Question: 1 / 400

EIFS is a siding material that:

Is used in commercial buildings only.

Looks like stucco but lacks a wire mesh.

The choice stating that EIFS looks like stucco but lacks a wire mesh is accurate because EIFS, or Exterior Insulation and Finish System, does indeed resemble stucco in appearance but is constructed differently. It is a type of wall cladding that consists of an insulating layer of foam, a base coat, and a finish coat, often textured to mimic stucco. Unlike traditional stucco, which typically employs a wire mesh for reinforcement, EIFS relies on the rigid characteristics of the foam board insulation, which provides energy efficiency and moisture resistance.

This distinction is important as it highlights the unique properties of EIFS that set it apart from traditional stucco applications. Understanding this characteristic helps inspectors evaluate potential moisture intrusion issues, as the absence of wire mesh can impact the durability and susceptibility to water-related problems in its application.
