Question
Why are hollow bricks used in the construction of cold storage rooms?
One Line Answer
Solution
Brick is a bad conductor of heat, hence bricks greatly reduce the conduction of heat from outside to the room. In order to ensure better insulation, bricks are made hollow so that air-filled between these gaps provides insulation to heat.
