Phenolic Pre-Insulated Duct for a Garment Factory in Vietnam

GFI is pleased to announce the successful supply of Phenolic Pre-Insulated Duct Panels (GI + Aluminum Foil Composite) for a major garment manufacturing facility in Vietnam. This project marks another milestone in GFI’s continuous support for industrial HVAC upgrades across Southeast Asia, particularly for facilities that require reliable air distribution, enhanced fire safety, and long-term energy efficiency.

A High-Demand Environment That Requires Reliable HVAC Performance

Garment factories typically operate under high internal heat load, continuous ventilation requirements, and strict environmental demands for employee comfort.

To meet these conditions, the project required a ducting solution that provides:

• Stable airflow across large workshop areas
• Excellent thermal insulation
• Strong fire performance
• Long service life, even under continuous operation
• Lightweight materials that reduce structural load

GFI’s Phenolic Pre-Insulated Duct Panel, featuring one-side pre-painting GI sheet (200 micron) and one-side embossed aluminum foil (80 micron), proved to be the ideal solution.

Why the Project Selected GFI Phenolic GI-Faced Duct Panels

1. Superior Fire Performance for Industrial Applications

Phenolic foam offers one of the lowest thermal conductivities among insulation materials (0.018–0.022 W/m·K) while providing Class 0 / Class A fire ratings.

For textile production environments—where safety standards are strict—its ability to form a protective char layer is especially valuable.

2. Higher Compressive Strength with GI Sheet Facing

The pre-painting GI sheet significantly enhances panel rigidity, making the ductwork more durable and suitable for:

• Large workshop spans
• Long duct runs
• Outdoor or rooftop sections
• Areas where maintenance traffic is common

This GI-faced structure provides better impact resistance than aluminum-only phenolic panels.

3. Lightweight, Efficient, and Easy to Install

Compared with traditional galvanized steel ducts, GFI phenolic duct panels offer:

• Faster installation speed
• Lower installation labor
• Reduced structural load on ceilings and supports
• Cleaner fabrication using tracing, cutting, folding, taping, and flanging

These benefits allowed the Vietnam project to complete installation efficiently with minimal production downtime.

Project Highlights

Although project-specific details remain confidential, the supplied system includes:

• Phenolic Pre-Insulated Duct Panels (GI + Aluminum Foil Composite)
• Standard accessories for fabrication and reinforcement
• Support for both manual fabrication (GFI Tool Box) and CNC cutting processes

The installed duct system is now contributing to stable ventilation performance across the garment workshop, helping maintain a comfortable working environment and supporting the factory’s long-term energy management goals.

A Growing Demand for Phenolic Pre-Insulated Ductwork in Vietnam

Vietnam’s industrial sector—especially textiles, electronics, and food manufacturing—has shown increasing interest in:

• High-efficiency duct materials
• Fire-resistant duct systems
• Lightweight HVAC components
• Faster installation solutions for expanding factories

GFI’s phenolic duct panels continue to be widely adopted due to their balance of safety, efficiency, durability, and cost-effectiveness.
