Class A Fireproof Rock Wool for Smoke Exhaust System – Ventilation Duct / Duct Wrap
Product Overview
With unique production formula, our Class A fireproof rock wool is specially engineered for fireproof wrapping and insulation of ventilation ducts, smoke exhaust ducts, and HVAC ducts. Meeting the Class A1 non-combustible material standard, it does not burn or emit toxic fumes during fire, effectively delaying flame spread along ducts and ensuring smoke exhaust systems remain operational. With excellent thermal insulation, it reduces duct heat loss and prevents condensation. Ideal for high-rise buildings, commercial complexes, and industrial plants.
Applications
Fireproof wrapping for smoke exhaust ducts in high-rise buildings
Ventilation ducts in commercial complexes, underground spaces
Smoke control systems, positive pressure supply ducts

Key Features
Class A Non-Combustible - Core Duct Fire Protection: Meets Class A1 non-combustible standard, with no burning, flame spread, or toxic fumes, ensuring smoke exhaust system functionality.
High-Temperature Stability - No Shrinkage Under Fire: Rock wool melting point >1000°C, with no shrinkage or melting at high temperatures, maintaining fire wrap integrity.
Thermal Insulation - Condensation Prevention: Low thermal conductivity reduces duct heat loss and prevents condensation, extending duct service life.
Easy Installation - Fits All Duct Types: Can be cut on-site for tight fit with rectangular and circular ducts, with simple installation.
Durable - Long-Term Performance: High acidity coefficient ensures corrosion and aging resistance, matching building lifespan.
