Our HVAC Duct Insulation Rock Wool is a specialized insulation material for heating, ventilation, and air conditioning systems, crafted from fine basalt fibers through precise processing. The rock wool's flexible structure fits tightly around duct surfaces, eliminating gaps that cause heat loss. It is also non-combustible and free of harmful substances, ensuring safety in enclosed spaces like ceilings and walls where ducts are installed.

Product Advantages
1.Low thermal conductivity reduces HVAC energy consumption, lowering operational costs for buildings.
2.Flexible fiber structure adapts to rectangular, circular, and irregular duct shapes, ensuring full coverage without gaps.
3.Sound absorption coefficient ≥0.65 reduces duct noise transmission by 10-15dB, improving indoor acoustic comfort.
4.A1-class fire resistance prevents flame spread through ducts, enhancing building fire safety.
5.Resists mold and bacteria growth.
FAQ
Q: How to install the HVAC Duct Insulation Rock Wool on curved ducts?
A: The flexible mat can be wrapped directly around curved ducts, with overlapping edges of 50mm and fixed with aluminum foil tape. For diameters ≤300mm, we recommend using 25-30mm thick rock wool for tight fitting.
Q: Does this product meet indoor air quality standards?
A: Yes. It is free of asbestos, formaldehyde, and volatile organic compounds (VOCs), complying with NSF 61 and GB/T 18583 standards, making it safe for residential and commercial HVAC systems.
Q: What is the service life in HVAC duct applications?
A: When protected from direct moisture, the insulation maintains stable performance for 15-20 years, which aligns with the service life of most HVAC systems. Regular visual inspections every 5 years are recommended.
