Heritage Windows


This window system is designed as an extremely slim-line thermally efficient Heritage window. When combined with our patented Ste’alth Secure™ Locking, it makes for an incredibly strong and secure window. This window uses the latest ‘Polyamide’ thermal barrier technology, has authentic furniture options and butt hinges or mock butt hinges and is still a fraction of the cost of steel windows. Our Heritage Windows are suitable for new build as well as replacement or refurbishment projects and can (and has been) approved for use in Grade II listed buildings and conservation areas.
