![]() ![]() Unlike a cavity wall masonry veneer, where loading is placed on a brick shelf or a supporting lintel, the adhered masonry veneers are supported by attachment between the lath system and the structural substrate and the bond to the thin veneer material to either the concrete masonry back up or the attached lath. When the designer requires an adhered veneer and rigid insulation, this can be accomplished when section details are considered at the early stages of the project and should be an easy part of the wall design. The weight of the veneer can usually be obtained from the material supplier so the design professional can properly size structural wall components early on in the design process. This was a big change order that could have been avoided for the owner of the designer would have held to original material choices. I mention this because I once had a job where the designer changed the veneer and framing had to be increased to handle the eccentric load of the veneer. Thin veneers can range from 3 to 25 pounds per square foot (PSF) when applied to the wall, a wide range that must be considered when sizing the dimensional framing members. Parts and Pieces of the Adhered Veneer WallĪvailable thin veneers can be thin natural stone, thin brick, thin cultured stone, or synthetic veneer systems. Our discussion will cover basic materials used in residential and light commercial construction of a stud constructed structural substrate. We will look at the differences between a cavity wall and an adhered masonry veneer. Increased durability and overall performance of an adhered masonry veneer can be achieved when the design begins with the substrate and works to the face of the veneer. ![]() Pre-made, slip and fit patterns, more color choices, and overall quality of the products have increased, bringing big improvements from years past. Today’s adhered masonry veneers offer a wider range of aesthetics than in previous years. We will look at some of the more prevalent products commonly found in adhered masonry sections and how they individually can affect your thin veneer walls. Many of the design changes in recent times are a result of economic changes in materials, improvements based on testing, higher performance by design, and installation improvements. Here is a simple primer that includes materials we work with on a daily basis. Adhered masonry veneers are better designed and perform more efficiently when the entire wall system is considered before and during installations. Walls today offer better technology and water protection than in years past. Words: Steven Fechino, Engineering and Construction Manager, Mortar Net Solutions ![]()
