The Dualframe 75Si casement window builds upon proven polyamide thermal break technology and is the first aluminium window to achieve a UK "A++" BFRC rating.
The DF 75Si Casement window's excellent performance characteristics make it an ideal solution for today's residential projects.
The specialised profile range adds great flexibility when constructing windows where inward and outward rebates have to be combined without the need and expense of coupling sections or dummy frame to fixed lights.
