Tradeglaze has strengthened its commitment to building safer homes by achieving Secured by Design accreditation for its range of uPVC windows and doors manufactured at its Lincoln factory.

The achievement is welcome news for local housebuilders, developers and construction companies looking to meet advanced security standards on new build housing developments and refurbishment projects.

Secured by Design (SBD) is the official police security initiative, which works alongside the construction industry to reduce crime through better building design and physical security. Its standards are widely recognised across the housing sector and can help Lincolnshire developers demonstrate that their projects meet recommended security specifications.

Tradeglaze’s newly accredited product range includes its Liniar 70mm uPVC casement windows, Resurgence flush casement windows, tilt and turn windows, uPVC entrance doors and French doors. The certification covers a broad selection of window configurations, providing flexibility for different architectural styles and project requirements.

Tradeglaze customers can now confidently incorporate certified windows and doors into residential developments, refurbishment programmes and other projects where advanced security is a recommendation or requirement.

Head of Production at Tradeglaze, Jonathon Price, said:

“Achieving Secured by Design status is a proud milestone for our entire team following months of dedicated work.

 

“This will be valuable for our customers, who now have access to a wide range of independently certified uPVC windows and doors. These highly secure products ensure compliance on modern projects and play an important role in building safer homes and communities across the East Midlands.”

The process involved independent product testing and certification, alongside production audits and work by Tradeglaze’s team to meet the stringent manufacturing standards. The company has also undertaken training on system upgrades, with support from leading uPVC profile supplier Liniar.
