When the weighted sound reduction index required is Rw ≥ 32 dB, care must be taken in the design and on the building site to ensure that this value is actually achieved. Dimensionally stable frames and sound-insulating leaves are just as important here as the packing behind and sealing to the frames. If the seals do not close tight on all sides, even a high-quality door leaf cannot achieve a good level of sound insulation. 32 Doors with poor sound insulation often lead to subsequent measurements in the as-built condition.
