Don’t have a wall cavity? External wall insulation is the best alternative! For solid walls, there are ideally two ways to insulate them.
Internal wall insulation: Internal wall insulation is applied to the inner surface of the main exterior of walls. Typically, this is more cost-effective, but of course, it has some limitations.
External wall insulation: External wall insulation is the process of adding insulation to an already-existing wall. For weather protection, the wall is usually completed with render or another type of cladding.
External wall insulation works wonders to improve the thermal efficiency of dwellings with solid walls.

Lack of a Wall Cavity
Many older homes don’t have a wall cavity, which makes it harder to insulate. If you don’t have a cavity, you can’t use traditional ways like cavity wall insulation. Heating City Energy Ltd offers expert solutions like external wall insulation, designed specifically for houses without cavities.
Don't Lose Floor Space
To insulate internally, you have to put things on the inside of the outside walls, which takes up floor space. Building a wood frame, putting in rigid foam insulation, adding a vapour barrier, and ending with a plasterboard are all parts of this process. As time passes, the Build-up could cause you to lose 100–150 mm of floor space, which is a big problem, especially in homes with smaller rooms.
