Vertical Sliding Secondary Glazing

Our vertical sliding secondary glazing is ideal for heat and sound proofing for traditional wooden box sash windows, or any other windows that have horizontal bars. Panels slide open 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 sliding secondary glazing is extremely versatile, slides smoothly and is available with spring balances or spring catches to hold sliding sashes in an open position. We can also offer our unique tilt back easy clean vertical sliders.
