Butyl waterproof tape

Seal, insulate, and protect with the Aluminium Foil Butyl Waterproof Sealing Tape an essential addition to any DIY toolkit. Crafted from premium aluminium foil paired with a thick layer of high-quality butyl rubber, this tape creates a durable, weatherproof barrier that effectively blocks leaks, drafts, and water seepage.

Ideal for sealing roof cracks, tank seams, window edges, bathroom joints, and air ducts, it adheres firmly to a wide range of surfaces including concrete, metal, plastic, and glass. The reflective aluminium foil layer not only adds strength but also helps resist UV damage, heat, and corrosion, extending the life of repairs even in harsh outdoor conditions.

Flexible yet strong, it’s easy to cut, shape, and apply, moulding around uneven or curved surfaces without losing adhesion. Whether fixing an old pipe, patching a wall crack, or waterproofing your caravan roof, this tape delivers reliable, long-lasting performance.
