You searched for: “insulation
Any material or substance that provides a high resistance to the flow of heat from one surface to another.

The different types of insulation include blanket or batt, foam, or loose fill, which are used to reduce heat transfer by conduction.

Dead air space is an insulating medium in storm windows and storms as it reduces passage of heat through conduction and convection. Reflective materials are used to reduce heat transfer by radiation.
