What Is Sash Window?
A sash window, also known as a hanging sash window, is made up of one or more movable panels, or “sashes.”
Individual sashes are historically paned windows, but can now hold a single sheet (or sheets, in the case of double glazing) of glass.
Sash windows are vertically opening windows that are frequently identified with historical architecture and design.
A sash window is made up of two framed window sashes, one in front of the other. A sliding sash window is a more precise term for this type of window.
These window units are housed in frames with vertical grooves, allowing them to glide up and down smoothly without the risk of one frame rubbing against the other and harming them.
Counterbalances — weights on cords and pulleys – help the sashed move up and down. These counterbalances can be concealed within the frame or visible on the inside of the window.
Sliding sash windows lack hinges and have no outward swing, however some modern sash windows tilt to facilitate cleaning.
The sliding sash window has been around for almost three centuries, and the functioning mechanism has remained nearly constant. Some of the components, such as the staff bead and the separating bead, are still available for purchase.
Sash windows are designed to be readily disassembled for repair or replacement of damaged sash cords.
When issues arise, many people believe that the only viable solution is replacement – sometimes with contemporary plastic windows – which is simply not the case.
Because they have been carefully maintained and painted on a regular basis, some timber windows have survived for generations.
Plastic windows (PVCu) cannot be readily removed and repaired, and the components cannot be produced by any skilled joiner.
They have not been put to the test of time, yet there are already indications of failure
Plastic windows, which often come with double-glazed sized units, are only guaranteed for 10 years and are costly to repair if they fail.
Furthermore, they are built in such a way that they cannot replicate the mouldings and features seen in conventional timber windows.
Plastic windows, almost without exception, are completely unsuitable for use in any historic environment.
Sticking, joint failure, putty failure, damp rot, rattling, and draughts are the most common problems with conventional timber sashes.
Double Glazed Sash Windows
Double glazed sash windows are similar to regular sash windows, but they have the extra benefit of double glazing especially during the cold months.
Double glazing consists of two panes of glass rather than just one. Although it may appear to be a simple concept, installing double glazing is advantageous for a variety of reasons.
Sash windows with double glazing are an excellent choice for conservation zones or for individuals who want to keep the look and feel of a historic house.
You may choose between a genuine wooden sash appearance and a maintenance-free uPVC alternative in woodgrain treatments.
The cost of a standard original sash window double glazing can range from $600 to $1000, depending on the client’s needs, the condition of the sash, and the size.
The following are some of the primary advantages of glazed sash windows:
- Thermal efficiency has improved.
- Lower heating costs
- There is less outside noise coming into the house, and there are fewer draughts.
- Condensation on the interior of the window is reduced.
- Enhanced security
