Vertical Sliding
Aluminium Secondary Glazing

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.

Tilt Back Vertical Sliding Secondary Glazing

Our Tilt Back vertical slider was designed so that both sashes can tilt into the room for ease of cleaning. Our Tilt Back vertical sliders have balances to support the weight of the sash & hold it in any open position.

Our Balanced Vertical Slider has balances just like the Tilt Back that can hold the sashes in any open position. The frames are slimmer but as a result the sliding panels can not tilt inwards for ease of cleaning.

Our Unbalanced vertical sliders, also known as the "guillotine". Using the same profiles as our Balanced VS but minus the spring balances, instead spring catches hold the sashes up. These are our most affordable vertical slider.
