PID PIR Panel Duct

With high-performance PIR foam serving as its core substrate, PID PIR Panel Duct are lightweight composite components. Uniting thermal insulation performance, mechanical stability and certified fire protection in a single integrated structure, they enjoy extensive use across HVAC construction projects.

Adopting a modular all-in-one design, this duct solution lowers system energy waste, shortens on-site assembly time, and maintains reliable ventilation efficiency over prolonged operation.

Environmental Friendliness of PID PIR Panel Duct

PID PIR Panel Duct material 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.

Advantages of PID PIR Panel Duct

1.Ultra-Light Construction

Weighing merely 1/4 to 1/3 of galvanized steel ductwork, it lessens loads on building structures and slashes manpower costs during installation.

2.Superior Thermal Insulation

Built with a PIR foam core featuring thermal conductivity of 0.02–0.025 W/m·K, it effectively blocks heat transfer and removes the need for supplementary external insulation layers.

3.Exceptional Air Tightness

Fully sealed flanges and taped joints drastically cut air leakage, significantly lifting the overall energy efficiency of HVAC systems.

4.Corrosion & Moisture Resistance

Outer aluminum foil lamination resists rust, chemical erosion and humid environments, making it ideal for coastal zones and industrial premises.

5.Low Airflow Resistance

Smooth inner lining minimizes pressure loss in air circulation, lowering power consumption for ventilation fans.

6.Built-In Vapor Barrier

Integrated vapor retarder layer removes the extra step of installing standalone moisture barrier materials.

7.Easy On-Site Fabrication

Workable with basic hand tools: it can be cut, grooved and folded directly on site to speed up assembly procedures.

PRE-INSULATED DUCT vs G.I. DUCTWORK

Metric	20mm PIR 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 PIR 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 PIR. 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. PIR 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 PIR, 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.
