Arched and square

Masterframe has launched its London Sash and Frame system, designed to replace timber windows with an arched exterior and square interior, commonly found in Victorian buildings in London and the surrounding areas.

The system shares all the benefits of Masterframe’s Vintage Collection and means that installers don’t have to rely on finding a bespoke design to achieve this window style, the company said.

Ray Rabett, technical director at Masterframe, said: “We were first approached about this window style when a customer was replacing windows at Guildford High School. The existing sash windows were square internally, but arched externally, and there wasn’t a solution on the market for a like-for-like replacement.

“We worked with them to deliver a solution for the project, but soon realised that this wasn’t a oneoff; there were plenty of buildings around the London area that had this window style.”

Masterframe now produces CAD drawings for each individual window specifying the PVCU London Sash and Frame to ensure accuracy. High-quality panelling is then shaped by Masterframe’s team to fit each individual aperture and sprayed to colour-match the sash window. In the Masterframe factory, fabricators piece this panel with the window.

London Sash and Frame is faster to install than traditional arched windows and made bespoke to fit the original architecture, the company said.
