PIR foam Aluminium Foil Duct Boards

UNTDuct PIR foam Aluminium Foil Duct Boards are a primary high-performance solution utilised within modern HVAC systems. Manufactured as an integral sandwich assembly clad with aluminium foil facings and incorporating a rigid PIR foam core, they exhibit better performance than standard galvanised steel ducts which require insulation installation on site. Applicable to diverse engineering projects, such duct panels are frequently selected for hotels, office buildings, airports, hospitals and additional commercial and public buildings.

Building Structural Loads of PIR foam Aluminium Foil Duct Boards

Measured weight data: PIP sheet metal finished ducts weigh 5–8 kg per square meter; traditional galvanized iron sheets + outer insulation layer ducts weigh 18–22 kg per square meter. The weight of PIP per unit area is only 1/3 of that of metal ducts.

Quantification of construction costs: For a large shopping mall with a 10,000 square meter ventilation network, the total load of metal ducts is approximately 190 tons, while PIP weighs only 65 tons. The design institute needs to thicken the main beams of the ceiling and increase the density of the suspension rods to support the metal ducts. The cost of structural reinforcement increases by 12–18 yuan per square meter; using PIP can eliminate the reinforcement process, and a project of 10,000 square meters directly saves 12–18 ten thousand yuan in construction costs.

Long-term structural wear and tear: The self-weight of metal ducts constantly pulls the ceiling joists, causing ceiling deformation and suspension rod corrosion after about 8 years; PIP has a smaller load pressure, and the service life of the ceiling structure is extended by more than 10 years, reducing the cost of building renovation and repair.
