How to use insulation
Insulation is used in construction, engineering, and physics contexts to refer both to the materials themselves (fibreglass insulation, foam insulation) and the process of applying them. It commonly appears in discussions of energy efficiency, building standards, and thermal management. The term can be metaphorical when discussing emotional or social separation, though this is less common.

A common mistake
Learners sometimes confuse insulation with isolation; while related, insulation specifically emphasizes blocking the transfer of heat, cold, or sound, whereas isolation means separation or being alone.
