PIR HVAC Air Ducting
PIR HVAC Air Ducting constitute a high-performance and eco-conscious solution for modern HVAC systems. Designed as an integrated sandwich composite with aluminum foil facings and a rigid PIR foam core, they surpass conventional galvanized steel ducts that require separate on-site insulation work.
Thanks to low thermal conductivity and optimised material composition, these duct panels help cut energy consumption throughout the system lifecycle. Free from harmful blowing agents and boasting outstanding thermal stability, they align with sustainable building standards. Widely specified for hotels, office buildings, airports, hospitals and a broad range of commercial and public green building projects.

Core Benefits of PIR HVAC Air Ducting That Benefit Your Contracting Business

✅ Greatly Save Construction Time & Labor Expense Around 70% lighter than galvanized steel. No on-site duct fabrication and insulation wrapping. Installation efficiency increases 40%–60%, helping you handle more projects without extra labor overtime.
✅ Reduce Rework & After-sales Headaches Low water-absorption closed-cell PIR foam avoids condensation, mold and rust issues typical of insulated metal ducts, lowering repair callbacks.
✅ Energy-saving Edge to Secure Bids Ultra-low thermal conductivity cuts AC energy use by 20%–30% and meets green building regulations, forming a key advantage in tender competitions.
✅ Full UNTDuct Supporting System for Tight Assembly Matching aluminum/PVC flanges, sealant, hangers and professional tools guarantee airtight joints and avoid air leakage rework.
✅ Wide Project Adaptability Fit for offices, malls, hotels, hospitals, food cleanrooms, cold storage and humid coastal constructions, covering most commercial HVAC projects.
✅ Long-term Economic Value for End Users 20–50 years service life with little maintenance, lowering long-run building operating costs and improving your quotation appeal.
We provide free technician training, standard construction drawings, on-site technical guidance and ongoing consultation to help your team proficiently process and fabricate ducts.
