External Wall Insulation at Competitive Prices
Insulating your solid walls will cut your heating costs considerably, because solid walls let through twice as much heat as cavity walls do. The good news is they can be insulated.
If your home was built before 1919, its external walls are probably solid rather than cavity walls. Cavity walls are made of two layers with a small gap or ‘cavity’ between them. Solid walls have no gap, so they let more heat through.
Another way to tell is by measuring the width of the wall. Look at an external wall window or door and if the brick wall is less than 260mm, then it is likely a solid wall, while if it is greater, it is probably a cavity wall. Find out about insulating your cavity wall. If you live in a house that is not made from bricks, such as a steel or timber-framed building, insulating will be different.
