How external wall insulation works

Insulation material
A layer of insulation material is fixed to the external walls of your home.
The insulation is covered with a render or cladding and can be smooth, textured, painted, or finished with brick slips.
Warmer in winter
Insulation creates a barrier to stop warm air from leaving through your walls.
House protection
Reduces condensation on internal walls and improves weatherproofing and sound resistance.
