The structure is calculated for the worst snow and wind zone of Norway (sk = 9.0 kN/m², vb,0 = 31 m/s) and checked against the most severe regions of 22 European countries. Mountain regions pass up to the altitude shown; above it — a reinforced roof, calculated for your plot. The master copy is in English; the version for your country is issued in your national language with the order. Other countries and regions with heavier snow or wind — on request.
