For exterior wall systems, what is a common material used in the construction of walls?

Masonry is a commonly used material in the construction of exterior wall systems due to its durability, strength, and thermal mass properties. Walls made from masonry—such as brick, concrete block, or stone—provide excellent resistance to fire, weather, and pests. Additionally, masonry has a long lifespan with minimal maintenance, making it a practical choice for builders and architects.

The thermal properties of masonry also help in energy efficiency, as they can store and release heat, helping to maintain stable indoor temperatures. Its versatility in finish and design allows for a variety of aesthetic options while providing structural integrity.

In contrast, other materials like wood panels can be subject to decay and insect damage, while exterior stone, though aesthetically pleasing, can be more expensive and heavier, requiring more complex structural support. Plastic composites can offer benefits in terms of moisture resistance and weight, but they may not provide the same level of structural support or durability as masonry, particularly in load-bearing applications.
