This spiral balance sash window shows how the mechanism supporting the sash is inside the frame as opposed to hidden in the reveal.
Some sash windows do not have enough space in the reveal to house the weights to balance the sashes. In these cases a system known as a spiral balance is employed.
How does a spiral balance work?
There is a tube that sits inside the window frame containing a spiral shaped rod. This rod connects to a tension-ed spring that is adjusted according to the weight of the sash and provides the perfect balance. The sash will slide up and down with ease and stay open at any point, as in a traditional cords and weights sash window. Each sash will need a balance on either side to support it correctly.
Which is better – cords and weights or spiral balance?
Both systems are correct. It will depend on the style and build of your home as to which system will work for your windows.
Are spiral balances easy to adjust?
The spiral balances should pull the sash tightly closed. They can easily be adjusted or repaired. A specialist joiner, such as Timeless Sash Windows, will be able to advise you.
