Architects & Specifiers
Performance, Compliance, and Design Flexibility
Architects and specifiers need materials that meet code, enhance durability, and simplify the design process. Cemrock magnesium oxide (MgO) boards are tested and certified for fire, moisture, and air quality performance, making them a superior alternative to OSB, plywood, cement board, and gypsum-based systems.
Designed for interior and exterior applications, Cemrock integrates seamlessly into UL-rated wall assemblies, partition systems, and sustainable building designs.
What Cemrock Replaces
Cemrock eliminates the need for multiple layers of traditional materials, simplifying wall and floor assemblies while exceeding performance standards.
Cemrock MgO Board Can Replace:
• OSB/Plywood – Cemrock is moisture-resistant, mold-proof, and non-combustible, unlike wood-based sheathing.
• Cement Board – Cemrock is lighter, stronger, and doesn’t crack under stress.
• Gypsum-Based Fire-Rated Boards – Cemrock is inherently fire-resistant with UL-listed assemblies.
• Moisture-Resistant Drywall – Cemrock eliminates swelling, softening, and mold risks.
Our boards deliver structural integrity, fire resistance, and water protection—without multiple material layers.
UL Certifications & Fire Ratings
Cemrock is UL GreenGuard Gold Certified and tested for use in UL-rated wall and floor assemblies. It meets the highest standards for fire resistance, air quality, and sustainability.
Key Certifications & Compliance
1. UL Fire-Rated Assemblies – Cemrock meets ASTM E136, making it a non-combustible building material.
2. UL 263 & ASTM E119 Tested – Approved for use in 1-hour and 2-hour fire-rated assemblies.
3. UL GreenGuard Gold – Certified for low chemical emissions and indoor air quality compliance.
4. ASTM C1186 – Meets performance standards for weather resistance, durability, and impact strength.
Cemrock ensures compliance with international building codes, simplifying approvals and reducing liability risks.
Where Cemrock Fits in Architectural Design
Cemrock is designed for high-performance building systems where fire safety, moisture resistance, and structural durability are essential.
Applications for Cemrock:
• Fire-Rated Partitions – Cemrock can be used in non-load-bearing and structural wall assemblies.
• Sheathing for Exterior Walls – Superior moisture and wind resistance for rainscreen systems.
• Interior Wall & Ceiling Panels – Fireproof and mold-resistant for commercial and residential spaces.
• Flooring & Substrates – High-impact and water-resistant, ideal for wet areas, mezzanines, and underlayments.
• Modular & Prefabricated Systems – Ideal for factory-built panels and unitized construction.
Whether designing a commercial high-rise, modular housing, or a sustainable build, Cemrock adapts to your architectural needs.
Why Cemrock Matters for Architects
Specifying Cemrock means choosing a proven, code-compliant material that enhances building longevity and sustainability.
Key Benefits
1. Streamlines Design & Compliance – Fewer materials, fewer layers, easier approvals.
2. Improves Building Resilience – Fireproof, mold-proof, and impact-resistant.
3. Meets Sustainability Goals – GreenGuard Gold certified, non-toxic, and long-lasting.
4. Enhances Acoustic Performance – Contributes to soundproofing and STC-rated partitions.
5. Speeds Up Construction – One board replaces multiple materials, reducing installation time.
