The traditional sash window and its double glazed reinvention

Box 'sash' windows with traditional sliding sash designs and timber construction are the classic type of window which is often found in Victorian, Edwardian and Georgian properties in the UK.

Sadly, due to neglect as well as wear and tear, these windows received a poor reputation which was unwarranted. This eventually resulted in many examples being ripped out and replaced with uPVC windows in great numbers during the 60s, 70s and beyond.

Today, many homeowners are minded to keep the classic look of their houses as they were originally intended to appear. Improvements in materials and designs, including the availability of fully doubled glazed units, has meant that the sash window is currently enjoying a great comeback in popularity – gaining a modern reinvention.

What is a sash window?

A sash window (sometimes called hung sash window in the United States) is made of one or more movable panels that make up a frame around panes of glass. The term is used mainly to refer to windows where the panels are opened via a vertically sliding motion.

This enables a fully effective opening at the bottom or the top to give a variety of choices. The weight of the glazed panel frame is balanced by a heavy counterweight which is hidden in the window frame where it meets the walls. The weight then connects to the window by a sash cord or chain running over a pulley at the top of the frame.

Traditionally sash windows were made of softwood with single glazed glass, leading to potential problems with rot and distortion of the woodwork boxes and frames. One strange advantage of sash windows is that it is possible to clean all the glass surfaces from the inside by arranging the sliding panels in different combinations of positions.

Modern sash windows

Although many original fittings have been torn out and replaced over the years, there is now a healthy market is retro fitting replacements. Recently, uPVC sash windows have come on the market, appealing to those who like the advantages the modern materials offer. This is why reputable double glazing experts such as Safestyle UK offer window frames in a number of styles and modern materials.

The new sash window has eradicated the problems of the original versions, with new unbreakable cords fitted, retaining beads with integral draught excluders included, and key operated locks often provided as standard.

Also, new units are often double glazed; depending on local building department planning restrictions. Between the glass panes is clear, inert Argon gas which acts as an extra insulation barrier – making these windows environmentally beneficial as well as traditionally styled.

Whether you choose to go for modern materials or new wooden look versions, double glazed sash windows are a practical and great looking way to enhance the look of your property whilst keeping you cool in the summer and insulating your home in the colder months.
