Sash / Vertical Slide Windows

If you’re looking for high-quality sash windows in Cardiff and the surrounding area, then look no further than South Wales UPVC. We make perfect made-to-measure UPVC sash windows for your property, adding character and elegance whatever its age and style.

Our sash windows offer a superior standard of functionality and efficiency, which means that the draughts, shakes, stiffness and difficulty with cleaning that occurs with traditional sash windows are eliminated. Available in a variety of different UPVC shades, our sash windows offer a combination of traditional styling, with high-end, 21st century performance.

Here are some of the fantastic features included with our UPVC sash windows:

Thermally efficient double glazing which incorporates Low E glass will ensure that precious heat won't escape to the outside.
Pre-tensioned spiral balances and sash lifts ease the opening and closing of the sashes, whilst the limit stops restrict the sash opening to 100mm; a useful safety feature if you have children.
Tilt restrictors enable you to tilt the sash windows open enough to clean the outside safely and efficiently.
Double pile weatherstrips are fitted around each sash and across the meeting rails to keep out draughts.
Upon request, we can also include many additional features to add a more authentic look to your sash windows, such as decorative horns, a deep bottom rail, internal and external Georgian inserts, and decorative glazing.
