Acoustic insulation material, is strips of mineral wool with a folding line formed parallel to the longitudinal axis, for insertion into the trapezoid profiles of a roof shell

摘要

To produce strip acoustic materials, to be laid within the trapezoid profiles of roof shells, they are of a mineral wool and preferably rock wool with at least one folding line parallel to its longitudinal axis. The folding zone is given elasticity by compression and decompression, before folding, preferably in the direction of the surface normal over a large surface area. The acoustic insulation is produced in a number of neighboring strips, where the winding axis is parallel to the longitudinal axes of the separate strips.
