Rigid PU Foam Pre-insulated Duct
More than just regular duct materials, rigid PU foam pre-insulated duct is an all-in-one HVAC solution that drastically cuts your on-site labor, shortens project schedules and lowers long-term building operation costs, beating traditional GI duct systems in every core construction aspect.
Product Core Structure
This integrated sandwich panel features a high-density closed-cell rigid PU foam core firmly bonded with double-sided aluminum foil facings, combining insulation, air barrier and duct structure into a single finished board ready for direct fabrication.
Standard size: 4000*1200*20mm
Thermal Conductivity: 0.020w/m.k
Key construction advantages contractors care about of Rigid PU Foam Pre-insulated Duct
Huge labor & time savings:
70% lighter than galvanized iron ducts, no separate on-site insulation wrapping required; duct fabrication and installation speed rises by 40%–60%, helping you finish HVAC handover ahead of schedule and cut labor expenses.
Zero condensation & fewer after-sales complaints:
Closed-cell PU foam with ultra-low water absorption stops condensation, mold and rust issues that frequently trigger client complaints on GI duct projects, reducing your rework and maintenance workload.
Superior energy performance for easier project approval:
Ultra-low thermal conductivity minimizes air temperature loss, slashing building air conditioning energy consumption by 20%–30%; it easily meets green building and energy-efficiency codes to simplify your tender and acceptance procedures.
Simplified joint sealing with complete matching system:
Supporting full sets of matched aluminum/PVC flanges, special sealant and hanging hardware from the UNTDuct PU System, all accessories fit panels perfectly to guarantee airtight ducts without leakage rework.
Wide applicable project coverage:
It works for commercial malls, office towers, hotels, hospitals, cleanrooms, cold storage and coastal humid buildings, covering nearly all your common HVAC tender projects.
Lower whole-life cycle cost for your clients:
With a service lifespan of 20–50 years and minimal maintenance needs, this duct offers obvious long-term value for building owners, making your quotation more competitive during bidding.
