Flame Retardant Aluminum Foil Faced Fireproof Rock Wool Duct Wrap

Our flame-retardant aluminum foil-faced fireproof rock wool combines a Class A fireproof rock wool slab with a high-strength flame-retardant aluminum foil, engineered for fire protection, moisture control, and cleanliness in smoke exhausting and ventilation ducts, HVAC ducts, and cleanroom ducts.

The foil facing provides superior moisture resistance, effectively blocking vapor penetration to prevent condensation, while offering radiant heat reflection to reduce energy loss. With a smooth, dense surface that is easy to clean and dust-resistant, it is ideal for cleanrooms, hospitals, and laboratories with strict hygiene requirements.

• Ventilation and smoke exhaust ducts in cleanrooms, electronics factories
• Cleanroom ducts in hospital operating rooms, ICUs
• Exhaust systems in laboratories, pharmaceutical plants
• Ventilation ducts in food processing plants, cold storage
• Projects requiring moisture resistance and cleanliness

• Flame-Retardant Aluminum Foil – Dual Fire Protection
  The foil is flame-retardant grade, combined with Class A non-combustible rock wool for excellent overall fire performance with no flame spread.
• Moisture & Mold Resistance – Condensation Prevention
  The foil layer has near-zero vapor permeability, effectively blocking moisture to prevent condensation and mold.
• Radiant Heat Reflection – Energy Savings
  The aluminum surface reflects radiant heat, reducing thermal loss in ducts and lowering HVAC energy consumption.
• Clean & Easy Maintenance – Hygienic
  Smooth, dense foil surface resists dust accumulation and is easy to clean, meeting cleanroom and medical hygiene standards.
• Easy Installation – Aesthetic Finish
  Wrap directly around ducts with the aluminum surface requiring no additional finishing, leaving a neat appearance.
