Sash Window Restoration, Replacement Sashes

The English Riviera was the destination for this sliding sash window project. The scope of works being to upgrade the traditional box sash windows for improved thermal efficiency. With a requirement for minimal disturbance, our customer was looking for an alternative solution to complete window replacements.

This property benefited from high quality existing box frames, requiring minimal repairs. We were able to install replacement double glazed sashes (the sliding parts) into the existing box frames along with our sash window draught seal system, enhancing noise reduction and energy efficiency.

Arched top sashes are always a little more challenging to manufacture however, with accurate templating and CAD design software we were able to match the existing profiles exactly. The replacement sashes were manufactured from Accoya for maximum service life and minimal maintenance. Being fully painted and glazed in our local workshop meant the installation process was more time and cost efficient than replacing the entire windows.


The double-glazed sashes incorporated our unique perimeter draught seal system for maximum heat retention whilst eliminating rattles and reducing external noise pollution. Replacement lockable hardware completed the windows for maximum security.

“We wanted to replace our old, draughty, single-paned windows with something more energy efficient whilst maintaining the character and integrity of the building. JTP Joinery offered great advice on how best to achieve this.
Their staff were always punctual, respectful and took great pains to tidy up after themselves. They worked to exacting standards and the finished result is fantastic!”
