Internal wall insulation is the ideal solution for properties where external wall insulation is not possible, such as homes in conservation areas or period buildings where the original exterior aesthetic must be preserved. By applying high-quality thermal boards to the inside of your external walls, we stop heat from escaping through the structure of your home. This process addresses cold wall treatment effectively, reduces damp and condensation issues, and provides a significant boost to your EPC rating. Whether you live in a Victorian terrace or a modern apartment, IWI is a proven method to reduce your carbon footprint and slash your monthly heating costs.

Our approach is rooted in technical expertise and compliance. As PAS 2030 accredited specialists, we follow strict PAS 2035 whole-house retrofit standards to ensure that every installation is safe and effective. The process begins with a professional assessment to determine the moisture risk and thermal requirements of your home. Our team handles the installation of insulating boards and vapour barriers with precision, preventing issues like thermal bridging. Once the thermal upgrade is complete, our sister company, Global Plastering, provides a professional, seamless finish, ensuring your walls are ready for immediate decoration.
