What Is Butyl Tape?

Butyl tape is a type of rubber-based adhesive made from synthetic rubber, known for its strong adhesion properties and flexibility. Unlike other adhesives such as silicone or acrylic, butyl tape maintains its stickiness even at lower temperatures, making it perfect for a variety of applications. It bonds instantly to most surfaces, including wood, glass, metal, and plastic, providing a waterproof seal that protects against the elements.
One of the key advantages of butyl tape is that it adheres well in areas where moisture is present, such as decks and roofing systems. Butyl rubber tape is highly durable and flexible, making it the preferred choice for builders and homeowners alike, especially for deck substructures and other outdoor projects.

Butyl tape is incredibly versatile and can be used in various applications, including:
- Home repairs: Effective for sealing around windows, doors, or other openings.
- Roofing applications: Works well for both rubber roofing and metal roofing to prevent water damage.
- Industrial uses: Can be applied to glass, metal, and plastics in manufacturing settings.
Key notes on Butyl Tape:
- Strong adhesion: Bonds securely to even challenging surfaces, including timber, metal, and rubber.
