PIRALU Pre-insulated duct panel

PIRALU Pre-insulated duct panel is a premium HVAC duct solution with a rigid PIR foam core and double-sided aluminum foil facings. It delivers exceptional thermal insulation (thermal conductivity ≤0.02 W/m·K), outstanding fire resistance (Euroclass B-s1, d0), and lightweight rigidity.

Featuring airtight joints, anti-microbial surface, and easy fabrication, it minimizes energy loss, air leakage, and installation time. Ideal for commercial, industrial, and residential HVAC systems, it's a green, cost-effective alternative to traditional galvanized iron ducts.

Installation and Construction of PIRALU Pre-insulated duct panel

Convenient and Efficient
Factory prefabrication, on-site cutting and splicing, without the need for secondary insulation. With dedicated accessories, installation efficiency is increased by 50%-60%, shortening the construction period and reducing labor costs.

Excellent Sealing Performance
Special sealing glue and connection techniques result in a leakage rate of ≤1%, far below the national standard. Reduces the loss of cold or hot air, improves system energy efficiency, and ensures stable indoor temperature and humidity.

Space Optimization
Integrated design with a thinner thickness saves ceiling space, facilitates complex pipeline layout, and is suitable for high-rise buildings, basements, machine rooms, and other confined spaces.

Durability and Maintenance of PIRALU Pre-insulated duct panel

Corrosion and moisture resistance
Aluminum foil is resistant to acids and alkalis, anti-aging, has zero water absorption rate, and eliminates the risks of damp corrosion, rusting, and air leakage. The PIR closed-cell structure prevents condensation, inhibits mold growth, and has antibacterial properties, making it suitable for high-humidity and clean environments (hospitals, food factories).

Long lifespan and low maintenance
The normal service life exceeds 20 years. There is no rusting or detachment of the insulation layer. The maintenance cost is 70% lower than that of traditional ducts, and the long-term economic benefits are significant.

Green and Environmentally Friendly
Free of Freon (CFC/HCFC), low VOC, pollution-free during production and use. Energy-saving and consumption reduction, carbon emission reduction, suitable for green buildings and LEED certification.
