Sound Insulating Doors – Classified !

In danish building regulation, there is a specific requirement for the sound insulation of the door connecting a stairwell/hallway and a Living room.
Often times danish acoustic consultants will refer to the sound insulation classification of the door when defining the door in terms of its acoustic performance.
Luckily in the danish standard 1082 the classification of sound insulating doors is explained in a very short and simple manner.

This classification is something that door manufacturers often strive to fullfill as it helps both the acoustic consultants and the costumers.
Making it easier find the best solution in order to meet the requirements.
