Security test passed
Sheerline Classicfrom Garnalex has passed the PAS24:2016 security test with flying colours, defeating two test rigs on the way, the company reported.
PAS24:2016 is designed to test the strength of windows and doors and their resistance to opportunistic break-in attempts. Testing requires each loading and locking point of a window to withstand a perpendicular applied load of 3kN and a parallel to plane load of 1kN. A maximum sized double side-hung Sheerline window passed both mechanical and manipulation tests.
Garnalexthen asked BSI’s technicians to carry out destructive testing to see just how strong the window system was. The results were described as ‘incredible’. Sheerline’s hinge side withstood the full loading capability of BSI’s hydraulic mechanical test rig of just over 10kN (over a metric tonne), holding the load for a minute without failure. The lock side of the window withstood 5kN of force before the lock failed – this was after the window had already been subjected to full mechanical and manipulation tests.
Steve Williams, Kenrick’s sales and marketing director, said: “Having witnessed the new Sheerline window easily passing the required 3kN standard, Garnalex asked us to test their new window to destruction to see what it could take. However, we had to stop the test at 10kN as we were concerned we would damage our test rig. Really impressive performance, and testimony to what the correct system and hardware combinations can achieve.”
Phil Parry, Sheerline’stesting and standards director, said: “These results prove Sheerline’s Classic aluminium windows will set the new benchmark for strength and security for mainstream residential windows. Sheerline exceeded the required loads for PAS24:2016 by more than three times, to the amazement of the technical staff carrying out the testing.”
He continued: “We’ve designed Sheerline from the ground up to make it easy to fabricate, install and sell, and to perform at a much higher level than fabricators and installers are used to. So, we’re pleased, but not surprised by these security test results.”
