Internal wall insulation is a highly effective solution for properties where external wall insulation is not a viable option, such as homes in conservation areas or those with unique architectural features. By adding a thermal layer to the inside of your external walls, we effectively tackle thermal bridging, which is a major contributor to heat loss. This process not only keeps your property warmer for longer but also significantly reduces the risk of black mould and condensation by ensuring your walls remain at a consistent temperature. It is a practical, non-intrusive way to modernise older buildings, including Victorian terraces and solid-wall houses, without changing their external character.

We take a rigorous, whole-house approach to energy efficiency. As a PAS 2035 accredited contractor, we ensure that every installation we carry out meets the highest UK building standards. Our process begins with a comprehensive retrofit assessment to identify the exact needs of your property. We then design a tailored solution that balances thermal performance with breathability, ensuring your home stays healthy and efficient. Our team manages every step of the project, from the initial survey to the final installation, guaranteeing that you receive a professional service that complies with all current regulatory requirements for safety and quality.

One of the key benefits of working with Global Energy Insulation is our commitment to a seamless end-to-end service. We understand that insulation is only half the battle; the final aesthetic of your home matters just as much. Because we work hand-in-hand with our sister company, Global Plastering, we ensure that once the insulation boards are installed, the finish is perfect. Our skilled plasterers specialise in preparing surfaces for decoration, meaning you do not need to hunt for additional tradespeople. From boarding to the final skim, we handle it all with the same high level of craftsmanship that our clients across South Wales expect.

Many of our clients ask if internal wall insulation will significantly reduce the size of their rooms. While there is a slight reduction, we use high-performance, thin-profile materials wherever possible to maximise your space while achieving excellent thermal results. Another frequent question concerns the installation process; it is relatively quick and can usually be completed room by room, causing minimal disruption to your daily life. Finally, we are often asked about damp; because our systems are installed by experts who understand wall breathability, we effectively manage moisture, helping to solve existing damp issues rather than masking them. As a SWIGA-backed contractor, all our work is supported by insurance-backed guarantees for your complete peace of mind.
