Deciphering the Complexity of Adhered Veneer Wall Systems

Adhered veneer cladding systems have gained popularity in the past decade with increased use in all climates across the county. Today this type of construction is not only seen on high-end residential, but a common facade element on educational institutions, hospitals, airports and other commercial type buildings. While adhered veneer wall system have garnered the derogatory “lick and stick” label and are historically seen as economical, value engineering options, these systems have evolved significantly, as well as the codes and standards used to design and construct them. With the increased complexity of adhered veneer systems, deciphering the multiple building codes, standards, industry guidelines, and manufacturer’s installation instructions can be challenging. Drawing on WJE’s extensive experience investigating failures of these systems, this presentation will highlight code-compliance pathways, key resources available for design and construction, and general strategies to achieve a successful adhered veneer installation; inclusive of field testing and evaluation strategies.

Learning Objectives:

1. List the design requirements between prescriptive design versus engineered design for adhered veneer systems
2. Identify industry guides and standards (i.e., ASTM/ANSI) related to adhered veneer products and installation of adhered veneers.
3. Describe at least three of the most common failure mechanisms of adhered veneer systems.
4. Summarize key quality control steps to consider during construction that can lead to a successful installation.
