As you walk past a building you wont look at what window types they are. Old houses like Victorian and Georgian hold sash windows. They are made up of one or more removable panels so if you look closely you can see them. In less scientific terms they are squares split across a window. Nobody really knows where the sash window was exactly invented all we know that is it one of Britains best inventions and most historic.
Sash windows have a history that goes way back to 400 years ago. Timber was the first material used as others were not developed enough and not cheap to make. Many homes possessed them and they are still as new now as they were back then. They still are brilliant and stylish. Its not really until the past 30 years where the material of sash windows has varied. Aluminum is a popular material used that make a large number of sashes. There were a lot of complications when making the first wooden sashes. The problems people had were the rotting woodwork and the head banging noise that was the window smashing against its frame as you tried to get a good nights sleep.
You may be thinking how are they this popular. One advantage of using them is they are ideal for the terrible weather us brits experience year in and year out. As they are opened vertically the rain cant get in. You may wonder how sash windows face up against hot weather as well as cold. When the temperature increases they give fantastic ventilation as the warmer air goes out the top and the remaining cool air is passed through the bottom.
Its also possible to clean all of the glass within the building it is in by sliding the panels to different positions.
During the 1980s the first modern sash windows were produced and they wanted them to look like timber sashes as much as they could to preserve that old look.
Many think that uPVC sash windows
are still popular as they were then because they are attractive. They have made history in British engineering as they are a simple structure and very elegant.
