Legacy PVCu Sliding Sash Windows

Our new Legacy PVCu sliding sash windows hold a host of impressive features that not only add to its good looks but also enhance the performance of the product as well as ease of fabrication and installation.

Vertical Sliding Sash Windows Explained

Designed to replicate the traditional timber sash window whilst incorporating the benefits of PVC-u making this a virtually no maintenance solution. Our PVC-u Sash Window operates like a traditional box sash window, both the top and bottom sashes slide up and down, and tilt inwards as standard.

We use the very best hardware, including top-of-the-range machinery, which makes our hand-built sash windows a true replica of the heritage sash windows they could be replacing.

Vertical Sliding Window Options

Our sash windows come in a carefully selected range of stock colours. Create a natural feel with some of our realistic wood effect sash windows, or create a beautiful contrast with a subtle black. Grey sash windows are also very popular and suit new builds perfectly. White sash windows are the most ubiquitous and are available in both a smooth and wood effect finish. We also offer heritage green tones including Chartwell and Agate grey as ready-made options. Lighter and darker shades are available and we’re always happy to help you find the perfect window colour to suit your home!
