Which brick type is suitable for cold weather but not wet conditions?

• A. SW brick
• B. NW brick
• C. MW brick
• D. BW brick

Answer: (C)

Weather resistance classifications guide how bricks perform in different climates. In cold environments you need bricks with good frost resistance to withstand freeze–thaw cycles, and in wet conditions you want bricks with low water absorption and durable performance when soaked. A brick rated for moderate weather exposure is designed for climates that experience cold but not heavy, persistent wet exposure. It provides enough frost resistance for cold spells while not being optimized for constant moisture, making it suitable where winters are dry to moderately wet but not extremely wet. If the wall were to face heavy moisture routinely, a severe-weather brick would be preferred for its lower porosity and better water resistance.
