What is IWI?
Internal wall insulation (IWI) is a highly efficient energy saving measure that involves fitting insulation material to the interior walls of your property. This is then covered in a vapour barrier to protect from air and moisture penetration.
Any wall sockets will be extended so that they are still functioning, any removed radiators will be refitted, and the walls are completely re-plastered ready for redecorating post installation.
What are the benefits?
Internal Wall Insulation prevents heat loss, keeps individual rooms warmer all whilst saving you up to 35% on your energy bills. IWI also significantly reduces the possibility of condensation appearing in your home.
What does it cost?
The cost of installing IWI varies depending on the number of rooms, and their dimensions, to be insulated. Kitchens and bathrooms are excluded from works due to the walls not being unobstructed. All the installers we work with offer a 25 year warranty on any IWI installed.
You may be eligible for ECO4 or Government lead funding schemes to contribute to or cover the cost of IWI installation on your home.
