Sustained moderate and high noise exposure can lead to health problems.
Noise can cause various diseases.
Hundreds of thousands of households are constantly exposed to significant noise from the outside environment, so windows and glazed surfaces are increasingly expected to provide protection from excessive noise.
Modern double glazing can play an important role, dampening the noise coming from the outside.
It reliably protects against the so-called.
It also protects against noise smog, which is now becoming a major burden on the body in big cities, along with air pollution.
The disturbing noise spectrum consists of several frequencies that vary in intensity.
Therefore, some frequency ranges are louder, which means that they are also more disturbing than others.
The choice of an appropriate noise abatement measure must therefore be guided by the source of the noise.
The same noise levels may require different noise protection measures – it always depends on the individual case.
Modern sound-insulating glass is constructed by combining glass of different thicknesses, using sound attenuation in the space between the panes.
It is also important to consider the shaping of the frame, the tightness of the joints and all the structural parts connected to the window.
The sound manifestations in the room are subject to this principle.
When the noise level is reduced by 10 dB, one feels that the noise in the room is half as loud.
LAMIGLASS SOUND CONTROL double glazing achieves superior results in sound insulation by the following means:
- at least one of the glasses has a large areal mass,
- different glass thickness,
- by increasing the distance between the glasses,
- by reinforcing the glass mass of individual panes, replacing these panes with special bonded panes.
| Type of glass | Airtightness [dB] |
| 4 – 16 – 4 6 – 16 – 4 8 – 16 – 4 | 32 34 36 |
| 10 – 16 – 4 4.4.2 SC – 16 – 6 4.4.1 SLA – 20 – 6 | 38 41 43 |
| 5.5.2 SC – 18 – 8 | 43 |
SC, SLA – type of noise barrier film
Note: When using units with highly asymmetrical plates and large interspaces, pressure variations will occur on individual plates as the weather changes.
When the panes have a large surface area, glass breakage may occur.
Optical distortion cannot be prevented.
To avoid this effect, it is necessary to use toughened glass.
