How does it work?
Internal wall insulation (IWI) involves applying insulation material to the interior surface of walls, usually covered with plasterboard or a similar finish. This method improves thermal efficiency and reduces heat loss within the home.
IWI can significantly decrease energy consumption, resulting in up to 25% reduction in heat loss through walls. Additionally, it helps to minimise draughts and effectively tackles condensation and damp issues, promoting a more comfortable indoor environment.
