Technical characteristics of the housing
Rigidity
Housing rigidity can be determined by de?ection measurement in mm per 1m of housing
construction at overpressure and underpressure, in values described by the standard. Higher
rigidity class means smaller de?ections of the housing.

Heat losses
Measurement of heat losses from the housing determines thermal conductivity U. The value
of this parameter describes the thermal conductivity class of the housing. Lower U coef?cient
means lower heat losses through the housing.
