Improving your home energy efficiency usually involves either External Wall Insulation (EWI) or Internal Wall Insulation (IWI). EWI involves fixing an insulating layer to the outside of your property, which is then finished with a high-quality render. This is an excellent way to refresh your home exterior while dramatically reducing thermal bridging. Alternatively, IWI is applied to the inner surface of your external walls, making it ideal for buildings where maintaining the original exterior aesthetic is essential. Our team assesses your property structure to recommend the most effective approach for your specific build.

We go beyond simple installation by adhering to strict PAS 2035 standards. As fully accredited PAS 2030 specialists, we provide end-to-end retrofit coordination and assessment. This ensures that your insulation project is compliant with modern building regulations and effectively addresses moisture management. For landlords across Monmouthshire, our services are vital for improving your property EPC rating to meet current MEES requirements, ensuring your investment remains compliant and attractive to tenants.

A successful insulation project relies on expert finishing. Through our close partnership with our sister company, Global Plastering, we provide a complete, seamless service. Whether you require meticulous internal plastering after an IWI installation or expert external rendering—including silicone, monocouche, or K Rend systems—we ensure the final result is as durable as it is aesthetically pleasing. You benefit from a single point of contact for the entire thermal upgrade of your home.
