maximum ceiling height = 3 m; maximum load Ed,fi = 32 kN/m  
Classified by HFA  
Thermal performance U 0,17 W/(m2K)
Diffusion adequate
Calculated by HFA  
Acoustic performance Rw (C;Ctr) 49 dB (-3; -10)
Ln,w (Cl)
If the battens of the ventilation level are screwed to the structural timber and the battens for the dry lining carried out vertically and screwed to the structural timber the result is Rw≥42dB
