-
Applications: sealing windows, doors, roofs, joints, roofing membranes.
2. Double-Sided Butyl Tape
-
Features: adhesive on both sides – perfect for bonding two elements.
-
Advantages: strong and durable adhesion, resistant to vibration and moisture.
-
Applications: mounting photovoltaic panels, windows, mirrors, car body parts.
3. Reinforced Butyl Tape
-
Features: reinforced with fleece or aluminum for increased strength.
-
Advantages: high durability, UV resistance, mechanical strength.
-
Applications: roofs, chimneys, flashing, waterproof insulation.
4. Butyl Cord
-
Features: flexible cord form – easy to shape and model.
-
Advantages: perfectly fills gaps, can be shaped by hand.
-
Applications: sealing installations, expansion joints, window connections.
🏠 Where to Use Each Type of Butyl Tape?
| Type of tape | Main purpose | Example applications |
|---|---|---|
| Single-sided | Surface sealing | Flashings, windows, roofs, membranes |
| Double-sided | Joining two elements | PV panels, windows, mirrors, automotive components |
| Reinforced | High-load or UV-exposed areas | Roofs, chimneys, sheet metal joints, thermal insulation |
| Butyl cord | Filling gaps and openings | Pipes, windows, doors, expansion joints, installations |
