Internal wall insulation involves applying high-performance insulating materials to the inner face of your external walls. This process acts as a thermal blanket, significantly reducing heat loss and eliminating the cold spots often caused by thermal bridging. By retaining warmth, you can reduce your energy bills and create a much more stable, comfortable living environment throughout the year. As PAS 2030 accredited specialists, we ensure that every installation meets rigorous safety and performance standards.

Many homes in Penarth, particularly Victorian terraces and older traditional builds, suffer from poor energy efficiency due to single-skin solid walls. IWI is an ideal solution for these properties where external wall insulation may not be feasible due to planning restrictions or architectural features. Beyond thermal benefits, our insulation helps prevent damp and condensation issues by keeping the wall surface temperature higher, which is essential for maintaining a healthy indoor climate. Improving your EPC rating is also a major advantage, helping landlords meet current MEES compliance requirements with ease.

We pride ourselves on offering a seamless experience from start to finish. Our team handles the entire PAS 2035 retrofit process, including professional assessments and coordination. Because we work alongside our sister company, Global Plastering, we provide a comprehensive service that includes all necessary plastering and finishing work. This means your walls are left professionally finished and ready for decoration immediately after the insulation is installed. Our work is supported by SWIGA insurance-backed guarantees, ensuring you have total peace of mind in the quality and longevity of your home improvements.
