Victorian Sliders

Europe’s Largest PVC-U Vertical Slider Manufacturer

Victorian Sliders are Europe’s largest specialist manufacturer of PVC-U vertical sliding sash windows, extruding and fabricating made to measure ECOSlide windows in a purpose-built 240,000 square foot production facility based in Carmarthenshire, South Wales.

Every aspect of product design and fabrication is carried out by our team under strict quality control procedures, from the specification of specially formulated raw materials, to the extrusion of highly engineered PVC-U window profiles, woodgrain foil or colour spray surface finishing of the window frame components, toughened sealed double glass unit production and final assembly of complete sash windows.



Using our own fleet of transport vehicles, we distribute finished windows to regional depots in readiness for local delivery to Professional Trade Installers, who in turn supply and fit ECOSlide windows for their retail customers.

Victorian Sliders only supply ECOSlide sash windows directly to Professional Trade Installers and therefore do not sell to the general public. An extensive network of Professional Trade Installers regularly buy ECOSlide windows and these retailing companies provide surveying, quotation, sash window supply and installation services on behalf of UK homeowners.
