HWL Windows is claiming a first with the launch of its Kömmerling flush sash exclusively with the patented Timberweld finish.

“Aesthetically, it delivers all the attention to detail you would expect from a premium German brand and that is enhanced further with our capacity to offer it with a Timberweld 90-degree joint,” said director Graham Howatson.

“It looks outstanding, but it also performs very well. It’s built around a new, 6-chambered profile which help it to achieve U values of 1.2 (W/m2K),” he continued. “That’s good news for our customers as it means they can offer a desirable, high value product without having to worry if it complies to the new Part L regulations.”

The new Kömmerling flush sash is available from HWL with 21 foiling options from stock, in addition to a ‘fast track’ service on other finishes, and with glazing options from 28-40mm.
