Results for “what is insulation” · retrieved September 22, 2026
Insulation is a material used to prevent the transfer of heat, sound, or electricity, or the act of applying such materials to protect a space or object.
Answer details
Thermal Regulation
It resists heat flow, helping to keep buildings warmer in winter and cooler in summer, which reduces the energy needed for heating and cooling systems.
R-Value Rating
Insulation is rated by its R-value, which measures its thermal resistance. A higher R-value indicates greater effectiveness in resisting heat transfer.
Types of Materials
Common forms include batts, blankets, loose-fill, and various types of foam, which work by limiting air movement and conduction.
Broader Usage
The term can also refer to the state of being isolated or protected from external factors, such as economic conditions or noise.
