PIR Pre-insulated Ductwork Panel

 

PIR Pre-insulated Ductwork Panels are advanced materials designed for HVAC (Heating, Ventilation, and Air Conditioning) duct systems, combining thermal insulation, fire resistance, and durability. Below is a detailed introduction based on technical specifications and industry applications:

Core Structure & Material Composition:

PIR (Polyisocyanurate) Pre-insulated Duct Panels feature a sandwich construction:

Core Material: PIR foam, a high-performance rigid insulation with a closed-cell rate of 95%, providing exceptional thermal insulation (thermal conductivity: 0.022 W/m·K).

Facings:

Aluminum Foil: Standard thickness 60 or 80 microns, with options for 150 to 200 micron aluminum sheets or pre-painted galvanized iron (GI) sheets for external use.

Antibacterial Coating: Available on surfaces of aluminum foil for hygienic environments (e.g., hospitals, pharmaceuticals).

External /Internal Use:

Panel Structure: Silver Alu. / PIR Foam / Silver Alu. 

Foam Density: 55kg/m3

Panel Dimension: 3950mm*1200mm*20mm

Alu. Foil: 60 Micron (Embossed)

Painted Steel Sheet : 180 Micron (Smooth)

1. Thermal Efficiency:

PIR foam outperforms traditional materials like galvanized steel (GI) ducting (thermal conductivity: 0.028–0.037 W/m·K).

Maintains stability in temperature ranges from -150°C to +80°C, with continuous operation up to 70°C.

2. Fire Safety:

Fire rating: BS 476 Class 0 (UK) or B1 (GB 8624-2006) (China), meeting stringent international standards.

Non-toxic smoke emission and CFC/HCFC-free, ensuring environmental compliance.

3. Durability & Hygiene:

Corrosion-resistant aluminum facings prevent rust and condensation.

Service life exceeds 20 years with minimal maintenance.

4. Lightweight & Easy Installation:

Weighs approximately 1/7th of traditional GI ducting, reducing transportation and labor costs.

Single-fix installation process with specialized cutting machines for airtight seals.
