The firm is now able to supply products that meet BS644 for enhanced security timber windows and doors, BS7412 for enhanced security uPVC windows and doors, and BS 8529 for enhanced security composite doors.

Dempsey Dyer continues to comply with ISO 901:2008, which covers the manufacture of uPVC windows, doors and conservatories, and is registered with the British Fenestration Rating Council.

“We’ve taken this decision to streamline our processes and make life simpler for our customers,” commented Mark Suaznabar, Dempsey Dyer compliance and quality manager.

“We want to offer our customers the greatest possible assurance, and allow them to meet the demands of any property or project.”

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 and is proud to still be a family owned and run business.

In the decades since, the Yorkshire-based fabricator has grown to become one of the region’s foremost providers of timber and Deceuninck uPVC. In recent years, the company has combined the two specialisms to produce the Beaumont window range, mechanically-jointed uPVC frames with an authentic woodgrain appearance.
