Choosing the right method for your property depends on its structure and your personal requirements. External Wall Insulation (EWI) involves applying high-quality thermal boards to the outside of your home, followed by a durable, weather-resistant render. This is an excellent solution if you want to improve your property’s thermal performance without sacrificing internal floor space. For properties with historical facades or those in conservation areas where the exterior look must be preserved, Internal Wall Insulation (IWI) is the ideal alternative. Our team conducts a thorough survey to help you decide which approach will best improve your home energy efficiency and overall comfort.

Energy efficiency is no longer just about comfort; it is about compliance and value. Whether you are a landlord in Llanilltud Fawr needing to meet the latest MEES requirements or a homeowner looking to improve your property's EPC rating, our team is here to help. We operate as a PAS 2030 and PAS 2035 accredited contractor, ensuring every stage of your retrofit—from assessment to installation—meets strict government standards. By choosing a professional, accredited firm, you ensure that your investment is protected by SWIGA insurance-backed guarantees, giving you total peace of mind for the long term.

Solid walls are often prone to thermal bridging, where cold spots occur on internal walls, leading to condensation and black mould growth. This is a common issue we tackle across the Vale of Glamorgan. By installing modern insulation, we effectively seal the building envelope, preventing heat from escaping and keeping moisture at bay. This not only makes your home much easier to heat during the winter months but also creates a healthier indoor environment for your family. Many of our clients find that the reduction in energy consumption pays dividends quickly, especially when combined with potential support through the ECO4 grant scheme.

A successful retrofit requires more than just high-quality insulation; it requires a flawless finish. While Global Energy Insulation handles the technical retrofit, our sister company, Global Plastering, provides comprehensive traditional and modern plastering services to ensure the internal or external aesthetic of your home is perfectly restored. By combining these two specialist services, we offer a seamless end-to-end experience for all our customers in Llanilltud Fawr and Llantwit Major. From the initial survey to the final coat of render or plaster, we manage the entire project with the expertise and professionalism you expect from a local leader.
