| Specification Category | Detailed Parameters | Application Scenarios | Key Notes |
|---|---|---|---|
| Thickness | Ultra-thin: 0.012mm - 0.015mm | Lightweight residential ducts, small-diameter flexible ducts | High flexibility, suitable for tight bending spaces |
| Common: 0.018mm - 0.03mm | Residential, commercial HVAC main ducts, standard insulation wrapping | Balanced flexibility and durability, most widely used | |
| Heavy-duty: 0.08mm - 0.2mm | Industrial ventilation ducts, high-temperature exhaust ducts | Enhanced tear resistance, adaptable to harsh environments | |
| Alloy Types | 1235 Aluminum Alloy (≥99.35% Al) | Residential duct wrapping, flexible duct cores, general insulation | Excellent flexibility and ductility, easy to cut and form |
| 1145 Aluminum Alloy | Commercial ducts, medium-sized ventilation systems | Higher strength and tear resistance than 1235 alloy | |
| 8011 Aluminum Alloy (with Fe, Si additions) | Industrial exhaust ducts, high-temperature HVAC systems (e.g., kitchen exhaust) | Enhanced stiffness and heat resistance, withstands 120 - 150°C | |
| Surface Treatments | Plain Foil (Uncoated) | Indoor dry environment ducts, temporary duct insulation | Cost-effective, basic protection performance |
| Acrylic-coated Foil | Insulation layer bonding, duct liners | Improves adhesion to glass wool/rock wool, prevents delamination | |
| PE (Polyethylene)-coated Foil | Humid environments (basements, coastal areas), outdoor ducts | Enhanced moisture resistance, avoids corrosion from condensation | |
| Fire-retardant Coated Foil | Public buildings (malls, hospitals), high-rise building ducts | Meets UL94 V-0 or equivalent fire safety standards | |
| Width | Standard Widths: 1000mm, 1200mm, 1500mm, 2000mm | Large-scale duct installation, batch insulation wrapping | Reduces splicing frequency, improves construction efficiency |
| Custom Widths: 500mm - 2000mm (on request) | Special-sized ducts, non-standard ventilation systems | Minimizes material waste, fits specific duct dimensions |
