Weatherglaze Windows has made a major investment in three Graf Synergy seamless welding machines from Haffner.

The investment includes the new Graf Synergy Seamless SL8-FF TR CNC 8-Head Welding Machine and two Graf Synergy SL4-FF EVO Seamless Welder, which is said to enable Weatherglaze to further enhance the quality, efficiency and aesthetic appeal of its premium window and door offering, manufactured using aluplast’s PVC-U systems.

The investment is said to mark two significant industry milestones.

Weatherglaze becomes the first company in the UK and Ireland to take delivery of the new Graf Synergy SL8-FF TR CNC 8-head welder, and the first fabricator in Ireland to install Graf Synergy seamless welding technology.

Based in Gorey, County Wexford, Weatherglaze has been manufacturing PVC-U windows and doors for more than 45 years.

The company has reportedly built its reputation on continually investing in advanced fabrication technology to deliver premium products and exceptional service to its trade customers.

Manufacturing aluplast’s IDEAL 70, flush sash neo plus HST85 Lift and slide, neo smart-slide and aero-slide patio systems, Weatherglaze is well placed to take full advantage of Graf Synergy’s seamless welding technology.

The technology is said to be particularly suited to aluplast’s premium finish foils of woodec and aludec, designed to replicate the appearance of timber and aluminium respectively, these premium finishes rely on corner detailing to maintain their authentic appearance.

Jim Dempsey, Chairman at Weatherglaze, said: “We continually look for ways to improve both the quality of our products and the efficiency of our fabrication, so investing in Graf Synergy’s seamless welding technology was an easy decision.

“The quality of the finished welds is superb. Unlike traditional fabrication methods, where welded corners need to be penned to disguise the weld seam, Graf Synergy technology produces a perfectly seamless corner straight from the machine.

“Not only does this save significant fabrication time, it also delivers a superior finish that will look just as good years after installation because there is no penning to fade.

“Combined with the premium appearance of the aluplast systems and decorative foils, it enables us to offer an even higher quality product to our customers.”

Chris Curran, Area Sales Manager at Haffner, commented: “We’re delighted Weatherglaze has invested in Graf Synergy technology from Haffner.

“By embracing the latest generation of seamless welding technology, they’re strengthening an already impressive fabrication operation and giving their customers access to the highest standards of PVC-U window quality and aesthetics.”

Continuing its programme of investment, Weatherglaze has also become the first fabricator in Ireland to introduce aluplas’s energeto neo system to its product range.

Combining this next-generation PVC-U system with Graf Synergy’s seamless welding technology is said to create a class-leading, high-performance window solution, giving Weatherglaze a unique and compelling offering in the Irish market.
