What materials are typically used in the construction of a party wall?

The correct choice highlights that party walls are often constructed using a combination of masonry block and wood frame. This mix of materials provides structural integrity and effective sound insulation, which are two primary functions of a party wall that separates two dwelling units.

Masonry blocks are robust and provide excellent fire resistance, while wood framing can help support additional structural loads and can be easier to work with in terms of applying finishes or attaching fixtures. This dual approach allows for flexibility in construction as well as insulation against noise transmission between the connected units.

While other materials such as wood framing and drywall, metal sheets and concrete blocks, or brick and plaster may be used in different types of construction or specific situations, they do not typically encapsulate the essential qualities and practical advantages of a party wall designed for duplexes or semi-detached homes.
