Key Features:
- Aggressive rubber adhesive: High-tack, pressure-sensitive rubber adhesive sticks well to most surfaces, including low-energy substrates.
- Vapor barrier: Soft aluminum foil conforms to irregular surfaces and provides a reliable vapor barrier.
- Duct sealing: Flexible and easy to apply in tight spaces, making it ideal for duct repairs.
- Easy unwind liner: Silicone-treated paper liner unwinds easily to minimize errors and wasted tape.
- Flame and smoke rated: UL 723 rated for flame and smoke characteristics.
- Weather resistant: Resists flame, moisture, weather, UV degradation, water vapor, odor and smoke transmission.
- Wide temperature range: Performs from -10°F to 180°F (-12.2°C to 82.2°C) and applies in most weather conditions.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Foil Tape 3311 is a solid choice where a code-conscious duct or insulation vapor seal is needed: the rubber adhesive grabs low-energy surfaces that acrylic tapes can struggle with. Apply to clean, dry surfaces and burnish the foil firmly to chase out air pockets at every seam. Note it is designed for long-term sealing on ducts and insulation rather than as a permanent structural metal repair. For big jobs, the 50 yd roll cuts cost per foot.
Cut foil edges are sharp; wear gloves when handling and cutting the tape, and apply within the stated temperature range for proper adhesion.
