Internal wall insulation involves applying high-performance thermal boards or stud-wall systems to the interior of your external walls. This process is highly effective for homes where external insulation might not be possible due to planning restrictions or architectural features. By creating a thermal barrier, we stop heat from escaping through your walls and eliminate cold spots where condensation and black mould often thrive. Our installers meticulously manage thermal bridging solutions, ensuring that your home retains heat for longer while reducing your reliance on expensive central heating systems throughout the winter months.

We take quality and safety seriously, operating strictly in accordance with PAS 2035 whole-house retrofit standards. As a SWIGA-backed contractor, we provide insurance-backed guarantees that offer you long-term protection and confidence in our work. Our team handles every stage of the process, ensuring full compliance with current UK building regulations and the Minimum Energy Efficiency Standards (MEES) for landlords. By improving your property's EPC rating, we not only make your home more comfortable but also ensure your investment remains compliant and valuable for years to come.

One of the key advantages of choosing Global Energy Insulation is our seamless end-to-end service. Once our team has professionally installed your thermal insulation, we work alongside our sister company, Global Plastering, to provide a high-quality finish. This means your walls are perfectly prepared, skimmed, and ready for decoration immediately after the installation process. By combining our expertise in energy efficiency with their traditional plastering skills, we eliminate the need for you to coordinate multiple contractors, ensuring a clean, professional, and efficient turnaround for your home improvement project.

Many homeowners ask if IWI will significantly reduce their room size; while there is a slight reduction, the gain in thermal comfort and energy savings is substantial. Others wonder about the installation timeframe, which depends on the size of your property, though our experienced team works efficiently to minimise disruption. We are also frequently asked about damp prevention, and we are proud to confirm that our systems are designed specifically to manage moisture and prevent the growth of black mould common in older solid-wall houses. If you have further questions regarding your specific property type, we are here to provide expert, tailored advice.
