insulation and a modern boiler. It can lose up to 75% of heat through the roof, walls, windows, floors and doors.

Heat can be lost around ill-fitting doors and windows. Insulation will help to retain the heat in winter and also helps to keep the house cool during a very hot summer.
