Heritage Rose Sash Window

Tradition is the watchword of Heritage Rose. Second only to Ultimate Rose in terms of timber authenticity, Heritage Rose is a classically styled sash window that delivers the convenience and all-round excellence of modern uPVC.

Heritage Rose uses the same slim, putty-line profiles as Ultimate Rose, but includes a wider midrail and welded joints. It also features optional flat run-through horns, a deep bottom rail as standard and traditional chamfered astragal bars. And while Ultimate Rose is indistinguishable from timber even from close up, the period detailing and profiles on Heritage Rose mean that from the pavement no-one will know that it isn’t an original timber window.

Heritage Rose has been used in conservation areas across the UK, including the Royal Borough of Kensington and Chelsea, Cambridge, Lincoln, Snowdonia and the Lake District. Like every window in the Rose Collection it offers truly modern performance, keeping your home warm, quiet and secure.

Welded Joints

Heritage Rose features strong welded joints that contribute to their overall structure and rigidity. They are welded at high temperatures which harden the frame further.

Slim 44mm Midrail

At just 44mm, our Heritage Rose sash windows have a slim midrail. That’s amongst some of the slimmest midrail possible through uPVC windows.

Deep Bottom Rail

Traditionally speaking, the bottom rail was made of thick timber. This feature is replicated on Heritage Rose sash windows for true authenticity, in the form of an 81 mm deep bottom rail, resembling traditional timber sash windows’ depths.


We have a variety of foiled finishes available with Heritage Rose sash windows, providing a unique finishing touch. Each finish is fade resistant, ensuring a complete lack of maintenance. Several woodgrain finishes are also available, as well as RAL colours, offering you flexibility to personalise your window.

Please note, actual product colours may vary from the colours displayed on your monitor or device. Please check a RAL colour chart before selecting a particular colour.
