Thermal insulation is the process of reducing the heat transfer between surfaces using special materials in order to prevent the cold air in the exterior environment from causing temperature loss in the interior environments in winter months, and hot air in the exterior environment from causing a temperature increase in the interior environments in summer months.
In order to balance the temperature in houses, owners try to increase the temperature using fuels like natural gas and coal in winter, and decrease the temperature using air conditioners or similar cooling appliances in summer. Homeowners consume a certain amount of energy during all these heating and
cooling processes. Unfortunately, more than half of the energy which is used for heating purposes in buildings is lost when there is no thermal insulation.
