In relation with the transition to European standards, as of March 2010 the standard CSN 73 00 35 Loading of structures becomes valid for the group of standards EN 1990 Basis of design, strength and durability and EN 1991 Actions on structures, constant, variable, extraordinary. The Czech versions of these documents are have been available since 2004-2008. The amendment in the map of snowy regions was received with a relatively high awareness. This amendment resulted in the appendixes CSN 73 0035 and BS EN 1991-1-3 Actions on snow, in effect since 1-1-2006. The current overlapping of CSN 73 0035 with CSN 1991-1-4 Actions on wind thus far, has not resulted in any critical reaction. This contribution should warn designers against an insufficient number of anchors for contact insulation, something that very often occurs. This number depends on the wind load, which in turn, is dependent on normative values. These are listed in a separate standard and are increasing, just like the snow loads.
