Since the mid 1920’s most homes have been built with what is known as a cavity wall, this separates the internal walls from the external walls by having a gap between them, in the order of 2″ to 3″.
According to research, approximately 35% of all heat loss in the home is caused by heat escaping through the wall. To eliminate the heat loss, the gap between the walls can be filled with insulation by injecting them with material that provides a heat proof insulating barrier.
Energy Saving Cavity Wall insulation is estimated save an average household more than £100 a year on combined energy bills also reducing Carbon Dioxide emissions.
Help with the cost of insulating your home can be provided through, grants on offer by the Government and Utility companies.
Solid walls can lose sometimes twice as much heat than insulated cavity walls, but by using modern insulation systems, this can be drastically reduced. Solid wall insulation can be installed either to the outside or to the inside of your home, each one having its own particular benefits.
Internal solid wall insulation can be lower in cost than external solid wall insulation, but it will slightly reduce the floor area of the room.
External solid wall insulation can be done without disturbing the occupants and will refresh and improve the appearance of your home.
