2026-04-21 08:56:16

Introduction

aluminum foil composite materials have become the material of choice for HVAC duct manufacturing, offering excellent thermal reflectivity, moisture barrier properties, and cost-effectiveness.

Why Aluminum Foil for HVAC Ducts?

1. Thermal Insulation: Reflective surface radiates up to 97% of heat back.
2. Moisture Barrier: Virtually impermeable to water vapor.
3. Structural Integrity: Strength and flexibility for duct fabrication.

Material Options

1. Single Side AL/PET

The most economical option. Single Side Silver Duct Foil offers high thermal reflectivity for residential HVAC.

2. Double Side AL+PET+AL

Double Side Silver Duct Foil provides reflective surfaces on both sides for maximum thermal performance.

3. PVC Laminated

PVC laminated aluminum foil offers enhanced chemical resistance for kitchen ventilation and industrial exhaust.

4. VMPET

VMPET for Flexible Duct is a cost-effective alternative for budget-sensitive projects.

5. Fiber Glass Mesh

Fiber Glass Mesh Foil adds exceptional tear resistance for large-diameter ducts.
