PIR Air Ducting
The UNTDuct PIR Air Ducting represents an elite solution for high-efficiency ventilation and HVAC systems.
Constructed with a rigid polyisocyanurate (PIR) foam core sandwiched between double-sided aluminum foil facings, the panel delivers remarkable thermal resistance. It efficiently inhibits heat transfer and stabilizes air temperatures inside ductwork.
Beyond superior thermal performance, the panel features outstanding durability. Engineered to resist frequent operational loads and various environmental conditions, it sustains stable, reliable service over an extended service life.
Its innovative structure reshapes HVAC ducting solutions. The integrated insulation barrier drastically cuts energy loss. Less energy dissipation optimizes overall HVAC operational efficiency, bringing tangible cost savings and lowering carbon emissions.
All in all, the UNTDuctPIR Air Ducting is an ideal choice for contemporary ventilation and HVAC projects, balancing premium thermal performance, robust durability and outstanding energy-saving advantages.
Why Choose PIR Air Ducting?
Thermal Insulation, Low Smoke Emission and Low Toxicity
PI foam exhibits inherent flame retardancy for enhanced fire safety. Its Limiting Oxygen Index (LOI) is typically higher than 34%, significantly surpassing the standard requirements for most flame-retardant materials.
Excellent Acoustic and Thermal Insulation Performance
With an open-cell structure featuring an open-cell fraction of up to 99%, PI foam achieves exceptional sound absorption. It attains a Noise Reduction Coefficient (NRC) of maximum 0.54 within the frequency range of 125–4000 Hz, efficiently attenuating airflow noise and mechanical operating noise in HVAC installations. Its thermal conductivity is lower than 0.022 W/(m·K), enabling reliable thermal insulation at low areal weight.
Ultra-Low Outgassing and Chemical Stability
Volatile substances released by materials under vacuum may lead to contamination of precision apparatus. Thanks to its ultra-low outgassing property, PI foam is widely utilised in aerospace applications and semiconductor cleanroom environments. The material also offers resistance against weak acid, weak alkali and common oils such as 93# gasoline, demonstrating excellent chemical inertness.
How does PIR Air Ducting perform in terms of energy efficiency?
1.This PIR Air Ducting has excellent thermal insulation performance, effectively blocking heat transfer and minimizing cold/heat loss during air delivery.
2. Its fully sealed structure ensures superior airtightness, greatly reducing air leakage and avoiding unnecessary energy waste.
3. Stable insulation effect lowers the operating load of air conditioning and ventilation equipment, helping cut down long-term power consumption remarkably.
4. It maintains consistent indoor temperature steadily, optimizes overall HVAC operation efficiency, and brings prominent energy-saving benefits for projects.
5. Compared with traditional insulated duct solutions, the PIR Air Ducting achieves higher energy utilization rate and saves more operational costs year-round.
