The
Dangers of Using Espag Handles on Tilt & Turn Windows
by
Winlock Security's Sales & Marketing Director, Philip Swann
According to the best estimates I have seen, sales of Tilt and Turn frames
in the UK are approximately 600,000 units per year. This figure is based
upon the consumption of gear but it is clear that sales of TBT handles
lag far behind. The only logical conclusion that can be drawn is that
many TBT frames are being fitted with standard espag handles.
You do not have to be Sherlock Holmes to determine that the main reason
for this is cost as espag handles generally cost only 25 percent of the
price of proper TBT handles. In certain circumstances, espag handles are
not only inappropriate but they create significant dangers.
The main deficiency with the use of the espag handle is that it does not
have a 'Tilt/Lock' facility. Proper TBT handles are designed and made
to prevent the handle going beyond the 90-degree position and, importantly,
the frame will go only to its 'tilt' position and not to 'turn.' TBT handles
are thus able to protect children and the elderly from the danger of falling
out of windows inadvertently opened in a multistorey application.
A
further benefit of TBT handles is that in public buildings windows can
be opened for ventilation purposes or kept closed for warmth without risk
to occupants and without the need for a restrictor.
Naturally, when the windows need cleaning a further turn of the key allows
the frame to achieve its fully open mode.
The best - but by no means all TBT handles - can also be key locked in
the closed position fulfilling the requirements of insurance companies
and giving the occupant added security. Specifiers should ask for this
as a basic requirement.
A Tilt and Turn window is usually bigger and heavier than a standard casement.
If it is fitted with an espag handle not only does it have to rotate through
180 degrees, but also it has to carry huge extra loads and torque for
which it has not been designed.
Remedial costs for site visits are too high to run the risk of under specifying.
Furthermore manufacturers' guarantees will usually be invalidated by the
use of espag handles in this situation.
I would advise extreme caution in the choice of window hardware for TBT
situations. Short-term gains can be quickly wiped out by the risk of litigation
if problems arise from the use of inappropriate handles. Keep your reputation
high and your customers happy in the long term, by specifying a handIe
that is properly designed and is 'man' enough for the job.
