Internal wall insulation is often the best solution for older properties or buildings where external wall insulation is restricted by planning or conservation requirements. Many homes in Aberdare suffer from damp and condensation because the walls are cold to the touch. Our IWI systems act as a thermal barrier, raising the temperature of your internal wall surfaces to prevent moisture buildup and mould growth. Whether you live in a Victorian terrace, a stone-built cottage, or an end-of-terrace property, our solutions improve your home's thermal performance while protecting the historic look of your exterior.

At Global Energy Insulation, we pride ourselves on a professional, end-to-end service. As PAS 2030 accredited contractors, we follow rigorous PAS 2035 standards to ensure your home is treated as a complete system, not just a series of walls. Once the technical insulation is installed, we lean on the expertise of our sister company, Global Plastering. This partnership means you get a complete installation and high-quality internal plastering finish in one package. You do not need to worry about sourcing additional trades to finish your walls, as we manage the entire process from start to finish.

For landlords in Aberdare and across Rhondda Cynon Taf, meeting Minimum Energy Efficiency Standards is a legal necessity. Improving your property's EPC rating is essential for continued compliance, especially for HMOs and rental properties. Our team provides professional retrofit coordination and advice, ensuring your insulation project is documented correctly. By choosing our SWIGA-backed, PAS 2030 compliant service, you are investing in a verified energy upgrade that can help your property qualify for potential funding, such as the ECO4 scheme.

Many residents in Aberdare often ask if internal wall insulation will significantly reduce their floor space. While there is a slight loss of room size, our modern, thin-profile materials minimise this impact while providing excellent thermal resistance. Another common concern is thermal bridging; our installers are trained to identify and eliminate these weak points to ensure total coverage. We are fully insured and hold a Waste Carriers Licence, giving you complete peace of mind while we work in your home. Call us today on 01443 809770 to schedule your professional retrofit assessment.
