Answer :

Final answer:

Expanded metal or wire lath with a backing of building paper serves as a strong base for plaster applications and as a moisture barrier to protect structural elements in construction.

Explanation:

The purpose of expanded metal or wire lath with a backing of perforated or building paper is to act as a sturdy substrate for plaster, stucco, or other cementitious materials in construction applications. The wire lath provides a mechanical key that allows the plaster to grip and hold onto the surface. Additionally, the building paper acts as a moisture barrier, preventing water from seeping into the structural elements of the building while still allowing the passage of air and moisture vapor for breathability.

This system is commonly used in both exterior and interior applications, providing both structural integrity and weather resistance. The expanded metal or wire lath ensures that the plaster remains intact and adheres well to the structure, while the building paper protects the building materials from potential water damage.
