products that are perfect for the end user today, and tomorrow. And we are still growing our PVC-U range of products. “Following on from the success of our flush sash window system, we have recently completed a huge programme of investment and product development to deliver a flush sash door system too. Both systems have been designed with features to keep PVC-U fabricators and installers ahead of the competition.” Robert describes what makes the new Flush Sash Door System so special: “The new Flush Sash Door System offers the same high level of energy efficiency as our Flush Sash Window System, with a double-glazed door with full steel reinforcement able to achieve a 1.2w/m2K u-value. This is particularly exciting because some of our competitors need to remove the steel from the sash or frame, or even mullion to achieve a similar result. We can achieve these impressive u-values because we utilise a pseudo chamber concept, whereby the steel reinforcement in a 5 chambered profile is shaped to achieve a simulated 6th chamber. “Another technical detail that puts our PVC-U Flush Sash Door System customers ahead of the competition is the co-extruded flipper gasket that seals onto the frame, rather than needing to be rolled in. This gasket is also set back so that it doesn’t protrude the gap between sash and frame. We have also ensured the best possible aesthetics with a sash to frame sightline of 145mm and a frame to sash gap of just 5mm.” The Flush Sash frame can be manufactured with the company’s C70 or O70 systems allowing for chamfered or ovolo detailing on the internal view of the window or door. The system has also been designed with thicker side walls to ensure timberweld and mechanical weld prep detail is more robust, and can achieve glazing depths of 28mm, 36mm and 40mm. Robert concludes: “We hope customers and peers will vote for Kömmerling to win PVC Systems Company of the Year because we are continuing to invest to ensure we keep delivering technically better PVC-U window and door systems that stay ahead of increasingly stringent standards, today and in the future.” Voting closes on the Friday 19th September (5pm) .
