Feature Advantages
Class A1 Non-Combustible - Maximum Building Safety

Meets Class A1 non-combustible material standard: does not burn, contribute to fire, or propagate flames. With a melting point above 1000°C, it provides the most reliable fire barrier for buildings.

No Toxic Fumes During Fire - Reducing Suffocation Risk

100% inorganic mineral fibers emit no toxic gases or dense smoke during a fire, buying crucial time for evacuation and maximizing life safety.

Stable Physical-Chemical Properties - Long-Term Fire Protection

High acidity coefficient ensures resistance to corrosion, humidity, and chemical exposure—fire performance never degrades over time, providing lasting protection.

Permanent Dimensional Stability - No Gaps for Flames

Excellent thermal stability means no shrinkage, deformation, or cracking under high temperatures, ensuring tight panel joints and effectively blocking flame penetration paths.
