Fastening options Self-adhesive kit
Assembly recommendation Always attach the absorbers in the direction of the sound source/noise source for optimum effectiveness.
In order to avoid the elements grinding on the frame when opening the door, the parts are slightly shortened at the factory, so that they should be glued all around with a distance of 1 cm to the outer edge of the door leaf. A shadow joint of 1 cm should also be left between the individual elements. Detailed instructions for installation can be found in the supplied installation instructions.
Temperature­resistance - 40 °C to + 100 °C
Harmful substance information Mineral fibre free
Tolerance This high quality acoustic product is made on our precision machinery according to DIN 7715 Part 5 P3.
Notes on measuring To select your suitable door insulation set, you need the door leaf outer dimension. To do this, measure both the width and the height of your door leaf on the outside, i.e. on the side in the direction of which your door can be opened.
Why do I ALWAYS have to specify the external dimensions of the door leaf?
The door leaf outer dimension is ALWAYS specified as the nominal dimension (standard dimension) for doors. It does not matter whether you want to attach your door insulation set to the inside or outside of the door leaf. If you decide to mount it on the inside of the door leaf (inside the door frame), you will receive your set from us shortened so that it does not rub against the door frame.

Product variants For the sound insulation of a room door outside the frame, use our door insulation set for installation outside the door frame.

Absorption values

The measurements of the absorption coefficient were performed on polyester acoustic foams from RWTH Aachen. All values refer to absorbers with a size of 100 cm x 50 cm and were calculated according to DIN 52212.

3 cm
5 cm
125 Hz 0,10 0,17
250 Hz 0,50 0,73
500 Hz 0,78 0,71
1000 Hz 0,63 0,59
2000 Hz 0,49 0,57
4000 Hz 0,53 0,45
Sound absorber/ sound insulation in the reverberation chamber when calculating the absorption coefficients
Our aixFOAM sound absorbers have been tested for Hertz and pores in the reverberation chamber of renowned institutions such as RWTH University or the Technical University in Aachen. The sound absorption coefficients according to DIN 52212 stated above were calculated in extensive measurements.
