Polyurethane PID Panels

Polyurethane PID Panels is a modern, pre-insulated ductwork system used for heating, ventilation, and air conditioning. It's designed as a high-performance alternative to traditional metal ducts, integrating structure and insulation into a single, lightweight panel.

What is it Made Of?

This duct is a sandwich panel with three key layers:

Aluminum Facings: Both the inner and outer surfaces are covered with a layer of aluminum foil or sheet. This provides a smooth, hygienic, and corrosion-resistant surface. The aluminum foil is typically 60 to 80 microns thick for indoor use, but a thicker aluminum sheet or additional coating may be used for more demanding or external environments.

Polyurethane (PU) Foam Core: The middle layer is a rigid PU foam that serves as the primary thermal insulator. Its closed-cell structure also makes the panel waterproof and provides good sound insulation.

Environmentally Friendly Foam: The PU foam is often manufactured without CFCs or HCFCs, which are harmful to the ozone layer.

Environmental Friendliness of Polyurethane PID Panels

This Polyurethane PID Panels is produced using environmentally sustainable raw feedstocks with strict control over harmful chemical compositions.

It achieves zero discharge of toxic volatile organic compounds (VOCs) throughout its service life and maintains an extremely low formaldehyde concentration that meets mainstream international indoor environmental certifications.

Boasting reliable safety performance and excellent health compatibility, the product is well-suited for indoor HVAC ventilation duct systems across all categories of occupied construction projects, covering civil residential buildings, commercial premises, institutional facilities and public service buildings, effectively avoiding indoor air pollution risks caused by ductwork materials.

How does the Polyurethane PID Panels perform in terms of energy efficiency?

1.The Polyurethane PID Panels 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, it achieves higher energy utilization rate and saves more operational costs year-round.

Project Case of UNT Ductwork

PRE-INSULATED DUCT vs G.I. DUCTWORK

Metric	20mm PU Pre - Insulated Duct (with 0.08mm Alu. Foil, )	0.5mm G.I Duct + 30mm Rubber Plastic (40-90kg/m³)
Fire Safety	Compliant (Class 0/BS 476, AS 1530.3). Self-extinguishing PU core, low toxic smoke, non-combustible alu foil.	G.I non-combustible; rubber plastic fire-retardant but requires coating to meet strict codes.G.I
Thermal Insulation	Excellent. λ=0.020 W/m·K, no thermal bridging. 20mm integrated structure ensures consistent insulation.	Fair. λ=0.035 W/m·K, thermal bridging at G.I joints. 30mm insulation offset by metal conductivity.
Hygiene & Air Quality	Superior. Non-porous alu foil, smooth inner surface, moisture-resistant PU. Meets cleanroom/hospital standards.	Poor. Porous rubber plastic traps dust/mold; G.I-insulation gaps breed pathogens.
Lightweight	1.4-1.5 kg/m². Ultra-light, reduces structural load; ideal for retrofits/timber-framed buildings.	5.1–6.3 kg/m². Heavy G.I base + bulk insulation; requires reinforced supports.
Energy Efficiency	Excellent. 20–30% lower HVAC energy consumption. Minimizes heat gain/loss in conditioned air.	Low. 20–30% higher energy loss due to inferior insulation and thermal bridging.
Ease of Construction	Easy. Factory-prefabricated tongue-and-groove joints. No separate insulation step; 40–60% less labor time.	Complex. Two-step on-site process: G.I duct fabrication + rubber plastic wrapping. Labor-intensive, prone to gaps.
Quiet Operation	Good. PU core absorbs 10–15 dB airflow noise; alu foil dampens vibration.	Fair. Rubber plastic provides basic sound reduction, but G.I vibration and insulation gaps reduce efficiency.
Space Savings	Excellent. 20mm total thickness (all-in-one). Fits tight ceilings/retrofit cavities.	Poor. 30.5mm total thickness (0.5mm G.I + 30mm insulation). Bulky, requires larger installation space.
Environmental Friendliness	Balanced. CFC/HCFC-free PU, recyclable alu foil. 20–30-year lifespan; net carbon positive in 1–3 years.	Low. Rubber plastic non-recyclable; 10–15-year lifespan. Frequent replacement increases waste; higher energy emissions.
Air Leakage	Superior. ≤2% air leakage (EN 1507, AS/NZS 3660.1). Airtight factory joints + alu foil vapor barrier.	Poor. 5–10% air leakage. On-site sealing gaps; separate vapor barrier required.

Performance comparison based on UNT Duct product data and standard system configurations. Actual performance may vary depending on system design, installation method and project conditions.
