ABSTRACT:
Core material for use in building elements in which the interspace between the outer layers is filled up with a porous material comprising at least two layers which are interconnected on a minor part of their surfaces facing each other, preferably by glueing. According to the invention the core material consists of two layers of bonded mineral wool the surfaces of which are touching each other, the interconnection being along the edges. The core material reduces sound transmission without substantially reducing mechanical strength.
