Product Overview

• Our phenolic duct board is a high-performance pre-insulated duct material made of rigid phenolic foam core with double-sided aluminum foil facing.

• It is designed to replace traditional galvanized steel ducts and fiberglass insulated ducts, providing better thermal insulation, fire safety and energy efficiency.

• Widely used in commercial buildings, hospitals, laboratories, pharmaceutical factories, food processing plants and industrial ventilation systems.

• As a leading phenolic duct board manufacturer in China with over 40 years of experience, we offer customized solutions to meet your specific project requirements.

Core Advantages

1. Superior Fire Performance

• Class A fire rated according to EN 13501-1, UL 94 V-0 and ASTM E84 standards

• Self-extinguishing, no molten droplets, low smoke emission, non-toxic fumes

• Unlike fiberglass ducts which can release toxic smoke when burned, our phenolic duct board produces minimal smoke and no harmful gases, ensuring the safety of building occupants

• Ideal for high-rise buildings, hospitals, schools and other public places with strict fire safety requirements

2. Excellent Thermal Insulation Performance

• Thermal conductivity λ=0.023 W/m·K at 20℃, one of the lowest among all insulation materials

• Reduces energy consumption by up to 30% compared to traditional galvanized steel ducts with separate insulation

• Excellent moisture resistance, prevents condensation on duct surfaces even in high humidity environments

• Thermal performance remains stable over time, no degradation after 50 years of use

3. Lightweight & High Strength, Significantly Reduces Installation Costs

• Only 3-5 kg/㎡, approximately 1/10 the weight of galvanized steel duct systems

• Easy to cut, shape and install on site, no heavy lifting equipment required

• 50% faster installation than traditional duct systems, significantly reducing labor costs

• High compressive strength, can withstand normal handling and installation without damage

4. Superior Indoor Air Quality

• Unlike fiberglass ducts, phenolic foam does not release fibers into the air, preventing respiratory problems

• Inherently resistant to mold, mildew and bacteria growth

• Smooth aluminum foil surface is easy to clean and maintain

• Meets the air quality requirements of hospitals, pharmaceutical factories and food processing plants

5. Long Service Life & Low Maintenance Costs

• 50+ years service life, much longer than traditional duct systems

• Resistant to corrosion, rust and chemical attack

• No need for regular painting or insulation replacement

• 100% recyclable, CFC and HCFC free, environmentally friendly
