T 56 (cavity of approx. 56 mm):
+ 1x plasterboard: rw = 69 dB
+ ILLFORM heavy film (3.5 mm, 8 kg)
+ 2x plasterboard: rw = 73 dB
T 96 (cavity of approx. 96 mm):
+ 1x plasterboard: rw = 73 dB
+ ILLFORM heavy film (3.5 mm, 8 kg)
+ 2x plasterboard: rw = 75 dB |
The battens are fixed directly into the existing construction.
A first plasterboard sheet is then screwed against these battens, a heavy foil type Illform is glued and a second plasterboard sheet is screwed. The space between the slats can be filled with acoustic cavity insulation for an even better absorption efficiency.
