Internal Wall Insulation in Rhisga / Risca , Caerphilly

Living in a home with solid walls often means cold surfaces, draughts, and high monthly energy bills. Our professional team addresses these issues by installing high-performance insulation boards directly to the internal face of your external walls. This process drastically reduces thermal bridging, which is a common cause of cold spots and damp build-up. By creating a thermal barrier, we significantly improve your property's EPC rating and overall thermal comfort, ensuring your living space stays cosy throughout the winter months.

As a PAS 2030 accredited business, we follow a rigorous, professional approach to every retrofit project. We begin with a detailed survey to assess your property's specific wall structure and moisture levels. Our skilled team then carefully installs premium thermal liners or rigid PIR boards, followed by a high-quality plaster finish. This ensures that your walls are not only thermally efficient but also perfectly prepared for painting or wallpapering. We handle every detail, from site protection to the final skim, leaving your room looking pristine and feeling much warmer.

We operate within a 35-mile radius of our base, providing specialist insulation and plastering services to domestic and commercial clients across Caerphilly and South Wales. Whether you own a terraced house in the Valleys, a flat in a multi-occupancy building, or a commercial office space, our team is equipped to handle the complexities of older and non-traditional builds. We pride ourselves on delivering consistent, high-quality results that meet current energy standards while maintaining the character of your property.
