INSULATED WATER METER BOXES
Our insulating material has a density of 20 kg / m3. The following figures apply to the material at 0 ºC,
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. Mineral wool. |
K 2: Conic ( average )
2,06 m2 x ºC
Insulating value = W
0,48 x W
K - value = m2 x ºC
Corresponds to 80 mm. Mineral wool. |
K 3: Vertical ( average )
1,43 m2 x ºC
Insulating value = W
0,70 x W
K - value = m2 x ºC
Corresponds to 55 mm. Mineral wool. |
