More peace and quiet with a heroal soundproof door, because it insulates sound by up to 39 decibels.
Test the sound insulation
Test the noise reduction of the sound insulation classes that heroal windows (sound insulation classes 1 - 5) and doors (sound insulation classes 1 - 3) 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.
