    An attractive alternative to traditional sliding windows

    Runthru sash horns, which are top hung, create a great alternative to traditional types of vertical sliding windows. These windows are made by milling the profile into shape instead of screwing the runthru on as an addition to the sash. To finish off, a colour co-ordinated cap is used to cover the exposed end.

    Run Thru Horns Option 1

    Option 1

    RunThru Horn top hung over a fixed pane

    Top hung windows with horns, create an attractive alternative to the traditional vertical sliding window. Whilst this is the slimmest and most cost effective RunThru horn option, it does not meet the requirements of Part B of Building Regulations. In this instance Option 2 or 3 should be considered.

    Run Thru Horns Option 2

    Option 2

    RunThru Horn over Tilt and Turn inwards opening window

    The Upper Sash - The top hung casement provides a convenient and ready source of ventilation. It can also be locked in a night ventilation position. The Lower Sash - The lower sash is a Tilt and Turn window and as such can be tilted inwards for ventilation. It can also be turned 90° inwards for cleaning. Dependent upon size and position it can be used for emergency escape when the opening size must meet the demands of Part B of Building Regulations.

    Run Thru Horns Option 3

    Option 3

    The full Tilt and Turn with Dummy Sash and RunThru horns

    A window designed specifically for a home owner who requires the top opener over a fixed pane style, but has to consider Part B of Building Regulations. To match a top hung over fixed pane style window, a full Tilt & Turn sash is fitted with a fixed dummy sash with RunThru horns. The result is a fully opening window that has ventilation under normal circumstances and the escape facility if the worst should happen.
