Secondary Double Glazing


 Secondary Vertical Sliding Sash Windows

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. It is particulary suited to the refurbishment and upgrade of the nation's architectural heritage.

How it Works:
The individually pre-tensioned spiral balances control the motion of the sash, enabling infinate 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.
