Perfect uPVC Sash Windows

In 1985 Roseview were the first company to specialise in timber-alternative sash. Working in partnership with Rehau and a large London housing group, Roseview were involved in developing and manufacturing the UK’s first mainstream uPVC sash window system. Since then we’ve been continue to innovate and develop our windows, always focusing on authenticity, performance and quality. The result is the Rose Collection.

We make one thing and one thing only – sash windows. We talk about them, design them, build them, take photos of them. We’re enthusiastic about them. And all that time and enthusiasm goes into making the very best uPVC sash windows you can buy.

So while other companies may offer sash windows as part of a wider portfolio, we concentrate on making our windows the best that they can be. We think that’s the right way to go.

The Advent of uPVC

Luckily for architects and specifiers, uPVC represented a significant breakthrough in window construction. It offered a naturally insulating material that was also incredibly hard wearing. It could last for years without degrading and offered a completely weatherproof window performance. There was only one problem. They couldn’t replicate the look of sash windows, and therefore lacked the aesthetic qualities associated with them. For years, they weren’t suitable for architects and specifiers who wanted to use sliding sash windows.

Roseview’s Breakthrough

That’s where Roseview comes in. In 1985 we started developing the first uPVC sash windows in the UK, focusing on creating accurate and authentic timber sash window replication. With several innovative design breakthroughs, we pushed the boundaries of what was possible with uPVC materials in a sash framework. Our developments of run through horns and slimmer midrails were unprecedented at the time but have since been copied as a mark of true authenticity. Fast forward to the present day, and we have perfected uPVC sash windows for architects and specifiers.
