external wall awrhhi13a-02

external wall timber frame construction, ventilated, with dry lining, with cladding

Building physical assessment

Fire performance REI from inside
REI from outside 		30
30
maximum ceiling height = 3 m; maximum load Ed,fi = 32 kN/m  
Classified by HFA  
Thermal performance U 0,20 W/(m2K)
Diffusion adequate
Calculated by HFA  
Acoustic performance Rw (C;Ctr) 48 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≥41dB
