DLD is designed for low air resistance with baffle combinations that attenuate particularly low-frequency noise well.
The type of insulation material has been developed to provide good noise properties, low weight and to be cleanable.

DLD meets the requirements of air tightness class C and pressure class 2 according to EN 1507:2006.

DLD is equipped with joining profile type RJFP or LS.
