Building physical assessment

Fire performance REI 30
maximum span = 5 m; maximum load Ed,fi = 2,6 kN/m²  
Classified by HFA  
Fire performance Germany
Classification: F30  
Load Ed,fi according to the German certification document
Proof: DIN 4102-4:2016-05, Tabelle 10.19, Zeile 1  
Thermal performance U 0,15 W/(m2K)
Diffusion adequate
Attention: Due to the application of a moisture-adaptive vapour barrier an object-related proof according to protection against moisture (diffusion) is mandatory. A hygrothermic simulation is necessary (e.g. WUFI)  
Calculated by TUM  
Acoustic performance Rw (C;Ctr) 51 dB (-4; -9)
Ln,w (Cl)
Assessed by Müller-BBM  
Mass per unit area m 156,7 kg/m2

Note

ATTENTION: Regarding protection against moisture an object-related proof in terms of paramter like e.g. climate, shading class etc. is required. Therfore a hygrothermic simulation is necessary (e.g.WUFI), a simple Glaser calculation ist not allowed.
