Most houses built in the UK before 1930 were constructed with solid brick walls, making them unsuitable for standard cavity wall insulation, there are also properties built after then that may have solid walls.
Also some properties despite maybe having a wall cavity find that it is unsuitable for Cavity Wall Insulation. The solution - use an External Wall Insulation System!
External Wall Insulation can allow these properties to be insulated without causing any problems to the construction.
Here are some great installation photos, we are sure you will agree the finished results are superb!
