Low Thermal Conductivity: GFI HVAC Phenolic PI Duct With low thermal conductivity of 0.018-0.022W/(m·k), GFI’s panels offer best-in-class insulation, minimizing heat transfer for enhanced efficiency.Fire Resistance: Our Phenolic Coating HVAC Duct creates a protective char layer when exposed to flame, effectively isolating the material beneath and limiting flame spread. This property, coupled with low toxic gas emission, promotes a safer environment.Moisture and Mold Resistance: ThePhenolic Duct Board are resistant to moisture and microbial growth, making them durable and hygienic for HVAC applications.Enhanced Durability and Lightweight Construction: These Phenolic Foam Duct weigh less than traditional metal ductwork yet offer high strength, longer lifespan, and improved efficiency, making installation simpler and system performance more reliable.High Density: About Phenolic Foam Strength and Density, each panel is constructed with 20mm of closed-cell Phenolic Foam Insulation, laminated with a robust 80-micron aluminum foil available in silver or black. The foil is embossed on both sides and protected with a 2g/㎡ corrosion-resistant epoxy varnish coating, enhancing the panel’s durability and fire-resistant properties.
