Internal Wall Insulation

Solid wall insulation types

Rigid insulation boards

Rigid insulation boards are around 2½ to 4 inches thick, and made of plasterboard backed with insulation material, usually foamed plastic. They’re normally fixed to the wall with ribbons of plastic or adhesive, or fitted to battens if the walls are lumpy and uneven.
The installer will add extra fixings to hold the boards firm, and seal the joints between the boards.

Stud walls

Stud walls are made of metal or wooden frames, which are attached to the solid wall. Once the insulation material has been inserted into the gap between the studwork frame and the wall, the new wall is plastered. It can then be painted or wallpapered, to look however you like!
Alternatively, it could be covered with rigid insulation boards, making your insulation even more effective and your running costs lower. But remember, this could also have an impact on the size of your room.

• It’s usually less expensive than external insulation
• It’s easier to install, and there’s no need for scaffolding
• It won’t change the outer appearance or character of your home, so it’s more suitable for visually attractive buildings and period properties
• It’s also more suitable for flats and maisonettes – as you can hardly use external insulation for just one unit in a block!
• It can also be acceptable for buildings in conservation areas, where there are often strict rules about the kind of changes you can make to the outside appearance of your home
