Classic charm and modern convenience

Want the authentic appearance of timber sash windows but don’t want the hassle of regular wood treatment and window maintenance? Win-Dor uPVC sash windows are the perfect solution, combining both the traditional aesthetics of a timber box sash window with the low maintenance levels and general convenience of modern uPVC materials.

Ultimate levels of authenticity

uPVC sash windows from Win-Dor feature traditional design details to ensure that they are virtually indistinguishable from classic timber frames. Our windows can not only boast slim sightlines, Georgian bars, and a deep bottom rail, but also the option to feature clip on or run through horns, so you can choose if you want to exactly replicate traditional timber aesthetics.

Our uPVC sash windows are the perfect choice if you live in a conservation area, or are just interested in maintaining a particular aesthetic. Our heritage vertical sliders – manufactured in-house – have even been designed in consultation with several housing and conservation associations, so you can be assured that they meet the required standards of authenticity for areas sensitive to aesthetic change.

High performance sash windows

Whilst our sash windows have a strong emphasis on authentic appearance, they also offer excellent levels of performance in terms of security and thermal and acoustic insulation. We can manufacture sash windows with a triple chamfered profile design, meaning that they can achieve an ‘A’ Window Energy Rating (WER) even without installing additional thermal inserts. For excellent levels of security, our windows can be supplied with anti-jemmy security bars to prevent easy intrusion, whilst triple brush seals help for superior draught proofing.

Low maintenance levels

Win-Dor vertical sliders are also designed to be low maintenance as well as aesthetically pleasing. They are perfectly balanced meaning they won’t stick, jar or slip, and cleaning them couldn’t be easier – they incorporate a built in tilt feature which means that you can clean both sides of the window from the inside of the house.
