The effectiveness of reflective insulation (radiant barrier) is commonly evaluated by the reflectivity (emittance) of the surface with airspace facing to the heat source. This situation also occurs in the fur of animals and birds feathers, animal hair can employ the low thermal conductivity of small pockets of gas, so as to achieve the purpose of reducing heat loss. These materials can form gas cavities, which can be used to insulate heat with low heat transfer efficiency. The gas conducts heat much less than the solids. Most of the materials in the above list only retain a large amount of air or other gases between the molecules of the material. In a narrow sense, insulation can just refer to the insulation materials employed to slow heat loss, such as: cellulose, glass wool, rock wool, polystyrene, urethane foam, vermiculite, perlite, wood fiber, plant fiber ( cannabis, flax, cotton, cork, etc.), recycled cotton denim, plant straw, animal fiber ( sheep's wool), cement, and earth or soil, reflective insulation (also known as radiant barrier) but it can also involve a range of designs and techniques to address the main modes of heat transfer - conduction, radiation, and convection materials. It does not necessarily deal with issues of adequate ventilation and may or may not affect the level of sound insulation. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. Thermal insulation in buildings is an important factor in achieving thermal comfort for its occupants. It not only increases the load on the HVAC system resulting in more energy wastes but also reduces the thermal comfort of people in the building. This heat reduction and acquisition are usually unwelcome. Heat is lost or gained by transmission through the ceilings, walls, floors, windows, and doors. The rate of transmission is closely related to the propagating medium. Heat may be transferred either by conduction, convection, or radiation. The transfer of heat is caused by the temperature difference between indoors and outdoors. Thermal insulation usually refers to the use of appropriate insulation materials and design adaptations for buildings to slow the transfer of heat through the enclosure to reduce heat loss and gain.

Retrofitting buildings with further insulation is an important climate change mitigation tactic, especially in geographies where energy production is carbon-intensive. By installing insulation, building use less energy for heating and cooling and occupants experience less thermal variability. Insulation is an important economic and environmental investment for buildings. Often an insulation material will be chosen for its ability to perform several of these functions at once. for vibrations caused by industrial applications).

While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. Building insulation is any object in a building used as insulation for thermal management.
