Insulating the inside of your exterior walls can be a cost-effective way of cutting down your heating bills – and also a more aesthetically pleasing option than external wall insulation.
You also have a wider choice of options:
- Best thermal value – high performance but relatively expensive
- Standard – good performance and more affordable
- New technology wall coverings – good performance and much thinner
How it works
- Best thermal value – high performance insulated plasterboard, usually containing high density foam, is fitted to the inside walls of your home
- Standard – ordinary expanded foam backed plasterboard, usually around 40mm thick, are fitted to your inside walls
- New technology – ultra-thin rolls of insulating material (usually around 10mm thick) are added to your inside walls in a similar way to wallpaper
How it's installed
- Best thermal value – high performance plasterboard is fitted onto 25mm thick wooden battens
- Standard – good performance plasterboard is fitted onto 25mm thick wooden battens
- New technology – 10mm thick flexible wall coverings are stuck onto your inside walls with a special adhesive, then rendered, painted or wallpapered
