Ultimate Rose uPVC sash windows

Ultimate Rose sash windows

Our Ultimate Rose uPVC sash window epitomises the Roseview design philosophy – it’s an outstandingly authentic, exceptionally-performing work of art.

Every detail of the Ultimate Rose  replacement upvc sash window has been designed to replicate the charm and character of a timber sash window. With slim timber-like profiles and an industry-leading 35mm meeting rail, no other sash window can compete with 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 spot that it’s uPVC.

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

35mm meeting rail

At 35mm the Ultimate Rose sash window meeting rail is the slimmest on the market. It’s almost 10mm slimmer than our standard Heritage meeting rail, and leads the way in truly authentic 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 exactly like a single solid piece of timber.

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

Mechanical joints

You won’t find any welds on an Ultimate Rose sash window – everything is fully mechanically jointed.

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

Run-through horns

Several years ago we designed our own run-through horn system, rather than leaving it to the systems companies.

Using a simple and bespoke horn design which – crucially – is topped off with a flush fitting cap, the result is the most authentic run-through horn you can get.

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

Slim sightlines

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

It has flat putty-style external glass lines and subtly-moulded internal ones, which are fully 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 our Ultimate Rose uPVC sash windows.

Foiled finishes

Ultimate Rose sash window comes in white ash woodgrain finish as standard, but you can also choose from plain white, cream woodgrain, golden oak and rosewood.

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

Whatever colour your customer needs, we can sort it out for you.

Modern features

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

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

Like 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 uPVC sash windows are very low maintenance and never need repainting.
