With advances in technology, it is now possible to get Sash Windows with double or triple glazing which offers excellent, previously unthinkable performances. As well as the advances in glazing units, Sash windows can now come with a "tilt function" which allows the sliding components to be tilted inwards for easy cleaning of external faces - perfect for multi story buildings.

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. Within the spiral balance range there is also an option to add a tilt function to the sliding sash. This enables the sliding sashes to be tilted into the room (hinged from the bottom) to allow for cleaning of the external facades from the inside of a building.

 

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.
