Unglazed R9 accreditations
A non-glass bonded Residence 9 window from HWL Trade Frames has passed independent PAS24 testing to achieve Part Q approval.
Coming less than a month after achieving a series of top-rated passes under BS EN 6375-1 weather testing, Graham Howatson, director at HWL, said that PAS24 approval makes the case for buying in R9 on a frame-only basis compelling.
“We have had a great response from installers to frame-only R9 supply because it offers them installation efficiencies and they can buy-in IGUs from their usual supplier,” he said. “Handling is easier, it saves you time, it saves you money and we can now underpin our offer with not only a 10-year guarantee but also a series of top accreditations.”
The specialist trade fabricator has led the development of an R9 frame-only offer, pioneering the application of Timberweld sash-welding technologies in its manufacture. This gives HWL the capability to butt-weld window sashes inside and out, replicating the aesthetic delivered in a 90° mechanical joint. This process increases sash corner strength, which in most configurations eliminates the requirement to glass bond IGUs.
Conducted in partnership with the Residence Collection, the HWL window was put through its paces under PAS24 at the beginning of May by independent testing house, Exova. This returned a series of clear passes under PAS24 test requirements for mechanical load and manual intervention testing.
