Assignment of additional measures for the Ergoldsbacher Forma®
According to the Central Association of German Roofers’ pamphlet on sub-roofs, sub-coverings and under-bracings, and the basicregulations of the Roofers’ Guild, regular roof pitch 22°, minimum roof pitch 10°, according to the state of technology.
Country-specific building standards and/or regulations must be adhered to, if no other contractual agreements have been made.
Increased demands due to:
- long spar lengths (longer than 10 metres)
- concentrated water channel on parts of the roof surface, e.g. under drainpipes, where valleys form junctions and the like
- special roofs like cambered dormer windows or arched and conical roofs
- snowy regions ≥ 1,5 kN/m2 of ground snow load - windy regions in wind load zone 4 or in ridge or hill-top positions or where gullies form
