Frequently Asked Questions

How do sash windows work?

Sash windows consist of two panels. One (if single-hung) or both (if double-hung) panels move vertically to open and close the window. When a sash window is open, the glass in the panel stays in the same position. One of the windows is at the end of the cord, and the other end includes a counterweight to stop the window from shutting when the sash is released.

Should I get uPVC or aluminium windows?

This is entirely up to personal preference as both aluminium and uPVC have their own benefits. uPVC sash windows are insulating, so they will keep your home energy efficient. They are also durable, affordable, and need minimal upkeep.

Although similarly insulative, aluminium is slimmer and costlier. That being said, because aluminium is also more durable than uPVC, they do not need to be replaced as often. As a result, aluminium windows may be more affordable in the long term.

How should I measure my sash window?

Width: measure laterally from one side to the other while remaining within the box frame. Don’t take into account the width of the box within which the window is situated.

Height: Take into account both of the sashes when measuring from top to bottom. Measure within the box frame to ensure that your numbers are accurate.

Box frame height: start at the top of the window frame and measure down toward the windowsill.

Box frame width: this includes the whole frame of the window.

Which part of the window is the sash?

The sash is the part of the window that sits within the frame and retains the glazed panes so that they stay held together. If you have a double-hung window with two sashes, then both will move. However, if you have a single-hung window, then just the one sash will move.

How much are sash windows?

It is difficult to provide a price for your sash window as the material you choose, estimated fitting time, and other factors contribute to the overall costs. The best way to get a price is to call us at 01392 547272.
