The Victorian Sliders® Cutting-Edge Manufacturing Process

Our South Wales factory is home to seven high-tech extrusion lines. Using the latest technology and high-tech machinery, we produce precision engineered PVC-U windows for UK trade customers. Once the window profiles are extruded, they are cut to size and drilled using automated Shirmer machines that ensure the most accurate measurements are achieved. From here, the windows’ corners are welded into position using nine Urban welders with run-through sash horns incorporated into the window frame where required.

Advanced glazing and window fabrication

The Victorian Sliders® factory is equipped with its own on-site glass shop. From here, we produce our own IGU A-rated double-glazed units. Every glass pane is cut to size on site and passed through a toughening process to maximise strength and durability. We also have the capacity to add Argon gas to the sealed unit as standard to enhance the thermal performance of each window unit.

Once the window unit is glazed and sealed, it must pass through quality control and final assembly. Our team of glazing experts have extensive experience within the window manufacturing industry. At this stage, they are responsible for assembling the windows, inserting wool pile, attaching all hardware, and completing a final quality control examination. Reflecting our commitment to excellence throughout the entire process. 

Extrusion Lines

Victorian Sliders extrudes PVC-U profile exclusively for ECOSlide sash windows. We do this on-site at our HQ in Wales, with 7 extrusion lines.

Cutting & Drilling

One of many important stages is the cutting to size and drilling of the window, for this we use automated Shirmer machines which work to precise measurements to ensure every job is accurate.

Welding & Prep

The automated process continues from welding the window’s corners into position with 9 Urban welders, through to the prepping stage where the window is manufactured with run-through horns when required.

Glazing

Our on-site glass shop enables us to produce our own IGU A-rated double glazed units, each piece of glass is cut and toughened in the factory. 

Fabrication

Our skilled workforce are trained in precision and attention to detail when assembling windows, from inserting wool pile through to fixing hardware and thorough quality control, every stage is looked after by at least one dedicated team member.

Delivery & Depots

We own our own fleet of HGV transport vehicles, which distribute windows from our manufacturing facilities in South Wales to 6 regional depots. Our regional depots allow us to deliver windows efficiently to trade customers throughout the UK using Sprinter vans.
