Secondary Glazing Balanced Vertical Slider
The Black Knight balanced vertical slider has been designed to copy the sliding motion of a traditional sash window and each individual sash is supported by pre-tensioned spiral balances which allow the panels to be opened in a variety of positions.
Secondary Glazing Tilt-in Vertical Slider
When access to an existing sash window is difficult the secondary glazing can be manufactured to include a tilt-in facility which lets the sashes be pivoted into the room for cleaning and maintenance of the existing primary window.
Secondary Glazing Horizontal Slider
Horizontal sliders can be manufactured in combinations including 2, 3, 4 & 5 panels and each one of the individual glazed sashes can be removed to allow for easy cleaning and maintenance of the frame of the existing window.
