WHAT IS INTERNAL WALL INSULATION?
Internal Wall Insulation (IWI) is an effective solution for improving your home’s energy efficiency by insulating the inside of external walls. The process involves fitting insulated boards or stud walls lined with insulation material, then finishing with plasterboard to create a smooth, modern interior.
​
This method is especially suitable for solid-wall homes or properties where external insulation isn’t an option. It helps reduce heat loss, lower energy bills, and create a warmer, more comfortable living space—while also addressing common issues such as 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.
