Innovative, Smooth and Functional

We’ve designed our Legacy™ Sash windows with a clever balance mechanism for an easy, smooth operation. No old box sash, no cords and no weights for a simpler smoother glide. Both sashes adjust separately or can be opened together and both feature an innovative tilt mechanism, allowing the glass to be tilted inwards for ventilation or cleaning. Our uPVC sliding sash windows open smoothly, with ease using a smart balance mechanism so you’ve no need to worry about snagging cords or jammed pulleys. They also meet the fire safety ‘means of escape’ requirements in case of emergency.

Superior security

When you buy your windows from us, you can rest assured they’ll come with a wide range of security features. All our windows are precision made, so we’ll install flush sash uPVC windows with an air-tight seal. They’re also internally beaded, which stops the glass from being removed from the outside, and include anti-jemmy bars as standard to prevent the sash being levered open. The central lever frame lock secures both sashes together with a key lock for added protection, and you can include opening restrictors as an optional extra to limit the height the sash can be opened. We’re BM Q-Mark certified, reassuring you that our sash windows exceed the stringent security requirements for certification.

Excellent energy efficiency

Our uPVC double glazed sash windows are recommended by the Energy Saving Trust. They allow free heat energy in from solar grain, potentially lowering your energy bills and keeping the elements at bay with triple brush pile weather seals. The argon filled glazing and high performance low-E glass reduces heat loss through the glass, while the multi-chamber frame with thermal inserts reduces heat lost through the frame.

Sash Windows FAQs

How do sash windows work?

A sash window design consists of a single or multiple movable panels, known as sashes, which have a vertical sliding mechanism. Glazing bars separate these sashes, with counterweights connected by spiral balance springs or sash cords which allow them to stay open.  

The main distinction between sash and casement windows are that sash windows open vertically, whereas casement windows open outwards. Sash windows are also more traditional and complex in design, while casement windows are more contemporary and low-maintenance.

Can sash windows be double glazed?

All our uPVC sash windows come with double glazing as standard. Our uPVC double glazed sash windows are an ideal option for those who live in conservation areas and wish to complement the aesthetics of classic or period properties, while enjoying the benefits of improved energy efficiency and enhanced security.

How much do sash windows cost?

The cost of sash windows depends on various factors, including your home, design choice, finishing options and the time taken to complete your installation. We do not have standard pricing and recommend you discuss your requirements with a specially qualified advisor for an accurate quote. You can be sure you are getting the best uPVC sash windows cost though, thanks to our Price Promise, which means we’ll beat any genuine like for like quotes.
