Our 80kg/m³ curtain wall firestop rock wool board is specially engineered for sealing joints and gaps in glass curtain wall systems. Designed with excellent compressibility and workability, it effectively fills gaps between curtain walls and floors, providing superior protection against flame and smoke spread.
Manufactured from high-quality rock wool with long, elastic fibers, this board conforms perfectly to irregular gaps and curtain wall framing components. It serves as an ideal firestopping solution for cost-sensitive projects requiring reliable performance.
| Parameter Product | FH80 |
|---|---|
| Density (kg/m³) | 80 |
| Combustibility | Class A1 non-combustible |
| Melting Point (°C) | ≥1000 |
| Fire Rating after Compress (h, thickness≥100mm) | ≥2 |
| Thermal Conductivity (W/m·K, 25°C) | ≤0.040 |
| Acidity Coefficient | ≥2.0 |
| Hydrophobic Rate (%) | ≥99.0 |
Excellent compressibility and resilience ensure tight filling of gaps between curtain walls and floors, comprehensively preventing flame and smoke spread.
Lower density makes boards lighter for easier handling, cutting, and stuffing, accelerating installation processes.
Rock wool is Class A non-combustible material with no burning, no flame, and no toxic smoke spread during fire events.
High acidity coefficient ensures corrosion and aging resistance—no powdering, no shrinkage—maintaining seal performance over time.
