Geprüftes/zugelassenes Bauteil
flat roof fdroba01a
flat roof timber frame construction, not ventilated, with dry lining, suspended
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.
