The Operation of uPVC Sash Windows

Torsion balancing, a sliding mechanism, is how uPVC sash windows operate. A uPVC sash window allows for easy ventilation while maintaining a historic appearance.

The conventional sash windows from the Georgian era had an enhanced version of the sliding system. uPVC sash windows contain tubes that let the windows slide smoothly across vertical apertures. If there are any problems, it is very simple to maintain and repair the tubes inside the windows.

uPVC sash windows often come in two different styles:

    1. When a window is single hung, only one sash glides up and down.
    2. When both sash casements are double-hung, they can move vertically.

How Can You Measure the uPVC Sash Windows’ Energy Efficiency?

There are two different types of measurements used to rate a window’s energy efficiency:

Rating of Window Energy (WER)

This gauges the general energy effectiveness of a window. For instance, how much heat it lets in and how much it releases. The efficiency of windows can be rated from A++ to G, with A++ being the highest. Windows in England are required to have a rating of C or higher.

Your uPVC sash window’s rating is determined by its characteristics; for example, a double-glazed window receives a higher rating than a single-glazed window due to the various insulating layers. The official agency responsible for assigning uPVC sash windows a rating is BFRC.


An indicator of a material’s ability to behave as an insulator is its U-value. The material is more effective as a heat insulator the lower this threshold is.

A new double-glazed window’s U-value will be in the range of 1.2. Sash windows with triple glazing also get a lower grade. This rate will be greater if you choose a single-glazed uPVC sash window.

Along with the energy rating, other factors to consider include the size of your house, how you heat it, and the size of your uPVC sash windows. The amount of money you can save on your energy bills can be significantly influenced by all of these variables.

Alternately, the tile’s design might be different (called Georgian Variant). The options are essentially limitless.

Victorian sash windows

Two casement windows with two tiles each are included in the Victorian sash window. Alternative alternatives are available for this fashion. As an illustration, you may decide to have one casement window with two tiles and the other with just one tile.
