What architects should know about manufactured stone veneer

From both an aesthetic and performance standpoint, manufactured stone offers a range of opportunity for both residential and commercial architects. Manufactured stone veneer’s versatility ensures flexibility and freedom in design alongside long-term durability for the client.

How Manufactured Stone Veneer Benefits Architects

Among manufactured stone’s advantages are a handful that ensure architectural freedom.

• Authenticity without limitations: Manufactured stone veneer offers the look of natural stone but without some of the drawbacks that might hinder design freedom. MSV masters are made using natural stone, and new technologies allow for replication of fine details. At the same time, MSV is lighter in weight, isn’t limited by locality, and typically costs less than natural stone.
• Diversity of styles and colors: Because it’s manmade, the options for profiles, textures, and colors of manufactured stone are vast. Exotic or unique looks are not limited to far-flung locales, so nearly any aesthetic vision is possible. At the same time, MSV doesn’t have to be purely natural in feel—it is also available in many modern, contemporary profiles and monochromatic color schemes.
• Consistency: The look and availability of natural stone cannot be controlled, which means there can be no promise of consistency or availability. With manufactured stone, on the other hand, repairs, replacements, or additions can typically be made possible because the materials do not rely on nature’s availability. This also means less culling and sorting to find flaw-free looks that coordinate on the wall.
• Application versatility: Because manufactured stone veneer is lighter in weight than natural stone, it can be used in a broader array of applications that stone or brick may be too heavy for. It’s also suitable for horizontal and vertical applications as well as for interior and exterior projects.

What Should Architects Keep in Mind When Specifying Manufactured Stone Veneer?

Manufactured stone veneer’s makeup and application mean there are a few factors that architects should consider in plans and specifications.

• Weatherization: As outlined in CMHA’s Manufactured Stone Veneer Installation Guide, rainscreens that create a capillary break/air space between the cladding and the water resistive barrier can be effectively incorporated into adhered manufactured stone veneer applications. Some local codes require the use of a rainscreen. Refer to the manufacturer’s recommendation for rainscreen/drainage system applications, and drainage space size requirements may vary from jurisdiction to jurisdiction.
• Wall ties and footings: Because it’s lighter in weight than natural stone, MSV typically doesn’t require wall ties and footings. Manufactured stone also requires fewer structural modifications for remodeling applications.
• Height considerations: Depending on the structural material, installation heights may be limited for some manufactured stone. Check with the manufacturer and local building code requirements for more information.
• Fireplace applications: Most manufactured stone veneer can be used for fireplace surrounds, but consideration should be given for avoiding exposure to direct flame. For instance, MSV should not be used as returns into a firebox of a fireplace.
