# Insulated water meter boxes

Our insulating material has a density of 20 kg / m3. The following figures apply to the material at 0ºC, which is the relevant temperature.

The total insulating value is as follows:

Calculated only beneath the cover ( much better including the cover ). Thermal conductivity: 0,032 W/m  ºC ( 0,35 W/m  ºC of HDPE ).

 K 1: Cover                                    4,44 m2 x  ºC   Insulating value =                W                                 0,22 x W K – value =               m2 x ºC  Corresponds to 173 mm.
