The Science of Time: Class A1 Fire-Rated Gypsum Systems for High-Stakes Architecture
In modern structural engineering, fire safety is measured in minutes. Our Class A1 Non-Combustible Gypsum Board is engineered to serve as a critical thermal shield, delaying the transfer of heat through partitions and ceilings. By integrating high-purity calcium sulfate dihydrate with advanced fiberglass reinforcement, we provide a passive fire protection solution that prioritizes occupant safety and structural integrity during localized thermal events.
The Endothermic Defense Mechanism Beyond simple insulation, our boards utilize a chemical fire-suppression process. The gypsum core contains approximately 21% chemically combined water. When exposed to intense heat, this water is released as steam, creating a thermal barrier that maintains the board's temperature at 100°C until the crystallization water is exhausted. This "calcination" process is what grants our 12mm and 15mm systems their certified 60 to 120-minute ratings.
Engineering Advantages & Reliability
Structural Integrity (Type X Core): Enhanced with long-strand glass fibers to prevent shrinkage and cracking under extreme temperature gradients.
Zero-Smoke Toxicity: Composed of high-purity materials that release only water vapor when heated, ensuring clear escape routes and breathable air for occupants.
Superior Acoustic Decoupling: The high-density core configuration offers a naturally high STC (Sound Transmission Class) rating, ideal for hospital and hotel partitions.
Dimensionally Stable: Minimal expansion and contraction rates ensure that fire-rated seals and joints remain intact over years of building settlement.
Precision Edge Milling: Available in tapered and square edges to facilitate seamless finishing for high-end aesthetic requirements.

Global Project Reference: Nexus International Hospital
Project Scope: The expansion of a 500-bed multi-specialty facility requiring 90-minute fire-rated separation for oxygen storage rooms and emergency corridors.
Our Contribution: We supplied over 120,000 m² of 15mm Reinforced Fire-Rated Board. Our technical team worked directly with the MEP consultants to design a staggered double-layer system that met the 120-minute local fire department requirement while achieving an STC rating of 52dB for patient privacy.
The Outcome: The project passed third-party thermal imaging tests and smoke-leakage inspections on the first attempt, saving the contractor weeks in the certification phase.
Primary Applications
Critical Infrastructure: Data centers, electrical substations, and telecommunication hubs.
Commercial Life-Safety Zones: High-rise elevator shafts, fire-escape stairwells, and service ducts.
Healthcare & Education: Surgery suites, laboratories, and school corridors where evacuation times are vital.
Industrial Compartmentation: Warehouse separation walls and hazardous material storage areas.
Logistics & Protection
We understand that board integrity is as important as its fire rating. All exports are packed using moisture-resistant PE-wrapping on reinforced wooden pallets with edge protectors. Every shipment includes a Batch Certification Report, ensuring full traceability from the raw gypsum mine to your construction site.
Frequently Asked Questions
Q: How do I distinguish between your fire-rated and moisture-rated boards? A: For safety and easy inspection, our fire-rated boards feature a pink or red face paper. This allows architects and fire marshals to verify correct installation at a glance.
Q: Can these boards be used in exterior applications? A: These are designed for interior use. For external soffits or areas exposed to direct weathering, we recommend our specialized cement-based or glass-mat sheathing boards.
Q: Does the board lose its fire rating if it is cut or drilled? A: The fire resistance is inherent to the core material. However, penetrations for cables or pipes must be sealed with approved intumescent fire-stop sealants to maintain the system's overall rating.
