Operation

Spiral Balance

Spiral balance sash windows are a more modern window than that of the traditional weight & pulley option. Working with a spring on the jambs of the window, there is no need for a bulky box section of frame to encase a weight. This means that the sight lines of the sash windows are slightly slimmer which leads to larger glass area. 

 

Weights & Pulley

Weights & pulleys is the traditional way in which sash windows are operated. The system works with an iron bar (roughly the same weight as the sash) attached to a cord which rolls over a pulley and then attaches to the sash. This enables the sash to be slid up and down with relative ease. Because this system has to have a box section within the framework for the weight to be concealed in, the frame is thicker than that of the Spiral Balance system.

Glazing

Traditionally Sash Windows were made to only encase single glazed units, compromising thermal performance dramatically. Our modern day Sash Windows are available with either double glazed or triple glazed units which are argon filled to maximise thermal efficiency of the products.
