Waterproof Aluminum Tape
Waterproof aluminum tape (also called waterproof foil tape, butyl aluminum tape, or rubberized aluminum tape) is a heavy-duty, metal-backed sealing tape designed to be 100% waterproof, airtight, and weatherproof — much more durable than standard thin HVAC foil tape.

FAQ
Q1, Is waterproof aluminum tape really 100% waterproof?
A1: Yes, especially the butyl rubber–based type. It forms a permanent, flexible, watertight seal that blocks rain, humidity, and liquid penetration far better than regular foil tape.
Q2, Can I use waterproof aluminum tape on wet surfaces?
A2: Most types require a clean, dry, dust-free surface for maximum adhesion. Some heavy-duty butyl aluminum tapes can stick to slightly damp surfaces, but they will not bond well or last if applied underwater or to soaking-wet material.
Q3. Is waterproof aluminum tape heat and cold resistant?
A3: Yes. It withstands high temperatures from heating ducts, sun exposure, and freezing outdoor conditions. It won't easily melt, crack, or peel in extreme weather.
Q4, Can waterproof aluminum tape be used for permanent repairs?
A4: Yes. It's designed for long-term outdoor and indoor repairs on roofs, gutters, pipes, HVAC ducts, RVs, and metal surfaces. It's much more durable than standard duct tape and resists aging, UV damage, and corrosion.
