MarkQ Aluminum Foil Tape, 2" × 15 yd, HVAC-Grade Acrylic Adhesive & Vapor Seal

Adhesive: high-tack acrylic that bonds to metal, foil, and insulation facings. Backing: aluminum foil. Dimensions: 2" (width) × 15 yd (length). Features: conformable foil backing, air- and vapor-tight seal, and code-ready performance for HVAC duct sealing. It’s designed to withstand temperature cycling and UV exposure.

It sticks well to metal, foil, and insulation facings commonly found in HVAC ductwork and foil-backed insulation. For best results, ensure surfaces are clean, dry, and free of dust or oils before applying.

Clean the surface, cut the tape to the desired length, and apply with firm pressure along the seam or area to be sealed. Smooth from the center outward to remove air pockets, and wrap seams with overlap if needed to ensure a continuous seal.

Yes. The foil backing is conformable, allowing it to mold around corners, ridges, and irregular surfaces for a tight, uniform seal.

Yes. It is described as code-ready for HVAC duct sealing and designed to meet typical standards for durable, air- and vapor-tight seams in ductwork.

Compared with standard cloth or plastic duct tapes, the aluminum tape offers better resistance to temperature cycling, moisture, and UV exposure, plus a more reliable vapor seal. It’s generally more durable for long-term duct sealing and radiant barrier applications.

Sealing duct seams, securing foil-faced insulation in HVAC installations, repairing minor gaps in radiant barriers, and closing penetrations in metal or foil-based surfaces where a durable, vapor-tight seal is needed.

Use scissors or a sharp utility knife to cut clean edges. Apply along the contour of the corner or edge with steady pressure, pressing firmly to ensure full contact and minimize gaps.

Treat like other HVAC tapes: store in a cool, dry place, avoid contact with flames or excessive heat during application, and handle with standard care to prevent cuts from the foil edges. No special safety equipment is required beyond normal precautions.

The tape is designed to maintain air- and vapor-tight seams through temperature cycling and UV exposure common in HVAC environments. Its durability supports long-term performance in ducts and foil-facing installations.
