Sheerline has announced that the entire Prestige range now carries Secured by Design (SBD) accreditation, along with double-glazed Part L compliance. 

Prestige builds on the success of Sheerline’s Classic range of ultra slim aluminium windows 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, said: “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 range 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.

“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 and simple to install using standard components, while delivering sleek and uninterrupted sightlines that perform to the highest-levels of security.”
