Sash windows made in 1670 in England are still in use today. The concept was revolutionary in its time and proved immensely popular. So much so that more than 300 years later this style of window is still being used in buildings and homes around the world. This system comprises two framed sections that run along furrows sliding up and down in the outer frame by means of pulleys and a sash. Glass panes were often constructed with two rows of three panes each.
Over 300 years wood was used extensively to manufacture these glass frames and runners. Recently new innovative ideas led to materials such as aluminum being used in the manufacture of frames with great success. Sashes are normally constructed in single glazed pieces. However there are methods that can incorporate double glazing in the frame.
Wood is a wonderful material for this particular design but it is flawed. Even if well cared for and maintained wood is inclined to swell in damp conditions, weathers badly in extreme conditions and rots easily.
The fact that the sashes easily slide up or down is regarded as a weakness by security conscious people. Modern inventions and theft lock latches have radically changed the manner in which these windows can now be secured thereby removing the security problem.
New man-made materials and modern day metals require little or no maintenance. Aesthetically they appear the same but they are scientifically streets ahead of their wood counterparts. These new types seal tightly and prevent cold drafts entering and are therefore energy efficient.
Companies specializing in this field can restore, repair and replace frames quickly and efficiently. They guarantee their work and do the job with the minimum amount of disruption to a family's daily routine.
These sash windows were designed to cool rooms in a time when there was no electricity or air conditioning. Opening the top and bottom panels would allow free circulation of air in the room.
