Fire performance REI 60
maximum span = 5 m; maximum load Ed,fi = 4,0 kN/m²  
Classified by HFA  
Thermal performance U 0,17 W/(m2K)
Diffusion
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 HFA  
Acoustic performance Rw (C;Ctr) 34 dB
Ln,w (Cl)
Rating by HFA  
Mass per unit area m 56,0 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.
