In the ever-evolving world of commercial low-slope roofing, DEXcell® Roof Boards stand out as a beacon of innovation and reliability. DEXcell continues to set the standard for quality, availability and support in the commercial roofing industry. Here’s why DEXcell Roof Boards, provided by National Gypsum Company, should be the go-to-choice for your roofing system needs.

Nationwide Access

One of the key strengths of DEXcell Roof Boards is their nationwide availability. With 11 manufacturing plants and five additional warehouses spread across the country, DEXcell ensures you have access to their high-quality products no matter where your project is located. This extensive coverage is further supported by a nationwide network of independent representative firms, making it easier than ever to source the right roof board for your needs.

DEXcell offers a single source for four distinct roof board product options, suitable for both coverboards and thermal barriers. These products are integral components in every leading commercial low-slope roofing system, ensuring you have high-quality materials at your disposal. The breadth of system partners providing nationwide availability further underscores DEXcell’s commitment to availability.

With partnerships spanning nearly every major commercial roofing manufacturer, DEXcell products are trusted components in systems from industry leaders like GAF, Carlisle, Johns Manville, Elevate, and more. This nationwide network of system partners not only reinforces DEXcell’s reputation for quality and compatibility but also ensures seamless integration into virtually any low-slope roofing specification.

Exceptional Quality

Quality is at the heart of DEXcell Roof Boards. With a proven track record of performance, these roof boards meet the most stringent third-party product and testing standards, including FM Global standards, UL fire ratings and ASTM standards. DEXcell is also included in IBC, FBC, Miami-Dade and various other building codes.

DEXcell’s Sealed Surface Technology is a specialized feature integrated into its DEXcell® Glass Mat, DEXcell FA® Glass Mat and DEXcell FA VSH® Glass Mat roof boards, designed to enhance both installation efficiency and system performance. The technology involves precoated facers—a treatment applied to the surface of the roof boards. These facers are coated on the front, back and sides of the gypsum core, which is also mold- and moisture-resistant.

DEXcell’s commitment to quality is backed by extensive research and development, as well as industry-leading expertise in fiberglass mat technology. This dedication to innovation ensures DEXcell roof board products not only meet but exceed industry standards, providing you with a product you can trust.

Technical Resources and 1-800-NATIONAL Support
DEXcell’s commitment to support begins with a robust suite of technical resources designed to guide professionals from specification through installation. The DEXcell Technical Guide offers in-depth product and application insights, while the award-winning National Gypsum Customer Service Center is staffed with experts ready to assist.

For more personalized support, the 1-800-NATIONAL Construction Services team is available to answer project-specific questions, provide code compliance guidance, and help troubleshoot installation challenges. This team, backed by over 150 years of combined experience in building materials, ensures that contractors, consultants, and distributors always have a knowledgeable partner on call.

Architectural Support from Construction Design Managers
Architects benefit from direct access to National Gypsum’s Construction Design Managers (CDMs)—regionally based experts who provide technical consultation and specification support. CDMs are trusted advisors who help architects navigate complex code requirements, select appropriate assemblies, and integrate DEXcell products into high-performance roofing systems.

Whether it’s reviewing submittals, assisting with LEED documentation, or presenting AIA-approved education sessions, CDMs serve as an extension of the design team, ensuring that every detail aligns with project goals and performance standards.

Continuing Education for the Design Community
National Gypsum offers a range of AIA-approved continuing education courses tailored to roofing professionals and design teams. These include “Advantages of Using Coverboards on Low-Slope Roofing Assemblies,” which explores the performance benefits and installation considerations of coverboards, and “High Performance Gypsum: Protection Against Mold, Moisture and Exposure,” which highlights moisture mitigation strategies in roofing systems.

For those newer to gypsum products, “Gypsum Fundamentals: Design with Confidence” provides a solid foundation. All courses are eligible for HSW credits and are available both online and in-person, making it easy for architects and specifiers to stay current on best practices while earning professional development hours.

In conclusion, DEXcell Roof Boards are engineered to strengthen every commercial roofing system. With nationwide access, exceptional quality, and unparalleled support, DEXcell is the ideal choice for your commercial roofing needs.
