Features & benefits

Timber sash windows could be of two types, traditional cords and weights or spring balanced. The difference between them is primarily the box size, 100mm in the case of cords and weights, and 60mm when talking about spring balanced. Apart from that there are no differences between those two types of windows. All of them can go with stuck on astragal bars of different sizes to accommodate the requirements. By default sash windows are with cords and weights but occasionally depending on the openings we suggest spring balanced sash windows to facilitate smoother replacement.

  • What does a sash window look like?

    A traditional sliding sash window is a good option for a residential dwelling because a full pane of glass only has to be lifted instead of opening outward. A sliding sash window can be manually operated using a pole or crank, or mechanically by the use of weights and cords.

  • How long do wooden sash windows last?

    Although there is no standard time frame, many timber sash windows have lasted a hundred years with regular maintenance. For the best quality window with a lifespan of around 25-30 years, you should look out for simple features such as a weather proof lip on the edge or high quality seals, as well as an old fashioned cross bar for ventilation.
