Secure night vent setting for flush sash
19th July 2016

WINLOCK SECURITY has designed what it claims to be the first locking system that enables flush sash windows to be held in the night vent position without having to cut the external gasket.

The company says 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 cut the external gasket.

Winlock has designed the Deltalock, 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 has two cams and a shootbolt all within 100mm of the corner. The design also ensures aesthetics aren’t compromised, as all hardware components remain behind the gasket.

This patented product, already been independently tested to PAS024 on both Eurocell Modus and Veka flush sash casements, with additional profiles said to be in the pipeline.

Winlock Security MD Alan Parker said: “Many customers were frustrated by being unable to offer night vent 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.”
