Brick is a natural insulator.
It’s slow to lose or absorb heat — which means your heater and air conditioner don’t have to work as hard to keep the inside of your home warmer in winter and cooler in summer. In fact, according to the National Home Energy Rating System (HERS) — an industry measure used to qualify homes for ENERGY STAR® ratings — brick homes are among the most energy efficient. Typical savings on your energy bill with brick are 2 to 8%. And you can take that to the bank.
