摘要

Ceiling construction, especially for a ceiling arranged a distance away from a bare ceiling (R), against which a separating wall rests (T) comprises a support plate (1) provided with openings, a sound-absorbing layer (4) on the rear side of the support plate, and a covering layer (6) on the rear side of the sound-absorbing layer. Longitudinal sound-insulation is created in the region of the separating wall so that sound on one side of the separating wall passing through the ceiling construction and the cavity above the ceiling is insulated on the other side of the separating wall on passing from above to below. Preferred Features: The support plate is made of gypsum plaster board.
