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℃

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
