insulation
意味: Material used to prevent the passage of heat, sound, or electricity. Also, the act of insulating or the state of being insulated.
Insulation is critical in construction, engineering, and electrical work. In buildings, thermal insulation (such as fibreglass, mineral wool, or foam) reduces heat loss and improves energy efficiency — a major focus of UK building regulations. Electrical insulation prevents current from flowing where it should not, protecting users from shock. Sound insulation reduces noise transmission between rooms. Figuratively, 'insulation' can describe protection from external influences or harsh realities.
