In Focus: Timber Sash Windows

The timeless style of timber sash windows has been a prominent feature of architectural history for over 300 years. Narrow sightlines, intricate profiles and periodic styling has maintained their position as the premium window style throughout their history.

Example Sash windows

Sash window refers to windows that are made up of one or more moveable sashes that open by sliding vertically or horizontally and are often found in Georgian and Victorian properties.

The George Barnsdale range of sash windows has been developed to maintain the features of the original windows, whilst drastically improving the performance. We have kept a common design for each opening type to enable them to be mixed within a property without standing out. We manufacture the following types of sash windows:

    Traditional Box Sash Windows

    s_traditional_box This window type is based on original designs that use cords and weights to enable the sashes to move either horizontally or vertically.

     Advantages:

    • Near perfect match for original windows.
    • Excellent opening mechanism that performs equally well with large, heavy sashes.

     

     


     

    Spiral Balance Sash Windows

    s_spiral_balanceThis window type achieves a similar appearance to traditional sash windows but uses a spiral spring balance to achieve a narrower frame profile.

    Advantages:

    • Narrow frame profile.
    • The best weather performance in the range.
    • The lowest cost option.

     


     

    Tilting Spiral Balance Sash Windows

    s_tilting_spiral_balanceThis window type is based on a similar design to the spiral balance option but enables the window to tilt inwards to allow for cleaning from the inside.

    Advantages:

    • Tilting mechanism, allowing for easy cleaning from the inside. 

     

     

     


     

    In addition to our traditional range, our traditional box sash and spiral balance windows are also available in our historic range. Yorkshire sash windows are also available in our historic range. Narrow profiles and historic sash moulds with a range of glazing options allow the windows to meet the requirements of heritage, listing and conservation requirements whilst retaining the high performance standards of our traditional range, including the use of double glazed units.
