What might a cavity wall be built off?

A cavity wall is typically built using masonry units, which are blocks made of materials like brick, concrete, or stone. The construction technique involves two layers of masonry with a hollow space, or cavity, in between. This design provides several benefits, such as improved insulation, moisture control, and structural stability. The cavity effectively allows for drainage and prevents water penetration, making it particularly valuable in climates where moisture management is critical, like in Alaska.

Using masonry units also contributes to the wall's durability and resistance to various environmental factors. In contrast, while reinforced concrete panels, wooden frame structures, and metal studs can be employed in different types of wall assemblies or construction techniques, they do not reflect the traditional construction style referred to specifically as a cavity wall, which is characterized by its two-layer masonry system.
