Traditional buildings were designed to breathe, meaning modern, impermeable insulation can often cause trapped moisture, leading to severe damp and decay. Our approach focuses on breathable internal wall insulation and advanced wood fibre systems. These materials manage moisture levels naturally, preventing condensation and black mould while eliminating thermal bridging. By upgrading your historic home in Caerdydd / Cardiff, you protect the structural integrity of your building and create a more comfortable, draft-free living environment.

Upgrading a listed property involves complex regulatory hurdles, from planning permission to strict conservation area guidelines. As a PAS 2035 compliant specialist, we manage the entire retrofit process, ensuring that all work meets the necessary building regulations without compromising your property's heritage status. We act as your expert partners in navigating these requirements, providing the necessary documentation and technical expertise to keep your project compliant and stress-free.

We offer a truly complete service by collaborating closely with our sister company, Global Plastering. While our insulation team focuses on the technical thermal upgrades, our plastering experts specialise in traditional lime plaster finishes that perfectly complement the original aesthetics of your home. This integrated approach ensures that your property is not only warmer and more efficient but also beautifully finished to the highest standard, matching its historic character.
