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

Foam Density: 52kg/m3

Panel Dimension: 3950mm*1200mm*20mm

Alu. Foil Thickness: 60 or 80 microns (smooth or embossed)

Packing: 10 sheets/ package

What are the key features and benefits of Polyisocyanurate (PIR) Foam Pre-insulated Aluminum Duct Panel?

1. Low Thermal Conductivity (PIR Foam Core)

Feature: Closed-cell PIR foam core with ultra-low thermal conductivity (0.022 W/m·K) and high R-value (R-5 to R-8 per inch).

Benefit: Minimizes heat gain/loss for conditioned air (cooled/heated), cutting HVAC energy consumption by 20–30% vs. traditional insulated metal ducts. Lowers utility bills and helps meet strict energy codes or green building standards.

2. Fire-Retardant Design

Feature: Inherently flame-retardant PIR foam, meeting global safety standards (Class 0 per BS 476 Part 6/7; Class B1 per GB 8624). Forms a self-extinguishing char layer when exposed to fire, reducing smoke production.

Benefit: Eliminates fire risks of porous insulations (e.g., fiberglass, which melts and releases toxic smoke). Enhances building safety and ensures compliance with commercial/institutional fire codes (critical for hospitals, schools, malls).

3. Airtight & Moisture-Resistant Structure

Feature:

Using aluminum ro PVC flange joints for tight seals (air leakage ≤2% per EN 1507).

Closed-cell foam core (water absorption <1% by volume) + impermeable facings (aluminum/ painted steel).

Benefit:

Prevents air leakage (a top cause of HVAC inefficiency) to maintain consistent indoor temperatures.

Blocks moisture intrusion, avoiding mold growth, metal corrosion, and insulation degradation-extending duct lifespan to 20–30 years (vs. 15–20 years for traditional ducts).

4. Rigid & Lightweight Construction

Feature: Dense PIR foam core (52kg/m³) for structural rigidity; total weight of 1.4 kg/m² (70–80% lighter than insulated metal ducts).

Benefit:

Resists sagging, punctures, or deformation-no need for extra structural supports.

Reduces transportation/installation costs: no heavy lifting equipment required; cuts assembly time by 40–60% (easily cut with standard tools like circular saws).

5. Durable, Low-Maintenance Facings

Feature: Protective facings (aluminum, galvanized steel) bonded with solvent-free, fire-retardant adhesive (no delamination over time).

Benefit:

Corrosion-resistant (ideal for humid spaces like hospitals or coastal buildings) and UV-stable (suitable for outdoor use with coatings).

Minimal upkeep: Wipe clean with mild detergent-no repainting, re-insulation, or rust repairs.

6. Hygienic & Eco-Friendly Options

Feature:

Non-porous FRP/aluminum facings (prevent dirt/bacteria buildup, meeting food processing/cleanroom standards).

CFC/HCFC-free foam, recyclable materials (aluminum/PIR), and low-VOC adhesives.

Benefit:

Improves indoor air quality (IAQ) by reducing allergen/microbe growth-critical for healthcare or schools.

Aligns with sustainability goals: Reduces ozone depletion, landfill waste, and indoor air pollution.

In short, these features make Rigid PIR Pre-Insulated Aluminum Ductwork a cost-effective, safe, and sustainable choice for modern HVAC systems-delivering long-term value for building owners, contractors, and the environment.
