Spring Balance Sash Window

The spring balanced sash window  is often used in new builds where a flush reveal has been detailed by the architect. It is an economical option; developers regularly incorporate spring balanced sash windows where the build costs need to be competitive. This is a good option for those looking for a window that is historically accurate and pleasing to the eye.

These timber windows are factory double glazed as standard, fully weather-stripped and supplied factory finished to site. We offer you the option of a supply and fit service to ensure there is only one point of contact.
