Approved manufacturing methodologies for R9 will be updated by the Residence Collection to reflect the successful completion of testing on HWL Trade Frames’ pioneering non-glass bonded window.
HWL is reported to have ‘driven innovation in R9 manufacture’ through the application of Timberweld manufacturing technologies. This has given the R9 fabricator an almost unique capability in the UK to butt weld R9 window sashes inside and out, replicating the aesthetic delivered in a traditional 90° mechanical joint.
Now – and with independent testing by R9 complete – the system house has confirmed that it is revising its manufacturing manual to include Timberweld sash-welding technologies as pioneered by HWL.
Mark Haley, managing director, HWL Trade Frames, said: “We started supplying R9 unglazed 18-months ago, so it’s been a relatively long road but worth it because of the commercial advantage that it’s allowed us to deliver to our customers.
“Manufacture of R9 using Timberweld means that we can deliver increased weld strength and that eliminates the requirement to glass bond the sash, in the vast majority of installations.
“The benefits are immediate. As an installer you can buy your glass from whoever you normally buy your glass from, if a unit needs replacing, you replace it in the same way as you would a standard unit. But most fundamentally, you take weight out of the installation, making it simpler quicker and reducing cost.”
