serves the purpose of preventing the thermal energy provided by the heating cable set from
escaping into the surrounding environment
Insulation
U Values
coefficient of transmission
(How much heat escapes from the insulation into the environment).
Lower U Values are better
K Values
represent the thermal conductivity of a material. How well a material conducts
heat.
MgO 8 - 30 Up to 1100
CaSi 0.07 - 0.17 Up to 649
Cellular Glass 0.029 - 0.084 Up to 427
Fibre Glass 0.033 - 0.07 Up to 455
Polyisocyanurate (PIR) 0.022 - 0.035 -183 UP to 74
Mineral Wool 0.035 - 0.040 Up to 64
Examples
Low K values are better.
