Delta Duct Aluminum Foil Tape

High Adhesion • Moisture Resistant • HVAC Grade

Delta Duct Aluminum Foil Tape is a nominal dead soft aluminum foil coated with a high-performance synthetic rubber–resin adhesive, protected by an easy-release liner. Designed for professional HVAC and industrial applications, this tape provides exceptional sealing, holding, splicing, and masking performance in environments requiring high moisture and vapor resistance.

Key Features

Excellent peel adhesion for long-lasting bond strength
Permanent bonding suitable for demanding temperature and pressure conditions
Good water and fire resistance for enhanced safety
Excellent aging resistance ensures long-term durability
Ideal for sealing joints, seams, and insulation jackets in HVAC systems

Applications

Delta Duct Aluminum Foil Tape is designed for high-performance sealing and insulation applications across multiple HVAC and industrial systems, including:

Sealing joints and seams on foil jacketing insulation to prevent moisture and vapor intrusion
Permanent sealing and holding in ducting and ventilation systems
Splicing or masking applications requiring foil-backed surface protection
HVAC duct insulation wrapping and vapor barrier sealing

Note: For optimal adhesion, ensure the surface is clean, dry, and free from oil and grease before application.
