Internal Wall Insulation in Trecceln / Newbridge , Caerphilly

Many properties in the Valleys were built with solid walls that lack the thermal performance of modern construction. Internal wall insulation is the ideal solution when external rendering or cladding is not an option, perhaps due to planning restrictions in conservation areas or the need to preserve the original facade of a period property. By installing high-performance insulation boards to the interior of your external walls, we significantly reduce thermal bridging and prevent the cold damp feeling that often affects older terraces. This process creates a thermal barrier that retains heat, drastically lowering your energy bills and improving your property's overall EPC rating.

As a PAS 2030 accredited company, we follow strict industry guidelines for every project we undertake. Our process begins with a detailed retrofit assessment to ensure the insulation system is perfectly suited to your building type, whether it is a residential flat, a semi-detached house, or a commercial office. We install high-quality insulation boards followed by a professional plastering finish, ensuring your walls look as good as they perform. Because we are experts in plastering, you can rest assured that your internal walls will be finished to a smooth, ready-to-decorate standard.
