When it comes to fire door construction, the core material is the backbone of safety, durability, and performance. Magnesium Oxide (MGO) board has emerged as a revolutionary choice for fire door cores, redefining industry standards with its exceptional properties and versatile advantages.
Unmatched Fire Resistance: Your First Line of Defense
At the heart of MGO board's appeal as a fire door core is its Class A1 non-combustible rating , the highest fire safety classification for building materials. Unlike traditional options like gypsum board, which begins to carbonize at 200°C , MGO board maintains structural integrity even when exposed to temperatures up to 1200°C This extraordinary heat resistance translates to fire protection durations of up to 4 hours , providing critical extra time for evacuation and emergency response in commercial, industrial, and residential settings. Most importantly, it releases zero toxic fumes during combustion , eliminating a major hidden hazard of conventional materials that can compromise occupant safety.
Beyond Fire Safety: Comprehensive Performance Advantages
MGO board doesn't just excel at fire protection—it delivers all-around performance that enhances the entire lifecycle of fire doors:
● Moisture & Durability Mastery: Unlike gypsum, which decomposes and loses strength when exposed to water , MGO board boasts excellent water and moisture resistance. It can withstand prolonged exposure (even 100 days of soaking) and retain its physical properties after drying , making it ideal for high-humidity environments like kitchens, bathrooms, and basements. Advanced formulations also eliminate the "sweating" issue associated with inferior magnesium boards , ensuring long-term structural stability without corrosion or warping.
● Strength & Structural Reliability: Reinforced with cloth-like glass fiber mesh , MGO board achieves impressive mechanical performance despite its lightweight nature (density of 0.9–1.3 g/cm³) . It offers superior impact resistance (≥4.5 kJ) and bending strength (≥20 MPa) compared to calcium silicate and gypsum boards , preventing damage from daily use and ensuring the fire door maintains its integrity over time. Its service life for indoor applications can reach at least 25 years .
● Eco-Friendly & Healthy: Crafted from abundant, naturally occurring magnesium oxide , MGO board features a sustainable production process with a reduced CO₂ footprint . It contains no harmful substances such as asbestos, formaldehyde, or benzene , promoting healthy indoor air quality and complying with strict environmental regulations worldwide.
● Installation & Versatility: MGO board simplifies fire door manufacturing with its ease of processing. It can be cut with standard tools like wallpaper cutters or saw blades, and fastened with pneumatic nails or screws —saving time and labor costs compared to rigid alternatives. Available in thicknesses from 3mm to 50mm , it fits various door designs and can be paired with decorative materials like veneers, PVC, or aluminum sheets for seamless integration into any architectural style.
Why MGO Board Outperforms Traditional Core Materials
When compared to conventional fire door core materials, MGO board stands out across every critical metric:
Feature | MGO Board | Traditional Materials (Gypsum/Calcium Silicate) |
Fire Resistance | Class A1, up to 4hrs protection | Class B (gypsum) or A1 but heavier |
Moisture Resistance | Excellent, no decomposition | Poor (gypsum) or limited (30-day soak max) |
Weight & Strength | Lightweight (0.9–1.3g/cm³) with high impact resistance | Heavier with lower flexibility |
Health & Safety | Zero toxic fumes, asbestos-free | Potential toxin release or asbestos content |
Installation Ease | Easy to cut/fasten with standard tools | Requires specialized tools |
Trusted by Professionals Worldwide
