Vertical Sliding Windows

The best-selling Vertical Sliding Sash Window by Epwin Window Systems was one of the first uPVC sliding sash window systems to enter the UK market. Over 20 years later it’s maintained its status as the market leader because it delivers traditional sash window elegance and authenticity at every level. Our vertical sliders are renowned in the industry for their faithful replication of timber sash styling and for their advanced features. They include sashes that tilt inwards for ease of cleaning, child-safety catches, secure locking mechanisms and effective weatherseals.

The system delivers a true authentic appearance that perfectly replicates a timber box sash window. Available in a choice of welded and mechanically jointed frames, and with a new ultra-slim meeting rail option, the attention to detail is evident at every level. At the same time, it delivers impressive performance credentials and meets or exceeds minimum requirements. It’s a combination that means it ticks every box.

Even better, and great news when you’re replacing timber sashes, these widows are designed to achieve a Window Energy Rating (WER) of ‘A+’. If you’re trying to match existing glazing, you’ll love the options available with our vertical slider. These include Georgian bars, sash horns and deep bottom rails as well as a wide choice of colours, cills and hardware.
