The Ultimate Rose uPVC sash window embodies the Roseview design philosophy – it’s a notably authentic, exceptional-performing work of art.

Each detail of the Ultimate Rose has been designed to reflect the charm and character of a timber sash window. With slim timber-like profiles and an industry-leading 35mm meeting rail, there is no other sash window can challenge it on style and authenticity. And with period features as painstakingly detailed as joinery-style mechanical joints, a deep bottom rail, run-through horns and external putty lines, it would take an expert to identify it as uPVC.

Add to that the number of benefits that come with state of the art materials and techniques – from energy efficiency and security, through to sound insulation and low maintenance – and you’ll see why Ultimate Rose epitomizes the pinnacle of uPVC sash window design. It’s also the reason it won New Product of the Year in the prestigious G13 Glass and Glazing Industry Awards.

Slim meeting rail

At 35mm, our meeting rail is the slimmest on the market.

Mechanical joints

No welds, just traditional butt joints, just like timber.

Run-thru horns

Single-piece sash horns with bespoke flush end caps.

Slim sightlines

The slimmest sightlines of any uPVC sash window

35mm meeting rail

At 35mm the Ultimate Rose meeting rail is the thinnest on the market. It’s almost 10mm slimmer than the standard Heritage meeting rail, and leads the way in truly original uPVC sash window design.

And by designing our own meeting rail we’ve also done away with the tell-tale external interlock line. Now the meeting rail looks precisely like a single solid piece of timber.

It’s just one more detail that gives Ultimate Rose its authentic appearance and sets it apart from the competition.

Mechanical joints

You will notfind any welds on an Ultimate Rose – everything is completely mechanically jointed.

Using the custom-designed jigs, blocks and brackets, every join on the frame and sashes is finished as a butt joint – exactly like a timber window. What’s more, the frame is joined horizontally while the sashes are merged vertically. Not only does this add strength and rigidity, it exactly mimics the way original timber sashes were joined.

It’s this attention-to-detail that makes Ultimate Rose the most authentic, conservation-friendly uPVC sash window on the market today.

Run-through horns

Several years ago Roseview designed their own run-through horn system, as opposed to leaving it to the systems companies.

Employing an uncomplicated and bespoke horn design which – essentially – is topped off with a flush fitting cap, the end result is the most authentic run-through horn you can obtain.

They could have gone down the easy route and designed a bold horn with a “hide all sins” wraparound horn cap. But at Roseview they were not interested in just finding the easiest path; they’re about making the best, most authentic windows they can.

Slim sightlines

The Rehau Heritage VS profile is the envy of the industry, as it has the slimmest sightlines available.

It has flat putty-style external glass lines and subtly-moulded internal ones, which are competely matched on the astragal bars. It also has triple-sealed concealed brushpiles, silver or white gaskets (so that they don’t stand out like black does) and an authentic deep bottom rail.

In short, the Rehau profile is simply the best one on which to base Roseview’s Ultimate Rose windows.

Foiled finishes

Ultimate Rose is offered in white ash woodgrain finish as standard, but you can also opt for plain white, cream woodgrain, golden oak and rosewood.

On top of that, we can factory-spray the windows in any RAL colour you decide on, either all-over or external only.

Whatever colour you need, we can sort it out for you.

Modern features

Ultimate Rose has been especially designed to be the most credible uPVC sash window you can get. But, that’s not done at the cost of modern features and benefits.

These comprise of ‘A’ rated energy efficiency as standard, enhanced security and superb acoustic performance helping to block out external noise.

As with every window in the Rose Collection, both sashes tilt inwards to make them easy to clean from the inside. And best of all, Ultimate Rose windows are extremely low maintenance and never need repainting.
