insulation
Material used to insulate something, especially a building, to prevent the loss of heat, the entry of noise, or the transfer of electricity.
Focuses on the barrier material itself (like fiberglass, foam, or cellulose) or the state of being protected.
Word relationships
- lagging: Lagging specifically refers to insulation wrapped around pipes and boilers rather than walls.
- shielding: Shielding is more commonly used for protection against radiation, electromagnetic fields, or physical impact.
- conductor: A conductor facilitates the transfer of heat or electricity, whereas insulation blocks it.
Commonly confused with
- isolation: Isolation is the state of being alone or separated; insulation is the physical barrier blocking heat, sound, or electricity.
