Aluminum Foil Tape | Heavy-Duty Waterproof Repair Tape for HVAC, Roofing & Ducts

Roof flashing coming loose? HVAC duct leaking air? This aluminum foil tape creates an airtight, waterproof seal that actually holds up. The heavy-duty adhesive sticks to metal, plastic, wood, and even slightly damp surfaces—something regular duct tape can't handle.

Each roll is 5cm wide and 10 meters long, giving you plenty of tape for repairs around the house or workshop. The aluminum backing reflects heat and resists moisture, making it perfect for sealing air ducts, patching roof leaks, insulating pipes, or weatherproofing outdoor equipment. It's non-toxic and won't degrade in sunlight or extreme temperatures.

Works great for emergency repairs too. Keep a roll in your garage, RV, or toolbox for when you need a quick fix that won't fail. Much stronger and more reliable than standard duct tape for anything involving heat, water, or outdoor exposure.
