Saint Gobain Isover

Isover Saint-gobain

Alain Leconte

An acoustic building structure configured to be fixed to a framework of a building and including at least one first acoustic assembly that includes a panel of mineral wool and a bearer of the panel of mineral wool. The bearer includes a pair of one lower and one upper section pieces spaced apart by a spacing p and each of which includes a respective web each facing the other, and a respective flange bent at right angles to the associated web. The flanges are in one and the same plane and face towards each other. The panel of mineral wool is housed between the webs of the section pieces, and the acoustic assembly includes a rigid panel fixed against the outer faces of the flanges of the section pieces.

Acoustic building structure

In an acoustic building structure corresponding to the mass-spring-mass insulation principle, the two masses of the mass-spring-mass system are each formed of at least one rigid element (1,2) and are separated by at least one panel (4) of mineral wool combined with at least one air gap (5). The acoustic structure is such that the rigid elements (1,2) are trays with a U-shaped cross section and are lined on the inside of the U with at least one mineral wool (3).
