Impoving Sound Insulation
Comfort and quality of life are directly dependent on the surrounding noise. People living in urban areas with increased traffic, are particularly affected by the harmful effects of noise. Noise pollution is everywhere - airplains, road traffic and other. With a choice of good insulating materials for facades, of great importance is the right choice of windows and window frames, whoose sound absorbing properties are well chosen. Of great importance for the level of sound insulation is the combination of profiles and glazing.
Glazing is over 60% of the window area, therefore the choice of glass is of utmost importance for achieving better sound insulation.
The maximum noise in a house should not exceed 60 dB. In comparison, normal human speech noise level is between 40-45 dB. Levels of noise protection are divided into classes, where the highest class is considered Class 6.
If you live up to 35 meters from a street, where approximately 50 cars are passing per hour, the standard double glazing (4 mm + 4 mm) would be enough to protect you from the harmful noise. The standard double glazing are soundproof class 2. Their glass thickness and the space between them are in the following proportion: Glass 4 mm - 16 mm distance - Glass 4mm- total thickness of 24 mm.
If you live up to 35 meters from the street, where approximately 200 cars are passing per hour, then you will need a glass with a protection class of at least 3. Then you will need a glass with at least two windows, as necessarily one of the lenses must have a greater thickness. For example, Glass 6 mm - 14 mm distance - Glass 4mm- total thickness of 24 mm.
Improving the sound insulation properties of the glass with different thickness of the glass is due to the ability to mitigate natural frequency, causing a drop of sound insulation in a frequency domain, and the principle of "mass absorbs noise", ie the greater weight of the glass (the greater thickness of the glass), results in better sound insulation.
Improving the sound insulation is achieved by increasing the distance between the panes in the glass frame, but this distance should not exceed 24 mm. . Also the argon gas filling not only improves the thermal insulation but also the sound insulation of windows.
To achieve better insulation of the abovementioned combination can be applied systems with up to 52 mm window frame thickness - triple glazing with different thickness of glass, as the same is to be filled with argon gas. This is applicable in LINEA Optima® - 7 ventricular system and Shcuco SI82 - six chamber system.
