Decade of PIR Foam Pre-insulated Duct Factory
PU/PIR ducts are constructed with a core of rigid polyurethane (PU) or polyisocyanurate (PIR) insulation foam, encased between aluminum foil or galvanized iron sheets. The outer layer features high-purity thin aluminum, while the core consists of flame-retardant PU foam. PU pre-insulated duct boards offer exceptional strength, B1-level flame resistance, waterproof and moisture-resistant properties, and a pollution-free composition, ensuring long-term stability and reliable performance.
GFI HVAC operates its own advanced manufacturing facility dedicated to producing high-quality HVAC PID ducts. These ducts are available in thicknesses ranging from 10mm to 40mm, catering to diverse insulation and structural requirements in commercial and industrial HVAC applications.
To meet different environmental and durability needs, GFI HVAC offers multiple surface options for PID ducts:
Double-Sided Aluminum Foil - Provides excellent thermal insulation, corrosion resistance, and lightweight performance.
Black Aluminum Foil - Designed for applications requiring enhanced UV resistance and an aesthetically discreet finish.
Aluminum Sheets Coated - Features a protective coating for increased durability and resistance to oxidation.
Smooth Aluminum Foil - Ensures a sleek surface with optimal insulation efficiency and moisture resistance.
200-Micron GI Coating - Reinforced with a galvanized iron coating for superior mechanical strength and impact resistance.
With precise manufacturing processes and stringent quality control, GFI HVAC ensures that its PID ducts deliver outstanding thermal insulation, fire resistance, and long-term reliability for various HVAC systems.
Join the countless satisfied customers worldwide who have made the switch to our PU PIR Foam Insulation Panel for a greener and more efficient HVAC duct system.
