Sash windows are made up of two glazed panels called ‘sashes’ and are either single or double-hung. Moving up and down on a vertical slider, single-hung sashes have only one moving panel, while double-hung means both sashes move. Our sash windows can be tilted open, allowing for easy maintenance and more ventilation.

Reasons to Choose Sash Windows

  1. Warmer Home, Lower Bills

    Sash windows help keep the heat in your home with thermal inserts to stop warm air escaping, and high-performance pile weather seals to reduce draughts.

  2. Perfect for Conservation Areas

    Customisable features like Georgian bars, decorative horns and heritage-style window furniture mean our sash windows are easily tailored for homes in conservation areas.

  3. Open with Ease

    Perfectly counterbalanced through a system of hidden runners and springs, the internal open and close mechanism makes operation smooth and easy.

  4. Modern Security Features

    Key operated cam locks and limit stops are standard on our sliding sash windows. Security bars and reinforced sashes further prevent intruders.

  5. Add Value to Your Home

    Modern double glazed sash windows increase the energy performance of your home and its looks, making them a good long-term investment.

Your Questions on Sash Windows Answered by Us

Can you double glaze existing sash windows?

It is not possible to double glaze existing single glazed sash windows. You can upgrade your existing single glazed sliding sash windows to Anglian double glazed sash windows. If you are looking to increase your window energy performance and are looking for a more affordable way to do so, then secondary glazing is a good option. Secondary glazing fits behind your existing sash windows, providing extra warmth and sound insulation.

Can you insulate sash windows?

The best way to insulate sash windows is 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 A-rated uPVC sash windows to improve your window energy performance.

What are timber sash windows made from?

Timber sash windows can be made from softwood or hardwood. We have a choice of both hardwood and softwood available, made from FSC®-certified and other controlled material. The FSC® label means that wood used for timber sash windows have been responsibly sourced. The timber is weather-sealed and has a 30-year guarantee against rot and fungal attack.

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). Our sliding sash windows are custom made to fir your home, contact us to book a free remote quotation today.

Can you soundproof sash windows?

Yes, the best way to soundproof sash windows is with secondary glazing. However, brand new windows with a higher energy rating tend to also be a significant upgrade from single glazed sliding sash windows for reducing noise. 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.
