Internal wall insulation involves applying high-performance thermal materials to the inside surfaces of your external walls. This creates a powerful barrier that prevents heat from escaping through solid masonry, effectively solving the issue of cold walls that radiate a chill into your living rooms and bedrooms. By treating these surfaces, we significantly reduce thermal bridging, which is a common cause of condensation and black mould growth in older Swansea homes. The result is a home that stays warmer for longer, requires less energy to heat, and enjoys a much healthier indoor climate throughout the year.

We follow strict PAS 2035 retrofit standards to ensure every installation is tailored to the specific needs of your building. Our process begins with a detailed assessment to identify the most suitable insulation materials for your wall type, ensuring no compromise to the building's breathability. Once the insulation boards are securely installed, we coordinate seamlessly with our sister company, Global Plastering. This allows us to provide a comprehensive end-to-end service, where our expert plasterers apply a high-quality finish to your walls, leaving your home ready for redecoration immediately after the work is completed.

Many homeowners ask if IWI will significantly reduce their room size, and while it does add a small layer to the walls, the gain in thermal comfort far outweighs the minimal space loss. Others enquire about the installation timeframe, which depends on the size of the property, but our team works efficiently to minimise disruption to your daily life.
