Independent research of the PVC-U flush sash market reports nearly half of the fabricators interviewed see flush sashes becoming as important as standard casement windows in the next 10 years. And a quarter of those who don’t make flush sashes now said they expected to start in the next twelve months. The research was undertaken for Timberweld® by MRA Research.

Timberweld is a patented method of welding perfect corners to create an authentic timber-look butt-joint effect. Uniquely, Timberweld allows fabricators to create the timber-look on both sides of the window.

Earlier this year Timberweld commissioned MRA Research to conduct independent research into the flush sash and timber alternative market with fabricators. Of the fabricators interviewed, all those who make flush sashes weld them; 90.7% of these weld conventionally, with 45-degree corner grooves. Some of the fabricators who weld flush sashes also use mechanical joints – with 85% of joints (by volume) being welded and 15% mechanically jointed.

“Most of the fabricators who were interviewed loved the look of the flush sash, in particular the timber-look butt joints,” comments Alan Burgess, Managing Director of Timberweld. “They saw demand growing fast, but a significant number thought mechanically jointing was ‘a pain to fabricate’ and want to weld to meet volume demand cost effectively. And ‘aesthetically’, hidden welding was rated the best.”

Alan adds: “The research echoes what we’ve found in the market – fabricators are looking to create a timber look butt-joint cost-effectively at scale, in order to take advantage of the opportunities the flush sash market offers.
