Technical characteristics of the housing

Rigidity

Housing rigidity can be determined by deection measurement in mm per 1 m. of housing
construction at overpressure and under pressure, in values described by the standard. Higher
rigidity class means smaller deections of the housing.

Deflection (mm/1m) Class KMW-climat 40 KMW-climat 70

Heat losses

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