Aluminum foil tape is a high-strength, pressure-sensitive adhesive tape used primarily for sealing, shielding, and repairing. It consists of a thin layer of aluminum foil (the carrier) backed by a strong, often cold-weather acrylic adhesive.
Key Features
- Heat & Flame Resistance: Naturally withstands high temperatures and acts as an excellent thermal insulator.
- Moisture & Vapor Barrier: Provides an airtight and watertight seal, preventing leaks and corrosion.
- Highly Conformable: Easily molds to irregular surfaces, corners, and joints.
- Reflective Properties: Reflects both light and heat, making it energy-efficient for HVAC and insulation projects.
- Durability: Resistant to UV degradation, chemicals, and aging.
Common Applications
- HVAC Systems: Sealing joints and seams in air ducts to prevent air leaks and improve efficiency.
- Insulation: Joining foil-backed fiberglass or foam board insulation.
- General Repair: Patching gutters, roofing, or metal surfaces.
- Shielding: Protecting sensitive components from heat or electromagnetic interference (EMI).
