Deltalock - Winlock Launches First For Flush Sash Windows

• New Deltalock offers a night vent position without compromising the window’s weather seal.

• Provides enhanced security with 3 corner locking points.

• Presents the most visually appealing product on the market.

Window hardware pioneer; Winlock Security, has designed the first locking system that enables Flush Sash windows to be held in the “night vent” position without compromising the external gasket, security or design.

Flush sash casements are one of the fastest-growing areas in the UK window market with several system companies taking advantage of this trend producing new profiles in the last 2 years and with more in the pipeline. Yet one significant drawback of several of these systems has been the window’s inability to ‘hold’ in a ventilation position. Unless a fabricator was prepared to sacrifice the external gasket, Flush Sash windows are either fully locked or completely unsecured, that is…. until now.

Winlock has designed the Deltalock, an innovative shootbolt locking system with a double cam arrangement held on the delta-shaped plate close to the window’s corner to enable the windows to be fully locked or secured in the “night vent” position. In the fully closed position, it also provides exceptional security with 2 cams and a shootbolt all within 100mm of the corner. The clever design also ensures aesthetics aren’t compromised, as all hardware components remain behind the gasket - where they should be.

This exciting patented product, launching under the new Deltalock™ brand, has already been independently tested to PAS024 on both Eurocell Modus and Veka flush sash casements, with additional profiles in the pipeline.

Commenting on the launch Winlock Security MD Alan Parker said: “Many customers were frustrated by being unable to offer night vents on expensive flush sash casements unless they compromised the external seal. We decided to design something unique, specifically for flush sash systems so that our customers can offer the same high levels of security and range of features which are taken for granted on other window systems.”

Deltalock will be available from August and reflects Winlock’s innovative solution ethos.
