More peace and quiet with a heroal soundproof door, because it insulates sound by up to 39 decibels.
Effective noise reduction for more quality of living conditions
What’s so special about heroal soundproof front doors?
Which components provide for the best soundproofing for doors?
Mass - The higher the mass of a door, the better its soundproofing effect. Heavier doors make it easier to reflect incident sound waves for higher sound insulation values.
Door leaves - Since single-layer components have to be very heavy to achieve sufficient sound insulation, multi-layer components are often used instead. In this way, a structure with a comparably low weight can achieve higher sound insulation.
Door frame - The construction of heroal doors ensures that the door frame reflects and absorbs sound waves. heroal acoustic door frames are made of aluminium, which allows them to achieve optimum soundproofing values.
Sealants - Since sound waves pass through the smallest openings, there is no insulation without sealants. Acoustic and rebate sealants make sure that both door sash and door frame are tight, just as the sealants between door and floor.
Installation according to tested installation instructions
Installation according to tested installation instructions - Even the best soundproof door will not work without proper installation. Qualified installation by our specialist partners ensures effective sound insulation.
The right soundproof door for every requirement
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.
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 insulation may differ from the audio examples.
