Dempsey Dyer takes Heritage Flush Sash to the next level with full mechanical joints

12 June 2017

heritage flush sash window In late 2016 Yorkshire fabricator, Dempsey Dyer launched the Deceuninck Heritage Flush Sash window available with welded transoms, mullions and frames. The company is now delighted to offer the same window fully mechanically jointed.

The Heritage Flush Sash is a uPVC sash window that balances modern performance with traditional design, boasting A+-rated thermal efficiency and PAS24-compliant security alongside excellent weather performance.

By developing this product with convincing timber-style mechanical joints, Dempsey Dyer demonstrates their industry-renowned expertise in both uPVC and traditional joinery that’s seen them rise to become one of the UK’s most respected fabricators.

“We’re thrilled to be able to offer the Heritage Flush Sash windows fully mechanically jointed,” commented Dempsey Dyer MD, Peter Dyer. “In the past decade, we’ve seen a dramatic rise in the number of end-users looking for windows and doors that deliver both the timeless aesthetics of timber and the exceptional modern performance of uPVC. It’s something we’ve already tapped into with our own Beaumont window – but the mechanically-jointed Heritage Flush Sash offers our trade clients another high-quality timber-alternative option.”

Unveiled at last year’s FIT Show, The Heritage Flush Sash comes available in a choice of 26 colour options from stock including matching cills, trims and ancillaries. Unusually for a flush sash window, it also comes with night vent functionality.

Founded in 1977 by brothers Tom and Bob Dyer, and today run by Tom’s son Peter, Dempsey Dyer is currently celebrating its fortieth year in business and is proud to still be a family owned and run business. The company’s relationship with Deceuninck has grown over 30 years, with the two firms collaborating to produce Dempsey Dyer’s signature Beaumont window range, featuring mechanically-jointed uPVC frames with an authentic woodgrain appearance.
