WHAT IS INTERNAL WALL INSULATION?
Internal Wall Insulation (IWI) is a highly effective way to improve your home’s energy efficiency by insulating the inside of external walls. It involves fitting insulation boards or stud walls with insulation material onto the inner surface, then finishing with plasterboard for a clean, modern look. This method is ideal for solid-wall properties or where external insulation isn’t possible, helping to reduce heat loss, lower energy bills, and create warmer, more comfortable living spaces while also tackling issues like condensation and damp.

HOW IS IT FITTED?
Internal Wall Insulation (IWI) is installed by constructing a stud wall against your solid walls, using insulated battens filled with high-performance mineral fibre insulation.
