Essex based U70 is the latest fabricator to introduce Kömmerling’s flush sash window, which can achieve a U-value of 1.2W/(m2K) with a standard double glazed unit.
There are 20 different colour combinations from stock including smooth grey both sides on a grey base and a further 58 available on a short lead time. The sash profile has a six-chamber design with a 7th pseudo chamber. It also incorporates additional material for welding technologies including Mechweld that’s been adopted by U70 as an upgrade option from the standard welded corners.
U7 Director Martin Killick: “The Kömmerling flush sash is the best 70mm product in the market by some way. The performance, looks and ease of manufacturing make it a must have product for us and our local installer partners, and we encourage anyone in our area to have a look at this new window.”
