Internal wall insulation

Internal wall insulation could lower your energy bills by £930 each year.

Installed in homes with solid walls, internal wall insulation cuts heating costs and makes your home more comfortable.

How internal wall insulation works

Wall survey
A survey is performed to determine the condition of the walls and the required logistics for an installation.
Walls prepared
Any issues with penetrating or rising damp are resolved prior to installation.
Rigid insulation boards are installed to the internal walls, or stud walls are built filled with insulation material such as mineral wool fibre.
Warmer home
Insulation creates a barrier to stop warm air from leaving through your solid walls.
