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.
