Glass Soundproofing

Our soundproof windows combine excellent acoustic performance with the benefits of conventional laminated glass. Thanks to Acoustic PVC foil, specially designed, this type of glass provides a measurable improvement of the sound insulation coefficient. It can be used in combination with other types of functional glass to give you the perfect combination of insulating glass.

The traffic noise, the construction site across the street, the trains passing in the area, the environment you live in can be noisy and annoying. This is not only
inconvenient, but
constant exposure can produce sicknesses.

Glazing range

The range of soundproof windows includes windows with double or triple layer of various thicknesses,
which are composed of laminated glass with PVB or ACCOUSTIC PVB foil.

How loud is too loud?

Diseases caused by noise exposure are determined by the sound intensity and the duration of exposure. The maximum permisible sound level
is 85 dB over a period of 8 hours. Some examples of noise are listed below:

DATA SHEET

The Rw coefficient (dB) The acoustic attenuation index is relevant for the acoustic properties of a glass. It shows the difference in sound levels on both sides of the glass, for a normalized noise spectrum (for example road noise). A high value indicates a good soundproofing.

In the above charts you can see the impressive effect of sound waves absorption for a
laminated glass with simple PVB foil, respectively with Acoustic PVB foil.

How does it work?

There are five factors that contribute to a soundproof window:

Glass mass - if the glass is thicker, the sound insulation is better
Asymetric -
the glass sheets must have different thicknesses
Distance between glass -
if the space between the glass sheets is larger, the glass is more efficient
Gas enviroment -
replacing air with argon increases soundproofing performance
Using laminated glasses -
the glass laminated with PVB foil or with Acoustic PVB (SLA) foil dampens sound waves better than monolithic glasses
