The Look of Tradition, The Ease of Today
The Legacy uPVC sliding sash windows carry all the beauty of a traditional design, coupled with all the benefits of modern materials that enable us to offer a cost effective, low maintenance window that doesn’t compromise on aesthetics. From near-invisible joints, the elegance of the run-through sash horn to the curvy ovolo frame shape, these are just a handful of the many clever details that work together to create the most graceful and advanced sash window on the market.

About
Sash Lock and Keep
Our locking system securely fastens the mid-rails of sash windows, ensuring a firm and reliable closure. Available in two distinct styles, the system comes in both standard and heritage finishes to complement various aesthetics.
About
Corner Joints
Standard Mitre Welds
​
Our standard welding technique ensures that the corners are tightly bonded, creating a seamless and strong connection. The 45° corner welds are carefully cleaned using advanced machinery providing a clean frame finish.
​
Timber Looking Mechanical Joints
​
The fully mechanical joints take authenticity to another level because the 45° uPVC welds on the frame and sash are replaced with 90° mechanical joints as found on traditional timber windows.
About
Deep Bottom Rail
​
​Choose a deep bottom rail if you want your box sash windows to look as close to the original timber sash version as possible. The fully mechanical deep bottom rail convincingly mimics the bottom sash of timber windows from the Victorian era and looks great with run-through sash horns.
​
About
Run Through Horns
By removing the lip on the sash horn edge, a new refined sash horn can carry a woodgrain foiled end cap that run seamlessly with the shape of the horn. The sash horn utilises mechanical joints rather than welded to allow the horn to be a continuous part of the sash giving the window a more authentic overall look. The new horn is available with the inclusion of a slim midrail only. On windows with a standard midrail, the run-through horn will look slightly different.
About
Slim Midrail
The styling details of our sash windows are now more rooted in history than ever before. The new 37mm slim midrail will reaffirm the Legacy’s position as one of the most authentic sash windows on the market ideal for period properties or homes in conservation areas. Please note the slim midrail is available with the inclusion of run-through sash horns only and on windows with a minimum width of 436mm. Limitations on colourways may apply, please ask upon enquiry.
Supporting British Industry
Our sliding sash windows are manufactured right here in the UK and adhere to British standards.
