FIRE-RESISTANT VS. FIRE-RATED: DECODING MGO BOARDS’ PERFORMANCE IN REAL BUILDING CODE TESTS Understanding why A1 non-combustibility and 3-hour fire ratings are not the same thing. Many architects, contractors, and distributors use the terms fire-resistant and fire-rated interchangeably. However, in building codes and fire testing standards, these terms describe two different aspects of fire performance. A board may be non-combustible but not provide a certified fire-resistance period. Likewise, a fire-rated assembly must demonstrate its ability to withstand fire exposure for a specified period of time. In this article, we explain the difference and show how MgO boards perform in both real flame exposure and certified fire testing. Fire-Resistant vs. Fire-Rated: What's the Difference? Fire-Resistant refers to a material's ability to resist ignition, combustion, and flame spread. Fire-Rated refers to the ability of a complete system or assembly to maintain integrity for a specified period such as 1 hour, 2 hours, or 3 hours under standardized fire testing conditions. In simple terms, a material can be fire-resistant, while a wall or ceiling system built with that material can achieve a fire rating. Real Flame Exposure Test: 1200°C Torch for 9 Minutes To demonstrate the fire performance of our MgO board, we exposed the board surface to a torch flame reaching approximately 1200°C for 9 minutes. Direct flame exposure approximately 1200°C Continuous testing duration: 9 minutes No sustained combustion observed No flame spread across the board surface Board maintained structural integrity after testing A1 Classification: Understanding Non-Combustibility One of the most important fire performance indicators for building materials is reaction-to-fire classification. Our MgO board achieved an A1 classification, the highest category for non-combustible building materials. A1 classification indicates that the material contributes little or no fuel to a fire and demonstrates excellent non-combustibility characteristics. 3-Hour Fire Resistance Rating While A1 classification evaluates material combustibility, fire-resistance testing evaluates how long a building assembly can withstand fire exposure. Our tested wall system achieved up to 3 hours of fire resistance performance under standardized testing conditions. A1 Non-Combustible Material Classification Up to 3-Hour Fire Resistance Rating Suitable for fire-rated wall systems Suitable for partitions and fire doors Supports building code compliance requirements Why Building Codes Require Both Modern building regulations focus on both fire prevention and occupant protection. A material should resist ignition and flame spread, while a fire-rated assembly should maintain integrity long enough to support evacuation and emergency response. This is why both A1 non-combustibility and fire-resistance ratings play important roles in building safety. Conclusion When evaluating fire performance, it is important to understand that fire-resistant and fire-rated are not the same thing. ✔ A1 Classification = Non-Combustible Material ✔ Fire Rating = Time-Based Fire Resistance ✔ 1200°C Torch Test Demonstrates Real Flame Resistance ✔ Up to 3-Hour Fire Rating Supports Fire-Safety Design By combining non-combustibility and certified fire-resistance performance, MgO boards provide a reliable solution for fire-rated building systems.

MGO BOARDS VS. DRYWALL VS. PLYWOOD: WHICH ONE TRULY SAVES YOU MAINTENANCE COSTS IN THE LONG RUN? The cheapest board today may not be the most economical choice tomorrow. When selecting materials for walls, ceilings, partitions, or flooring systems, many project owners focus primarily on purchase price. However, the true cost of a building material is often determined by what happens after installation. Repairs, replacement, repainting, moisture damage, and fire-related risks can significantly increase maintenance expenses throughout the service life of a building. This article compares MgO Boards , drywall, and plywood from a long-term ownership perspective to help identify which material may offer better value over time. At First Glance, All Three Materials Look Similar Many building projects use MgO boards, drywall, or plywood for interior construction. While their initial appearance may seem comparable, their long-term performance can be very different. Initial Purchase Cost Is Only Part of the Story Drywall is often selected because of its low upfront cost. Plywood may offer higher strength but generally comes at a higher material cost. MgO boards can sometimes have a slightly higher purchase price than standard drywall, but evaluating materials based solely on initial cost may overlook future maintenance expenses. Common Maintenance Issue #1: Drywall Cracking Drywall remains one of the most widely used interior wall materials because of its affordability and availability. However, over time, drywall may develop visible cracks caused by building movement, joint stress, accidental impacts, or repeated renovations. Although these issues are usually repairable, they often require patching, sanding, repainting, and additional labor costs throughout the life of the building. Joint cracking Surface damage from impacts Repeated repainting requirements Ongoing maintenance expenses Common Maintenance Issue #2: Moisture-Related Plywood Problems Plywood offers good strength and versatility, making it a common choice for many construction applications. However, when exposed to excessive moisture, water intrusion, or long-term humidity fluctuations, plywood may experience dimensional changes. In severe cases, warping, swelling, surface degradation, or delamination can occur, resulting in additional repair or replacement costs. Warping and deformation Swelling caused by moisture exposure Surface deterioration Potential replacement expenses How MgO Boards Can Help Reduce Long-Term Maintenance Costs While purchase price is often the first factor considered during material selection, many project owners today focus on total ownership cost, which includes repairs, maintenance, replacement cycles, labor expenses, and service life. For projects requiring fire-rated interior systems, many contractors choose MgO board solutions because of their combination of fire performance, dimensional stability, and finishing flexibility. Non-combustible material suitable for fire-rated applications Good dimensional stability under normal indoor conditions Less susceptible to common drywall cracking issues Suitable for partitions, ceilings, flooring substrates, and decorative systems May help reduce repair frequency over the service life of the building Compatible with painting, laminating, and decorative finishes MgO Board Solutions for Different Applications Different projects require different specifications. Whether for partition walls, flooring substrates, or decorative systems, selecting the appropriate MgO board can help improve long-term building performance.

These defects not only affect the appearance and flatness of the building wall, but also bring potential safety hazards and increase frequent maintenance pressure for building operation.   Completely different from traditional chloride-containing panels, OUSHIBAO’s pure chloride-free formula fundamentally eliminates the aging and damage risks caused by chloride ion erosion. With optimized molecular structure and stable material composition, the board maintains stable physical and chemical properties in long-term service scenarios, without efflorescence, salt precipitation or structural loosening. It can permanently maintain consistent fireproof performance, flatness and structural strength throughout the entire building service cycle.   In terms of environmental aging resistance, OUSHIBAO chloride-free MGO fireproof board has outstanding adaptability to long-term temperature changes, humidity circulation and air oxidation. It will not warp, crack or deform due to seasonal climate changes or long-term indoor and outdoor environmental erosion. The stable anti-aging performance effectively avoids performance degradation caused by long-term environmental exposure, realizing true long-term zero-maintenance advantages.   The excellent durability of OUSHIBAO chloride-free MGO fireproof board greatly extends the service life of building fireproof structures, effectively reducing the comprehensive construction and maintenance costs of projects. While meeting international A1 fire resistance and environmental protection standards, the product solves the industry pain point of short service life and unstable later performance of traditional fireproof boards, creating higher long-term economic value for construction projects.   Adhering to the design concept of long-term reliable quality, OUSHIBAO always takes product durability and stability as the core of product iteration. The company will continue to optimize material aging resistance technology, further improve the long-term service performance of products, and provide global customers with more durable, safer and more cost-effective chloride-free MGO fireproof building material solutions.
