Product Description
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
  • Industrial dust extraction ducts, smoke exhaust ducts
  • HVAC duct insulation and fire protection
  • Smoke control systems, positive pressure supply ducts
