A2. Insulation is a process of separating one thing from another. Materials for this are called insulators. Commonly we may insulate against the transfer of Heat, Electricity, and Sound or vibration.An Electrical insulator could be glass. Or most plastics.A Heat insulator could be a vacuum, such as in a vacuum flask. Or a loose material such as fibreglass wool.A Sound insulator is normally something of massive properties, such as gypsum wallboard, or concrete.The plastic covering on wire is a perfect example of an insulator.
