As the summer approaches once more, the large majority of us will be greeting the heat of the sun like an old, much missed friend. However, before the temperatures really begin to rise it would be wise to remember last year, when soaring temperatures brought the prospect of health problems and widespread discomfort associated with the heat. At Bygone, whilst our sash windows bring their own character and practicality to a property all year round, they’re particularly useful in summer. That’s because, by opening both the top and bottom sashes an equal amount, property owners can draw cooler air in at the bottom and vent hot air at the top, thus regulating internal temperatures.
However, we’ve noticed that some sash window users don’t take advantage of this technique fully, as they simply don’t understand how sash windows work. If this sounds familiar; don’t worry – we’ve briefly explained the technology used below.
The Basic Principle
Inside sash windows you’ll find a seemingly complex system consisting of pulleys and counterweights. The basic function of this technology is not to move each sash of the window, but to enhance and assist in their movement. The opening of the windows is made easier by the force of gravity acting upon the internal weights, and vice versa when closing the window.
It really is as simple as that; in many respects this aspect of sash windows has not changed much in hundreds of years for one good reason; it works. When this window form was first developed, cords, weights and pulleys could often be found on the exterior of the windows. However modern designs incorporate pretensioned spring balances, which can be accessed for maintenance purposes.
