PIR foam Aluminium Foil Duct Panel

PIR foam Aluminium Foil Duct Panel represent a high-performance core solution for contemporary HVAC systems. Featuring an integrated sandwich structure with aluminium foil facings and a rigid PIR foam core, they deliver superior performance compared to conventional galvanised steel ducts that demand on-site insulation treatment. Suited for an extensive variety of projects, these duct panels are commonly specified for hotels, office complexes, airports, hospitals, as well as other commercial and public facilities.

Fire protection, durability and operation and maintenance costs of PIR foam Aluminium Foil Duct Panel

Fire Safety

PIR foam core: Class B1 flame retardant; aluminium foil surface: A1 non-combustible. Low smoke output and no dripping while burning. Complies with BS 476 and EN 13501, ideal for high fire-risk sites: data centres, subways and hospitals.

Long Service Life

Strong corrosion resistance. 95% strength retained after 720 hours acid/alkali immersion; no rust or pulverisation. Designed service life: 20 years. Galvanized steel ducts rust easily (5–8 years lifespan); phenolic ducts crack within 3–5 years.

Lower O&M Costs

Built-in moisture and corrosion resistance; no yearly rust removal and repainting required. Annual maintenance cost equals only 30% of traditional ducts. Low air leakage lessens load on main units, cutting fan loss and maintenance frequency. Total life-cycle costs are reduced by 30%–40%.
