  • Radiant Transfer of Heat– Under the radiant transfer of heat, the heat is transferred because of the electric waves inside the property. 
  • Conductive Transfer of Heat– Under the conductive transfer of heat, the parts of a building get heat because of physical contact like touching. 
  • Convective Transfer of Heat– Under the convective transfer of heat, the heat gets to the property through the flow of hot air or liquid within the premises.

As the sources of heat are different, the thermal insulation providers and suppliers have to ascertain the main source of heat transfer and deal with it accordingly. The barrier created by the insulation sheets helps in keeping these sources of heat at bay and reduces their impact. 

Selecting the Type of Heat Insulation Material

Lastly, you need to determine the type of insulation material to be installed. There are different types of materials like fiberglass, cellulose, aluminum, etc. Different materials show different levels of insulation. For example, fiberglass provides fewer levels of insulation. Hence, once the level of heat management is decided, the heat insulation material is also decided to protect the premises. 

So this is how thermal insulation is done and works in any premises. Now you know how every step of the process provides a different result. And, how every step is important to maintain the desired temperature.
