Authentic Sliding Sash Windows

If you live an older property here in Newbury, our sliding sash windows are perfect for you. While their design can aid the visual appeal of both modern and traditional properties alike, they make for an excellent addition to the latter. Installing them is a superb way of improving your home’s overall performance while maintaining the classical period charm.

Sliding sash windows operate on a vertical slider, opening upwards within the frame. These windows were first introduced alongside Victorian era properties, and thus deliver elegant, traditional aesthetics wherever they are fitted. Our replica vertical sliders are designed as a modern alternative to these classical profiles, which were often made from timber.

With this, our sliding sash windows can prove for an excellent long term investment. You won’t be troubled by poor weatherproofing, thermal retention or home security ever again. Instead, you’ll have a bespoke set of new windows fitted, available in a range of woodgrain foils and with high quality and authentic hardware. We have options for every taste and budget.

Our vertical sliding windows are available with a comprehensive range of featured ancillaries. In doing this, they can always adhere to the latest building regulations in your area. You can commission our services knowing you’ll secure planning permission thanks to the profiles we use. We work with an industry leading supply chain to take the stress away from the installation.

Thermal Performance

Our sliding sash windows can achieve fantastic levels of energy efficiency. Being a uPVC profile, they retain just as much heat as any of our modern casement or tilt and turn profiles would. You’ll enjoy thermal retention that far exceeds what an outdated vertical slider is capable of.

If you’re renovating an older property, this improved thermal performance could make a vastly significant difference to your home. The enhanced energy efficiency could even result in cheaper utility bills over time, as it will be easier to warm your house through.

Full Weatherproofing

Our sliding sash windows are fully weatherproof. Innovative weatherpile sealing fitted around the perimeter works to prevent water ingress. Meanwhile, by using uPVC over timber for the profile, there are never any concerns about permeability years down the line.

In comparison, older wood can often begin to soak up water once it’s reaching end of life. With this, older properties with original vertical sliders are often bothered by damp, rotting or mould. Combat this by installing modern sliding sash windows in your home.

Home Security

One significant benefit of having new window profiles installed is the improved home security. Our sliding sash windows are as secure as any of the other styles we offer. With this, you can have complete peace of mind regarding the safety of your family at night.

A concealed perimeter locking system makes it almost impossible for unwanted intruders to break in through these sliding sash windows. The security is enhanced through central catches, corner sash locking and an aluminium reinforced profile.
