Geprüftes/zugelassenes Bauteil

external wall awrhhi03a-10

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

Building physical assessment

Fire performance REI from inside
REI from outside 		60
30
maximum ceiling height = 3 m; maximum load Ed,fi = 19,2 kN/m  
Classified by HFA  
Thermal performance U 0,24 W/(m2K)
Diffusion adequate
Calculated by HFA  
Acoustic performance Rw (C;Ctr) 50 dB (-3; -10)
Ln,w (Cl)
Battens for the ventilation space screwed onto the structural timber together with vertical battens for the dry lining screwed directly onto the ledger beams will result in Rw(C;Ctr)=43(-1;-5) dB  
Rating by MA39  
Mass per unit area m 47,2 kg/m2
Calculation based on gypsum plaster board type DF GF
