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.
In order to prevent the elements from rubbing against the frame when installed inside the door frame when the door is opened, the parts have been slightly folded in at the factory so that they should be glued at a distance of 1 cm from the outer edge of the door leaf all round. 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.
More information about this product is available, if required, in the accompanying datasheet. We are happy to provide you with this upon request.
The measurements of the absorption coefficient were performed on PUR-ES 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.
