What Are Sliding Sash Windows?
Sliding sash windows have been a popular style since way back when, the end of the 16th century to be precise. Beautiful traditional timber sash windows are loved as much today for their ability to combine distinctive style with modern technology. Their ability to retain aesthetic appeal and the stunning original features of a property whilst offering the thermal efficiency of double glazing makes them ideal for homeowners of period properties.
Sliding sashes are vertically opening windows consisting of two framed window sashes. One sash is positioned in front of the other and they sit in frames with vertical grooves that allow them to move up and down smoothly without any danger of one frame rubbing against the other and damaging it. The up and down motion of vertical sliding sash windows is assisted by weighted cords and pulleys which can be hidden within the frame or exposed on the inside of the window if preferred.
What are Glazing Bars?
The glazed area of the window is made of smaller panes of glass joined together by horizontal and vertical wooden pieces called glazing bars. This creates the traditional English window effect associated with Georgian and Edwardian architecture.
Glazing bars were originally required because the glass making technology of the time was somewhat primitive. Windows were made by traditional glass blowing techniques. The pane of glass was made by blowing a cylinder which was then cut and rolled whilst still very hot. Because the panes of glass were only very small, big windows were made up of lots of smaller panes of glass joined together by the windows bars.
What are the different types of sash windows?
Sash windows were invented in London in the middle of the 17th century, at least the style of sash windows that we know of today. The French had versions of sash windows from the 13th century.
This beautiful window style went on to transform British architecture for hundreds of years. The three main styles of sash windows represent the eras in which they were most commonly used: Georgian, Edwardian and Victorian.
Why is it called a sash window?
This type of window simply comes from the term that wood joiners used for the window itself. A sash window comprises a frame and a ‘sash’ (the window bit). As sash windows were originally invented and used in France, the term ‘sash’ likely comes from the French joiners that brought the windows over to England.
Which part of the window is the sash?
The sash part of the window is everything that isn’t the window frame itself. So it is the part of the window with the glass, glazing bars and the part that you would lift up or down when opening the window.
The other part of a sash window is the frame, and inside the frame are the weights and cords that connect to the windows to help you lift them and keep them stationery.
Suited to homes in conservation areas
We have been designing, manufacturing and installing high quality sash windows into hundreds of property types over the many years we have been in business. Our skilled joiners understand how important it is to retain the original elements of period homes and will be able to advise on what will work for the type of property you reside in, whether you are repairing original timber sash windows (inserting new glass into the existing window frames so you can retain the existing windows) or replacing everything completely, we will ensure the windows we craft retain the authenticity and practicality you need.
Energy efficiency
Some people mistakenly think that they need casement windows to improve thermal performance, but this isn’t the case at all. You don’t need to install uPVC sliding sash windows either. Technology has come a long way and new wooden windows will offer you excellent, energy efficient windows without compromising on the charm and style of your home.If double glazing hasn’t been permitted by your planning department (this may be the case if you own a listed property or live in a conservation area), fear not, we can talk you through other options.
Smooth to open and easy to operate
We make everything bespoke so we can guarantee precise engineering to ensure smooth running. Our sliding sashes are easy clean and effortless to open.
Better Ventilation
Because sliding sash windows can open at the top and bottom at the same time they provide excellent ventilation. Having an aperture at the top and bottom creates a convection flow of air that will cool a room wonderfully in the summer. This convection flow will not only cool and aerate your home, but it will also help remove dust.
