Enjoy peace and quite at home?

Because windows not only let light inside, but also transmit noise from the outside, you may want to consider the Stratophone glass from the AGC range, which is a laminated glass that provides enhanced noise insulation in addition to its basic safety functions. The noise can be generated by unpleasant sounds from traffic, neighbours, children playing outside, etc. Safety laminated glass has a special acoustic film. Thus, the laminated glass captures sound and blocks the penetration of noise. How does it work? The special acoustic PVB (polyvinyl butyral) interlayer acts as a noise barrier, preventing the ambient noise from entering the quiet interior through the window. The higher the sound insulation of the glazing, the greater the user comfort you will feel, which has a positive effect on your health and well-being.

What are the main features and advantages of acoustic glass?

Sound insulation

The main function of the glass is to reduce the level of noise that gets inside. The glass is specially treated with an added acoustic film and thus it can significantly reduce the noise, improving comfort in both residential and commercial spaces. The glass is designed to effectively isolate the sound frequencies that are most disturbing to the human ear, such as traffic noise or construction work.

Multi-layer composition

Like laminated safety glass, noise control glass is made of layers where two or more panes of glass are bound by an interlayer that absorbs and muffles sound waves. This not only increases acoustic insulation but also offers other advantages such as better security or UV protection.

Combination with IGU

Noise control glass can be included in the double or triple glazing units. As part of the IGUs it provides not only thermal insulation but also excellent protection against sound waves, which makes it a comprehensive solution for energy-efficient and quiet living.

Improved quality of life

Noise can be a major nuisance that affects the quality of your sleep, your concentration and your overall welfare. The noise control glass significantly lowers the levels of ambient noise, especially in very noisy areas such as cities, busy streets or industrial zones. As a result, it contributes to the health and psychological well-being of residents.

Increased property value

Properties with noise control glass are highly valued, especially in densely populated areas. This adds to the comfort and attractiveness of the property, which can lead to a better valuation and increase its selling price.

Energy savings

The combination of acoustic glass with insulating functions (e.g. double or triple glazing) helps maintain a comfortable temperature indoors, thus lowering the need for heating in winter and cooling in summer. It ensures not only thermal and acoustic comfort, but also brings energy savings.

Protection of privacy

Acoustic glass muffles ambient noise and prevents the noise from spreading out of the building. This means increased privacy in residential, office or conference spaces.

Flexibility and design options

Acoustic glass is available in different thicknesses and can be combined with additional features such as solar protection or safety elements. It can be thus easily integrated into modern architectural solutions without compromising the aesthetics of the building.

All its features and advantages make the noise control glass the perfect solution for residential and other buildings, where the peace and quiet are of utmost value.

Look for Thermobel TG Stratophone or Thermobel TG Stratobel glazing in the AGC product range.

How does noise control work in windows?

Different materials process all waves, including sound, differently. A glass pane is a solid material with a flat surface, and as such will largely reflect sound waves, but because it is a thin layer, the sound waves can make it vibrate and thus transmit some of the waves further inside. In the spacer chamber of the insulating unit, the sound is slowed down by the gas content and it makes the glass it has just passed vibrate. Then the sound propagates further into the second glass in the closed chamber. The wider the space between the panes, the less synchronised the vibrations of the panes are (the vibrations of the inner glass are delayed) and the sound can be better suppressed. On the other hand, if the inner space is narrow, both panes vibrate with the same force and the noise is transmitted further inside. You can solve it either with asymmetric/different thicknesses of glass or by opting for laminated glass with a soft, i.e. absorbent PVB interlayer.     

Basic terminology

Noise protection is measured using three different values: the sound reduction index Rw (defined in EN 12758), which is measured in decibels (dB). Every sound is a wave, and the higher the waves, the louder the sound is perceived. From the low-frequency noise of slow traffic to the higher sound frequencies generated by children playing. Noise is further characterised by its frequency (number of waves per second), which is measured in Hz. With increasing frequency, the sound moves towards higher unpleasant tones. Loudness is also called sound pressure and is given in dB.

However, the most important thing in terms of noise perception is that the human ear does not hear all frequencies the same. The human ear can hear sounds between 1000 Hz and 5000 Hz best.
