Anglian sash windows are available in traditional wood or contemporary uPVC finishes. uPVC sash windows mimic the look of timber sash windows but have all the modern features that come with uPVC, A-rated energy efficient glazing and extra security.

The Benefits of Anglian Sliding Sash Windows

Quality Build and Design

Available as single or double-hung, which refers to how many sashes on the window can be opened, Anglian sliding sash windows offer a stunning level of detail visible on the outside and an equally impressive build quality hidden inside. Perfectly counterbalanced through a system of hidden runners and springs, the internal open and close mechanism opens and closes with a smooth and easy action.

Our range of beautiful sash window colours preserve the authentic look of a classic sliding sash window. Select from a single colour frame or our dual colour options to create a different look on the outside of your home.

Reinforced Against Intruders

Anglian sash windows are built to keep you and your home warm, safe and secure. Made with toughened glass accredited by the British Standards Institute (BSI) and high energy ratings as standard, our double-glazed sash windows are draught free when sealed tight in winter and let the breeze flow in on hot summer days. There's a range of security features built-in to both our uPVC and timber double glazed sash windows, including a security bar and reinforced sashes to prevent intruders trying to lever open the window. Choose to add lift restrictors to lock the sliding sash window open ajar for ventilation, preventing it from being opened fully

Sash Window FAQs

Can you double glaze existing sash windows?

If you are looking to double glaze existing sash windows and are looking for a more affordable option, then we’d suggest considering secondary double glazing. Secondary double glazing fits over your existing windows, providing extra warmth and sound insulation.

Can you insulate sash windows?

You can insulate sash windows with cost-effective secondary glazing. However, if your windows have seen better days and are draughty, it might be time to consider new double-glazed sash windows to improve your window insultation.

What are timber sash windows made from?

Timber sash windows can be made from softwood or hardwood. Anglian offer a choice of both, sustainably sourced from the Forest Stewardship Council (FSC). The timber is weather-sealed, which means it won’t rot, warp or shrink.

How do you measure up for sash replacement windows?

To measure up for replacement sash windows, you need to measure the sash window width and height, as well as the box frame width and height (the size of the hole in which the window is set). Anglian replacement sash windows are custom made to fit your home, fill in the form on our website and we’ll send a member of the team out to measure up for you

Can you soundproof sash windows?

Yes, secondary glazing will provide your existing sash windows with additional soundproofing. However, windows with a higher energy rating tend to also come with better soundproofing. If you’re not sure which option is right for you, please talk to our team and we’ll be happy to explain the differences and benefits.
