Internal Wall Insulation

For solid-walled homes without cavity walls, keep heat in your home with an insulated layer added to the interior faces of your outside-facing walls.

What is internal wall insulation?

If your home was built before the 1920s, it’s likely to have solid walls without a cavity, which of course makes it unsuitable for cavity wall insulation. Fortunately, we can apply a layer of insulation to solid walls on the inside of your property. This is a significant home improvement project with its own set of challenges.

How does internal wall insulation work?

Internal wall insulation typically involves creating a new stud wall over the surface of your existing walls, finished with plasterboard to leave a smooth and clean surface for redecoration. Insulation material can then be applied between the two wall layers. This is a challenging job which often requires moving any fixtures attached to the affected walls, such as radiators, switches or kitchen units – however, creating an airtight insulated seal between your walls offers huge benefits in heat retention.

If the prospect of redecorating and potentially remodelling the inside of your home doesn’t appeal to you, you might want to consider external wall insulation instead.
