What’s so special about heroal soundproof front doors?

Soundproofing class 3

With soundproofing values of up to 39 decibels (db), aluminium front door systems by heroal meet the standards of soundproofing class 3. The sound insulation value largely depends on the door panel, the frame profile and the professional installation.

Design

Thanks to decades of expertise and specific components, such as sealants and insulations, we have developed a technically mature design which makes a significant contribution to the soundproofing of heroal front doors.

100 % foam filling

The profiles of heroal front doors are 100 % foam-filled. The special foam-filling process developed by heroal increases both thermal and sound insulation.

Which components provide for the best soundproofing for doors?

Mass

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

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

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

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.

Testing sound proofing classes for soundproof doors

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.

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.
