Frequently Asked Questions (FAQ)
Q
What is the most commonly used thickness for residential HVAC aluminum foil?
The most widely used thickness range for residential HVAC applications is 0.018mm – 0.03mm. This "common" range offers a balanced combination of flexibility and durability, making it ideal for main ducts and standard insulation wrapping in homes and light commercial buildings.
Q
Which aluminum alloy is best for high-temperature industrial exhaust ducts?
The 8011 Aluminum Alloy is the recommended choice for high-temperature industrial exhaust ducts and kitchen exhaust systems. Its iron (Fe) and silicon (Si) additions enhance stiffness and heat resistance, allowing it to withstand temperatures of 120–150℃ without degradation.
Q
What surface treatment should I choose for ducts in humid or coastal environments?
PE (Polyethylene)-coated foil is the best option for humid environments such as basements, coastal areas, or outdoor duct installations. The PE coating significantly enhances moisture resistance and prevents corrosion caused by condensation or high ambient humidity.
Q
Does the air duct aluminum foil meet international fire safety standards?
Yes. Fire-retardant coated foil variants are available and meet UL94 V-0 or equivalent international fire safety standards. These are specifically designed for use in public buildings such as shopping malls, hospitals, and high-rise structures where fire safety compliance is mandatory.
Q
Can the width of the aluminum foil be customized for special duct sizes?
Absolutely. In addition to standard widths of 1000mm, 1200mm, 1500mm, and 2000mm, custom widths ranging from 500mm to 2000mm are available upon request. Custom sizing minimizes material waste and ensures a precise fit for non-standard or special-sized ventilation systems.
Q
What quality certifications do top manufacturers' air duct aluminum foils carry?
Leading global manufacturers such as Alcoa, Novelis, Norsk Hydro, and Constellium produce air duct aluminum foils that comply with UL, CE, and ISO international standards. These certifications ensure consistent quality in formability, corrosion resistance, and thermal insulation performance for global construction and ventilation markets.
