ACOUSTIC INSULATION BETWEEN FLOORS

Insulation of partition walls

The rigid contact between partition walls and floorings creates an acoustic bridge where noise is transmitted to lower floors and adjacent rooms. These transmissions can be interrupted by building partition walls on strips of 20 mm thick Celenit panels capable of supporting the weight of the partition without sagging, due to the strength and compression resistance of the panels. By building partitions over a continuous layer of panels, insulation can simultaneously be achieved against overhead and floor noises.

Insulation from floor noises.

Floating floors on Celenit panels. The reduced level of floor noises for a 25 mm panel is equal to 22 dB. By placing a layer of mineral wool under the layer of 25 mm Celenit panels, noise is reduced by 37 dB (DIN 4109), the highest possible level of reduction. However, a strip must be applied along the perimeter of the floor, measuring 20-25 mm in thickness and as high as the floor itself, in order to hinder the lateral transmission of impact noises.
Placing a continuous layer of Celenit panels between the floor structure and the floor does not only interrupt the transmission of sounds to lower floors, but also renders the floor temperature similar to that of the room, resulting in an increased sense of comfort.
