Seamless corners and ETL joints

Quickslide has introduced seamless corner joints to its casement window range, and external timber look (ETL) joints as a new option on its flush sash range of windows.

Available on both classic casements and flush casements, seamless joints are created using a Graf seamless welder, which eliminates the welding seam seen on standard 45° mitre-jointed PVCU windows.

Unlike these standard window joints, where the window is welded together creating a molten plastic sprue that is cleaned off to leave a slight groove, Graf-welded windows reverse the process so the sprue is pushed back into the frame, resulting in not only a stronger weld but also creating a seamless join and high-quality finish.

The finished seamless corner is perfect for Quickslide’s textured wood-effect windows that look just like traditional timber, the company said. Quickslide, in partnership with Deceuninck, offers 22 woodgrain colourways from stock as well as the option of bespoke wood-effect windows.

ETL joints externally use the appearance of 90° butt corner joins to replicate traditional joiner-made timber windows, while underneath is still a 45º cut. This design is crafted using a series of dedicated machines with various milling processes to turn out a strongly welded joint internally and a mechanical joint externally. Coupled with realistic wood grain effects and the flush frame finish, these windows offer a modern alternative to timber windows, the company said.

Ben Weber, Quickslide’s managing director, said: “Since Quickslide first entered the market over 15 years ago, our focus has been on replicating the period look with all the benefits of PVCU.”
