Roundbrand are pleased to announce that the new Aluminium Bi-fold Doors are available.
At the heart of the Roundbrand Aluminium Bi-fold Door is a thermal core which significantly outperforms the polyamide thermal breaks commonly used to reduce the threat of cold bridging on aluminium windows and doors. The result is an innovative ‘warm aluminium’ frame construction, carefully dimensioned to provide an optimised 70mm front-to-back overall sash depth, while ensuring market-leading thermal performance thanks to the multi-chambered insulating core.
