How do sash windows work?

Right across Cheltenham, sash windows are a charming memento of an elegant era gone by. As the ‘cultural capital of the Cotswolds,’ there are plenty of late Georgian architectural examples to gaze at, so next time you’re walking around Cheltenham why not see how many sash windows you can spot? Whether you want to upgrade your tired timber sash windows or replicate pleasing period window features, are you fully aware how uPVC sash windows work? Don’t worry if not, we’ll explain:

How do sash windows work?

1. Evolving from the simpler horizontal sliding sash window, vertical sash windows are constructed with two moveable window panels that slide up and down simultaneously; one in front and one behind. Able to open vertically from the top, bottom or both ways, it all depends on the style you’ve chosen.
2. The seamless vertical action of this timeless window design was originally counterbalanced by lead weights, attached to waxed cotton cords on either side of the window. These days, high-quality uPVC sash window equivalents utilise a spring balance system which has a similar counterbalancing principle. This method cleverly utilises a PVC tube that has two springs inside, allowing for effective counterbalancing. With Albany Windows, you have a choice of either style, depending on your home and individual taste.
3. Today’s modern uPVC sliding sash windows have a proactive tilt-in facility, for easy cleaning. Optional Georgian bars and sash horns are also available for the ultimate traditional sash window aesthetic.

FAQ: Sash Windows

What is the mechanism behind sash windows?

Sash windows use a counterbalance system that allows the panels to slide smoothly. Traditional designs use weights, cords, and pulleys, while modern versions use spring balances to hold the sash in place at any height

Why do sash windows stay open on their own?

Sash windows stay open because the internal counterbalance offsets the weight of the sash. This creates a balanced system, so the window can remain at any position without dropping or needing support.

Can both parts of a sash window open?

Yes, in a double-hung sash window both the top and bottom panels can move. This allows you to control airflow more effectively by letting warm air escape from the top and drawing cooler air in from below.

Are modern sash windows different from traditional ones?

Modern sash windows often replace weights and cords with spring or spiral balance systems. These take up less space, require less maintenance, and provide smoother operation while keeping the same sliding function.

Do sash windows improve ventilation?

Yes, sash windows are designed to improve natural airflow. Opening both sashes creates a circulation effect, helping to move stale air out and bring fresh air into your home without mechanical ventilation.
