Ultimate Rose is our most authentic uPVC sash window. Its ultra-slim 35mm midrail, seamless construction and true mechanical joints provide an unmistakably classic solid timber look and feel. The deep bottom rail, putty line detailing and choice of textured finishes complete the look externally, while its optional staff bead does the same on the inside. In short, it’s the best timber-alternative sash window on the market. Period.
“Quite simply, the UK’s most authentic timber-alternative sash window.”
Ultimate Rose is the epitome of the Rose Collection design philosophy – outstanding aesthetics and exceptional performance. Ultimate Rose is, quite simply, the UK’s most authentic timber-alternative sash window.
It redefines tradition.
We’ve re-engineered the timber-alternative sash window from the ground up, looking at every seam and detail that differed from a timber original and designing it out. The ultra-slim 35mm meeting rail, the seamless run-through sash horns and even the internal sash interlock – everything has been redesigned to achieve what no other timber-alternative sash window can; a smooth, seamless finish. The result is that even from close up only an expert can tell that it’s not timber.
But while Ultimate Rose may look identical to traditional timber sash windows, the one place it’s designed to be different is in performance.
‘A’-rated energy efficiency, high security and independently tested sound insulation mean that not only will your home look great with Ultimate Rose, it will be warm, quiet and secure.
Add all this together and you get a modern sash window that looks and performs better than anything else on the market. That’s why we call it Ultimate Rose.
From the outside, the Ultimate Rose sash windows are completely indistinguishable compared with authentic timber. In fact, the difference is so hard to tell, even up close, that our Ultimate Rose sash windows have been accepted in hundreds of sensitive conservation areas where maintaining traditional aesthetics is crucial.

Most uPVC windows are easily identifiable, not only from the outer sash, sill and beads, but also from more subtle details like the interlocks, capping profiles, inserts, horn caps and astragal bars.
We’ve spent almost two years working on removing these seams and PVC lines from our market-leading sash windows. Ultimate Rose was already the most authentic uPVC sash window on the market; with the latest iteration, redesigned from the ground up, we’ve pushed standards even further.
Seamless run through and no-horn options, no front-facing cap lines or wraparounds, minimal astragal bars all give the exterior a remarkably clean aesthetic. On the inside face we changed the interlock and added a flush-fitting removable staff bead, covering the sash lines for a traditional period look. You can now even opt for a matt finish as opposed to woodgrain for an even more authentic look.
Ultimate Rose has been designed from the ground up to use end-capped true mechanical butt joints on the frames and sashes, just like those on a timber window.
Typically, a standard uPVC window would have 45 degree grooves or fake mechanical joints where the profiles have been welded together. With subpar double glazed sash windows, this will be a clear indicator that it is made from uPVC as opposed to timber.
With the Ultimate Rose we use a unique, innovative manufacturing process that allows us to eliminate the tell-tale corner weld altogether, using a traditional joinery method instead. This means you get traditional vertical and horizontal butt joints, exactly the same as a timber window. We even go to the trouble of making sure the orientation is right – horizontal joints on the frame and vertical on the sashes – as this is what they’re like in timber. The result is strength and authenticity on frame and sash that replicates timber construction. Because some things just can’t be faked.
Victorian and Edwardian sash windows – and those that followed – typically had sash horns. Before that, particularly in the Georgian period, sash horns were much less common. That’s why Ultimate Rose is available either with or without seamless run-through horns – to match the style and history of your home.
