Today's world is one of noise. Traffic, trains, aircraft, machinery, appliances, television and music systems - sound comes at us from everywhere, much of it unwanted
Whatever the noise source, the correct selection of glass for
the window systems and construction method are crucial for a
peaceful environment. Once the required sound reduction is
established for the application a glass type and thickness can be
selected. For example, street noise is 70 dB while a bedroom
requires 35dB: therefore 70 - 35 = 35dB of sound reduction required
in the windows (and walls).
Double Glazing
GlassTech insulating glass units can be used to reduce noise if
the glass is of appropriate thickness and type. In addition,
laminated glass can be combined in an IGU for ultimate sound
control.
Laminated Glass
While toughened, wired or patterned glass behaves acoustically
the same as standard float glass, laminated glass reduces sound due
to the vibration-dampening effect of the interlayer inbetween.
Special acoustic grades of laminated glass are available such as
SoundStop which is a special acoustic CIP-laminated glass
consisting of two glass sheets with a layer of acoustic resin.
