With heroal soundproof windows, you can reduce the sound level by up to 48 decibels (dB) and make a huge improvement to your quality of living.
Laminated glass panes
Laminated glass panes - Laminated glass panes have an elastic interlayer between two or more layers of glass and increase the noise insulation of windows.
Various pane thicknesses
Various pane thicknesses - Sound-proof windows have a different thickness of glass on the panes. The higher the difference in thickness of the inside and outside pane, the higher the noise insulation.
Air gap - The air gap between the individual panes has to be wide enough, so that the vibrations of the outside pane are not passed to the inside pane. Special materials for the air gap, such as PVB films or casting resins, absorb sound and only pass it on at reduced values.
Mass - The higher the mass of a pane, the less it vibrates. More sound waves hitting the pane can be reflected. Therefore, thicker and hence heavier panes generally reach a higher noise insulation value.
Installation according to certified installation manual
Installation according to certified installation manual - If sound-proof windows are not professionally installed, their noise insulation values may easily decrease by some decibels. Our heroal specialised partners make sure that your sound-proof windows are professionally customized and sealed in order to reach optimal sound and noise insulation values.
Material for window frames and sashes
Material for window frames and sashes - The material aluminium stands out for its insulation values and is perfectly suited for sound-proof windows.
Design of window frames and sashes
Design of window frames and sashes - The window frame is an essential part of efficient sound insulation. heroal window frames are foam-filled. Therefore, the window frame reflects and absorbs sound.
Comparison of windows with and without sound insulation
Test the noise reduction of the sound insulation classes that heroal windows can provide. You can use the slider to simulate the different sound insulation classes. Please turn on your speakers – with sound insulation class 0 the noise should be perceived as unpleasant.
Current sound insualtion class 0
Meaning of sound insulation class
The sound pressure level is reduced by 25 - 29 dB(A), the noise protection is very low.
The sound pressure level is reduced by 30 - 34 dB(A), which results in low noise protection.
The sound pressure level is reduced by 35 - 39 dB(A), which results in moderate noise protection.
The sound pressure level is reduced by 40 - 44 dB(A), the noise protection is perceived as good.
Very good noise protection is achieved by reducing the sound pressure level by 44 - 49 dB(A).
Extremely high noise protection by reducing the sound pressure level by 50 dB(A) or more.Note: The actual sound insukation may differ from the audio examples.
Depending on the requirements, heroal soundproof windows can be upgraded as high as sound insulation class 5, which allows them to meet the highest sound insulation demands. Try them out for yourself. We would be happy to give you more information about the right acoustic window for your needs. Give us a call, visit our specialist partners and let us inspire you.
