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.
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.
