Established 1977

Roseview has been manufacturing windows since 1977 and switched to specialising in uPVC sash windows in 1985. Nobody else has that level of dedicated manufacturing experience and expertise. It’s a big part of why we continuously push the boundaries of what’s possible with timber-alternative windows, seamlessly combining traditional design with exceptional modern performance.

Roseview Sash Windows

Modern Scale

Given that we’re a niche manufacturer specialising in one product type, customers are often surprised at the sheer scale of our operation. We manufacture hundreds of sash windows every week from our modern 50,000-square-foot manufacturing facility in Olney. Through our unique mix of state-of-the-art technology, more than 100 knowledgeable and experienced staff, and a fleet of ten vehicles, we manufacture and deliver sash windows to hundreds of customers across the UK.

Foiled Sash Windows - Roseview Windows

In-house Foiling

Not many people know we own a specialist foiling company, allowing us to offer a broad range of foiled sash windows at competitive prices with short lead times. This includes our renowned traditional “chalk” textured heritage foil, which closely matches the appearance and feel of painted timber.

Be Spoke Machines - Roseview Windows

State-of-the-art Manufacturing

We’ve invested almost £2 million in leading-edge technology to support our manufacturing operation. We run two bespoke machining centres simultaneously, along with three dedicated CNCs designed specifically for sash windows—the first of their kind in the UK. We also run a bespoke full-service IT operation that tracks windows from initial cut to final QC, then onto our vehicles and all the way to our customers’ doors, providing automated updates to customers along the way.

Innovation - Roseview Windows

Innovation

From the very beginning, we’ve built an unrivalled reputation for innovation. This includes developments such as seamless technology, removable staff beads, flat and seamless run-through horns and traditional deep cells. Recent developments that are unique to Roseview include our innovative chamber filler, Eclipse vent hood, Seahorse pattern run-through horns and – most recently – patented ThermoVFlex technology that provides a 1.2W/㎡K  U-value without requiring specialist triple or vacuum glazing.
