Intertape Polymer Group 99156 Foil Duct Tape 10 Mil

Product Description

The INTERTAPE POLYMER GROUP 99156 is a heavy-duty foil duct tape engineered for airtight and waterproof sealing on heating and air conditioning ductwork. At 10 mil thick, this cloth-backed metallic tape delivers extra-strength adhesion suited for demanding HVAC applications where standard tapes fall short. The silver foil construction resists moisture and air infiltration, helping maintain system efficiency by eliminating leaks at duct joints, seams, and transitions. HVAC technicians and insulation contractors reach for this tape when a durable, long-lasting seal is required on sheet metal or flexible duct assemblies.

This tape is designed for use on residential and light commercial HVAC duct systems, including supply and return air ducts, duct board, and related components. Beyond ductwork, it performs well in general-purpose applications requiring a waterproof, airtight bond on metal, foil-faced insulation, and similar surfaces. Its multipurpose nature makes it a practical addition to any service van or job-site toolkit.

Key Features

• 10 mil thickness provides extra-strength, tear-resistant performance on duct seams and joints
• Airtight and waterproof seal helps reduce energy loss and maintain system efficiency
• Silver foil facing is compatible with standard HVAC duct surfaces and insulation facings
• Multipurpose adhesive bonds to metal, foil, and related building materials
• Compact roll dimensions make it easy to carry and maneuver in tight plenum and attic spaces

Compatibility

Designed as a general-purpose foil duct tape suitable for use on heating and air conditioning ducts and related HVAC components across residential and light commercial installations.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors. Before applying, ensure all duct surfaces are clean, dry, and free of dust or grease for maximum adhesion. Power down the air handling system before working on ductwork to prevent debris from entering the airstream. Refer to local mechanical codes, including applicable SMACNA guidelines, for duct sealing requirements in your jurisdiction.
