New Study Proves PermaBase® BRAND Cement Board Saves Time and Money
OnBoard Newsletter | November 2018
If your construction team could install something 35 percent faster and save 6 percent in costs, would you specify it? That’s exactly what PermaBase® BRAND Cement Board can do, according to a new study conducted by Home Innovation Research LabTM using PermaBase® as a substrate in exterior wall systems with a polymer-modified veneer mortar.
“Time is money, and using PermaBase as a substrate in exterior wall systems with modified mortar can reduce construction time, reduce total installed costs and increase system performance for exterior applications,” says Tony Fuller, National Gypsum product manager for PermaBase. “Given the construction industry’s shortage of skilled labor, evolving building envelope requirements and related construction costs, this is good news for architects, builders, general contractors and their clients.”
Conducted on behalf of National Gypsum and co-sponsors Laticrete and Eldorado Stone, the study compared the installation of two adhered masonry veneer systems – PermaBase Cement Board with the modified veneer mortar versus a traditional lath-and-cement mortar base. Stacked stone veneer was installed on each of two identical facades of Home Innovation’s test house during this study.
Engineered System You Can Count On
PermaBase is a component of an engineered system that saves time, labor and takes variability out of the assembly. With this substrate, you can eliminate application errors, labor shortages and project scheduling issues. Extremely durable, PermaBase is excellent for a variety of exterior applications, including stucco, stone and thin brick. This code-compliant material is a single substrate compatible with multiple finishes, is appropriate for all climates and includes easy integration with continuous insulation. Moisture resistant, this specially fabricated cement board helps inhibit mold growth with the highest score on mold tests (ASTM D3273 and ASTM G21) and it achieves the industry’s lowest water-absorption rating (ASTM C473). Built for the long run, it stays intact when exposed to water; it will not rot, disintegrate or swell. It also meets UL classifications for one- and two-hour fire-rated assemblies. PermaBase offers a superior 15-year exterior warranty.
Versatile to Accommodate All Your Projects
With four types of PermaBase to choose from, you’ll find a match for most any project. Lightweight and easy to install, all PermaBase Cement Boards are GREENGUARD Gold Certified for low chemical emissions, which can contribute to healthier indoor environments.
The PermaBase product family:
° PermaBase Cement Board – our original, it sets the industry standard. Available in 1⁄2” and 5⁄8” thicknesses and complies with ASTM C1325.
° PermaBase PLUS® Cement Board – weighs 25 percent less than standard Cement Board. Available in 7⁄16” thickness.
° PermaBase UltraBacker® Cement Board – provides excellent rigidity for floor and countertop applications. Available in 1⁄4” thickness.
° PermaBase Flex® Cement Board – works well around archways, columns and stairwells. Available in 1⁄2” thickness.
Meets Stringent Code Standards
PermaBase is ideal for both Cement Board Stucco Systems (CBSS) and Cement Board Masonry Veneer (CBMV) Wall Systems. The American Society for Testing and Materials (ASTM) and International Building Code (IBC) accept both CBSS and CBMV as solid exterior wall options that meet stringent commercial code standards as documented in UL Evaluation Report 22158. Ask your Construction Design Manager (CDM) and he or she can provide required documentation. Your CDM is also available to explain the system to a code official involved with your project, if you would like additional assistance.

"One of the most popular AIA Lunch ‘N Learn Programs National Gypsum offers is our “Cement Board and Exterior Finish Systems” Presentation. As you have read, there are several advantages to specifying Cement Board Masonry Veneer and Cement Board Stucco. The one that sticks out to me is the simplicity of installing it. Established manufacturers collaborated to develop a system that works. Simple, fast, code approved and less expensive."
