Good conductor of heat:
Cooking pans, kettles, heat exchangers
Good insulator of heat:
Handles of appliances and utensils. table mats, woollen clothes, fibre glass
Fibreglass, felt and expandedpolystyrene foam are used for home insulation.It traps large amounts of air.This prevents heat from passing through the ceiling easily.
Why air?Reason: air is a poor conductor of heat.
