Internal sound insulation doors
Design
In addition to their sound-absorbing properties, the doors in ComTür’s range of individual internal sound insulation doors offer tremendous design freedom and safety. There are minimum requirements that apply to the required airborne sound insulation of doors between certain areas and rooms to prevent sound from outside apartments and external work areas from penetrating inside. Depending on the specific area of use, these requirements are divided into the sound insulation classes SK1-SK4 with sound absorption values (Rw,P) of 32 dB, 37 dB, 42 dB and 47 dB respectively. Sound propagation is also prevented with a floor seal or a second level of sealing.
