‘Incredible’ results in destructive
testing for new system
» SHEERLINE CLASSIC, THE NEW
residential aluminium window system from
Garnalex has passed the PAS24:2016 security
test with flying colours, defeating two test rigs
on the way.
PAS24:2016 testing requires each loading
and locking point of a window to withstand
a perpendicular applied load of 3kN (a kN or
kilonewton is the equivalent of 300kg) and
a parallel to plane load of 1kN. A maximum
sized double side hung Sheerline window
successfully passed both mechanical and
manipulation tests with no issues at all.
Having passed the tests successfully,
Garnalex 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 also achieved extraordinary
results, withstanding 5kN of force before the
lock failed. This was all the more impressive as
the window had already been subjected to full
mechanical and manipulation tests.
In previous testing carried out at Archibald
Kenrick & Sons test facility, Steve Williams,
Kenrick’s Sales and Marketing Director was
equally as impressed.
Phil Parry, Sheerline Testing and Standards
Director, adds: “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.
“Both window hinge and lock sides
withstood loads in excess of the much more
onerous PAS24:2016 door test where the
perpendicular loads are 4.5kN, and even went
beyond that required in EN1627-30.
“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.”
