lifted off

main window

Internal Secondary
Glazing can be a cost effective solution if the main window
is essentially sound and in good condition but there is a
requirement to improve thermal and/or noise insulation.
Secondary Double Glazing is suitable for all Conservation Areas and
(subject to listing detail)
Listed Buildings.
If the main reason for
considering Secondary Glazing is for sound
insulation, please see further information below.
Noise Insulation
Where noise is a really serious nuisance, in areas of heavy traffic
or close proximity to railways and for properties on flight paths,
Secondary Double Glazing can be upgraded to provide a significant
level of transmitted sound reduction.
This is achieved by using Stadip Silence ® laminated glass, with a
special acoustic PVB interlayer which acts as a dampening core
between the two panes of glass. This prevents vibration and
eliminates the problems of critical frequency transmission and high
frequency acoustic peaks.
The PVB interlayer is transparent and colourless, thus resembling
normal glass.
It is impossible to give exact figures for noise reduction in a
particular situation without instructing a Consulting Acoustic
Engineer to attend site and take measurements. This is because each
situation will depend upon the different types of noise, direction,
distance, etc. This would not be cost effective in a normal domestic
situation.
However, as a good 'rule of thumb', fitting Stadip ® secondary
double glazing inside a single glazed window would more than halve
road traffic noise.
