New Ultimate Rose launched

We officially launched the latest version of our top-of-the-range Ultimate Rose sash window earlier this year at the FIT Show. Since then, it’s caused quite a stir!

In 2013 the original Ultimate Rose won the prestigious G13 Award for new product of the year. We had made the most authentic, timber-like uPVC sash window on the market, and many thought it represented the pinnacle of what could be achieved with uPVC. They were probably right.

Using Rehau vertical slider profile (already the slimmest VS profile there is), the original Ultimate Rose featured external putty lines, woodgrain finishes as standard, our own flush-capped run-through horn system and timber-like mechanical joints. The result was a window almost indistinguishable from original timber sashes, certainly from a couple of feet or more away (as one customer told us, “It looks more like timber than timber does!”). At the time there wasn’t much more we could do to enhance its authenticity. But that didn’t stop us trying. And after more than two years of research, development and testing, we cracked it!

The new Ultimate Rose features everything the old one did, but with some key enhancements. First and foremost, we developed our own super slim meeting rail profile to replace the standard Rehau version. Although the standard version was already very slim at 44.5mm, having an ultra-slim meeting rail is a key feature of vintage timber sash windows. Our new version – which we designed and developed in-house and have specially extruded just for us – is only 35mm deep – the slimmest available on the market, More importantly, it’s in proportion with the rest of the window, just like on a timber window. After all, there’s no point putting a super-slim meeting rail on a window where all the other profiles are too chunky.

As a result of developing our own meeting rail, we’ve also been able to design out a feature that normally gives away a uPVC sash window – the interlock line. On a standard window this line runs underneath the meeting rail, where the profile cap and main sash profile. On our version the meeting rail profile has the interlock built in, allowing us to have a completely smooth profile underside. As a result – no interlock.

To finish things off we’ve also commissioned a range of bespoke traditional globe furniture, available only on the new Ultimate Rose. It’s available in a new range of vintage colours, and adds the final detail that makes Ultimate Rose indistinguishable from timber.


The response to the updated Ultimate Rose window at the FIT Show was incredible. At times we had a queue of people lining up to see it, and we lost count of the number of comments we had from people who couldn’t believe the window was uPVC, even close up.
