The special construction in connection with insulation and sealants achieves a high sound insulation performance. + Sealants High-quality sealants prevent noise from penetrating through gaps or joints. They are precisely matched to the frame and door leaf and thus make an important contribution to effective noise insulation. + Professional installation Only professional installation ensures that all components work together optimally. heroal specialist partners install your soundproofing door according to tested instructions so that soundproofing is ensured permanently and reliably.

DIN 4109 (soundproofing in building construction) specifies the minimum requirements for soundproofing in Germany. It defines six soundproofing classes based on the sound reduction index Rw. This value is given in decibels (dB) and describes the thickness to which a component insulates sound. The standard makes it easier to compare different sound insulation measures and gives builders a reliable guide. This allows you to choose the right soundproof door for your home - depending on the noise source, traffic volume and distance from the building. Use our interactive soundproofing tool to test the effect of the individual soundproofing classes and find out directly which level of protection is suitable for your requirements.

Only when the frame, door leaf and sealants are installed precisely can the soundproof door develop its full insulating capacity. This is why only trained heroal specialist partners carry out the installation - for reliable soundproofing in the long term. Find a heroal specialist partner >
dB (decibel) is the unit of measurement for sound pressure. The Rw value describes the sound reduction index of a door and indicates how much the sound is reduced. The higher the Rw value in dB, the better the soundproofing.
The sound reduction index Rw is decisive. It indicates how many decibels the noise level is reduced by the door. To make an informed choice, you should consider this value in relation to the background noise at your location.
