Benefits Of uPVC Window Sash Replacement

Energy Efficient

It’s a good idea to replace sash windows with new modern uPVC sash windows just for the incredible energy efficiency contemporary windows provide. With bespoke double glazing, our window sash replacements can help retain natural heat within a home, leading to less heat escaping and being wasted. The glazing accomplishes this by trapping heat between the two panes, preventing it from escaping through the glass. Homeowners could even save on their energy bills by not needing to rely as often on their central heating systems to keep themselves warm and comfortable. As a by-product of using less energy, customers could also reduce their carbon footprint!

Want to replace sash windows in a traditional home but don’t want to miss out on that heritage aesthetic? Fret not—with Quickslide, we can provide a wide range of authenticity features, including slim midrails, 90-degree joints, woodgrain foils, run-through horns, and more!


Old sash windows will likely need to be replaced because they are made with less refined materials. Window sash replacement today can be done with a variety of new materials like plastic, steel, and aluminium. uPVC is an excellent modern material to replace sash windows with due to it having a high amount of strength while also having the ability to be coloured in a vast range of hues and shades. Replace sash windows with our uPVC models, and you’ll benefit from highly durable frames that can withstand all kinds of weather with tight weather seals that could prevent draughts and leaks.

uPVC sash windows can last for decades without having their colours or foils fade, so by installing our windows, homeowners could benefit from gorgeous designs without needing another window sash replacement for years to come.

Low Maintenance

Most older sash windows are made from timber, which can not only warp but usually needs to be sanded, repainted, varnished, or repaired quite often. Install window sash replacements made with new uPVC alternatives, and customers can enjoy reduced upkeep with much lower maintenance costs. There’s no need to repaint, sand, or varnish uPVC sash windows, and thanks to the robust profile, they can resist warping much better than traditional timber. Additionally, the hidden chambers inside the profile make the uPVC profile fantastic at retaining heat alongside the double glazing.

Slimmer Sightlines

If you replace sash windows with a new installation, it could also give homeowners the opportunity to flood their homes with natural light, as newer uPVC manufacturing technologies and techniques can lead to slimmer yet sturdier frames that provide larger panes of glass without compromising security or structural integrity. Any home could benefit from more natural light throughout the day, leading to less reliance on indoor lighting.
