Products  >>  Vertical Sliders

The Product
Due to the characteristics of the existing primary window, the Balanced Vertical Slider is the most complex type of secondary glazing system. It is applied generally to older properties with traditional sash windows.



How it works

The individually pre-tensioned spiral spring balances control the motion of the sash, enabling infinite vertical positioning.

This design provides ease of movement and has been specially developed to withstand decades of wear and tear. Tilt in versions can be pivoted through almost 180 degrees.

This is especially useful for cleaning but just as importantly can be crucial when considering fire escape requirements.

All variations of our exclusive secondary glazing styles are completely compatible. Each type can be easily used with another no matter what the application may be.
