Vertical Sliding
Aluminium Secondary Glazing

Vertical Sliding Aluminium Secondary Glazing

Our Vertical Sliding Secondary Glazing is ideal for providing thermal insulation and sound proofing for traditional wooden box sash windows, or any other windows that have horizontal bars. Panels slide up and down in the same way as vertical sliding sash windows and provide easy access to the existing window. When open they provide ventilation without interfering with curtains or blinds.

Our Vertical Sliders are extremely versatile, slide smoothly and are available with spring balances or spring catches to hold the sliding sashes in an open position. We can also provide vertical sliders with our unique tilt back facility.
