Thermal insulation reduces unwanted heat loss and also reduces unwanted heat gain.
What is insulation?
Insulation creates a barrier between the hot and the cold object by reducing heat transfer by either reflecting light radiation.
Insulating materials are bad conductors of electricity and heat. So, insulating reduces the heat loss via conduction.
Thermal energy is prevented to increase the temperature of building in summers and decrease in winters. The thermal energy transfer plays vital role in insulating a building.
Thus Thermal insulation reduces unwanted heat loss and also reduces unwanted heat gain.
