Timber sash windows – spiral balanced or traditional weights and pulleys?

Based just outside of Worcester, we’ve been had crafting timber sash windows for years and have come across just about every size and shape you could think of. When it comes to choosing sash windows, it can be tricky to know what type to go for. From colour and style to operating mechanism, it can be a minefield that leaves you confused about your options.

There are two main types of sash windows:

1. Traditional sash windows -weights and pulleys

In history, sliding sash windows were operated by cast iron weights. In this style of sash window, the weights are housed in boxes which sit at each side of the window. This is then attached to a piece of cord, which goes over a pulley system in the top corner of the window and attaches to the sash that will move. When the weight has been chosen to match the weight of the sash, the perfect counterbalance can be achieved to make the window glide effortlessly.

Traditional sash windows are generally a little more expensive but can be considered to have the best life span out of both options.

2. Spiral balance sash windows

This operating mechanism provides a modern and cost-effective alternative to traditional lead weights, and use similar principles of counterbalancing to stop the window from dropping. Although you can see the spiral balance mechanisms, these are generally cheaper and don’t require bulky weight boxes on the frame, resulting in a beautiful design that offers more light into the room.
