Closed sound-insulating wall - comprises profiled metal section with rolled supporting lip securing sound-absorbent material

摘要

The closed sound-insulating wall, roof, ceiling or floor section incorporates a profiled metal section with a supporting lip rolled into it. This secures sound-absorbent material facing towards the source of the noise. The panel construction is such that the sound absorbing material can be fitted at any time after the building itself is completed.
