As part of its commitment to offer customers the best products possible, Sheerline Aluminium Systems has achieved PAS24: 2016 on its Prestige window system. Prestige is the second Sheerline product to gain Secured by Design accreditation, the UK’s official police initiative that works with companies to improve security on buildings.

Prestige builds on the success of Sheerline’s Classic range, a slim, beadless system that also passed the BSi BS 4873:2016 / PAS24:2016 security performance test in 2021. The test evaluates the strength of a window at each locking point, as well as its overall performance when under attack.

Product Design Director, Adrian Redshaw stated, “PAS24: 2016 for window units is set at a specific standard to ensure the complete product resists attack. It focuses on withstanding manipulation of the window hardware and combines mechanical loading, leverage and pressure, and impact testing. The Prestige window came through the tests without a hitch, exceeding many of the required classifications needed to gain a pass certificate and allowing us to attain endorsement by the Secured by Design initiative.”

The Prestige window evaluated, used Sheerline’s unique corner cleat a precision and incredibly easy to fit, standardised component from the Sheerline range of products. Designed to eliminate misalignment, the corner cleat adds strength to the overall frame and sash. To bolster the windows security further, Yale’s high-security twin cam locking mechanism and 17mm stack height friction hinges were also fitted.

“We expected remarkable results from the Prestige window system, and we weren’t disappointed. We built the system to the same set of principles as our Classic window range; to be innovative, easy to manufacture, simple to install using standard components, while delivering sleek and uninterrupted sightlines that perform to the highest-levels of security.” Adrian commented, “Adding, Prestige to our Secured by Design product listing is a massive accomplishment for us, one which should also gain competitive benefits for our customers.”
