Continuing Sheerline’s commitment to offering all its products with consistently excellent thermal and security performance, we are pleased to announce that the whole Prestige range now carries Secured by Design (SBD) accreditation.

With the addition of bi-folds and single and French doors included in our scope of approved products, alongside Prestige casement and tilt & turn windows. This means that the complete range of Sheerline aluminium windows and doors now carry SBD approval, alongside double-glazed Part L compliance, giving installers and fabricators the confidence to promote the entire range in a simple and easy to communicate manner.

Secured by Design accreditation, the UK’s official police initiative that works with companies to improve security on buildings, remains an important and crucially, widely known way of informing consumers they are choosing the right products to help keep their homes secure.

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 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 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.” Adrian commented, “Adding the whole Prestige range to our Secured by Design product listing is a massive accomplishment for us, one which should also give our customers a competitive benefit.”
