Benefits of secondary glazing
Secondary glazing is an effective method
of reducing noise pollution, whether you are looking to guard against
noise, road traffic, or retain noise, for example pubs and clubs.
How is Noise Insulation Achieved?
By increasing the gap, otherwise known
as 'cavity', between the existing window and the secondary frame, the
better the sound proofing becomes. We suggest a minimum cavity of 100mm
for increased sound reduction. Road traffic noise pollution can be
reduced by around 70-80% and can be reduced further by using acoustic
There is a wide range of glass options
available to ensure optimum sound reduction. The main objective when
aiming to reduce levels of sound pollution is to use glass which is a
different thickness to that in the existing window. By using glass of
different thicknesses, sound transmits at different frequencies, thus
improving sound reduction. Acoustic laminated can also be used, this has
a special interlayer, which is particularly good when trying to reduce
high frequency noise, for example aircraft noise.
Windows tend to be a prime area for heat
loss, which can be significantly reduced by introducing secondary
glazing. Improved thermal insulation can help to save energy and, in
turn, lower fuel costs.
Secondary glazing also helps to
eliminate draughts, improving comfort and reducing the level of airborne
dust getting into a building.
The use of secondary glazing can help to
meet the standards set out in Part L of the Building Regulations, which
are set to change in October 2010 with the introduction of Energy
Performance Certificates. These certificates will define a building's
energy rating and will become a factor in property valuations.
By introducing secondary glazing, even
with standard clear glass, you will improve the thermal insulation of
your home, but for optimum results use Pilkington K Low-e glass. 'Low
emissivity' (Low-e) glass such as Pilkington K Glass is designed to
reflect heat from fires and radiators back into your home, greatly
improving its thermal efficiency. Also, it allows heat from the sun
through your window, contributing to its energy efficiency. By using
less heat to keep your home warm, less energy needs to be produced,
therefore lowering the overall levels of greenhouse gases and the cost
of keeping your home warm.
Secondary glazing is ideal for period
properties, where window replacement is not an option. It is practically
invisible from the outside and unobtrusive on the inside, allowing
added comfort and security without disturbing the view.
