When it comes to sealing joints in construction, not all tapes are created equal. Choosing the right sealing tape can make the difference between a durable, weatherproof structure and one that suffers from moisture issues, air leaks, or poor insulation.
At Oskorp, we offer BG1 and 3E tapes—both designed for high-performance joint sealing, yet built for different applications. Understanding their differences will help you select the best solution for your project.
What is BG1 Tape?
BG1 is a heavy-duty joint sealing tape designed to provide long-lasting protection in structural applications. Whether you’re working on facades, expansion joints, or prefabricated construction, BG1 ensures airtightness, weatherproofing, and noise reduction—even under extreme conditions.
Key Benefits of BG1:
- Extreme Weather Resistance – Withstands driving rain up to 22 psf and tested for 15+ years of outdoor exposure.
- Superior Airtightness – Ensures windproof sealing while allowing vapor diffusion.
- High Thermal & Acoustic Insulation – Reduces energy loss and provides up to 59 dB sound insulation, perfect for noise reduction.
- Fire Safety Certified – Rated for low flammability and meets strict fire protection standards.
- Versatile Application – Ideal for facades, masonry, expansion joints, and wood construction.
📌 Best for: Heavy-duty structural joints, exterior facades, and expansion joints.
What is 3E Tape?
3E is a multi-functional joint sealing tape designed specifically for window and door installations. With its moisture-adaptive properties, it ensures airtight sealing while preventing condensation buildup, making it ideal for passive house applications and energy-efficient buildings.
Key Benefits of 3E:
- Moisture-Adaptive Technology – Adjusts to humidity levels, ensuring a dry joint year-round.
- Superior Airtightness – Seals windows and doors with zero air leakage, improving energy efficiency.
- Weather-Resistant – Protects against driving rain up to 22 psf, preventing water penetration.
- Fast & Easy Installation – Pre-compressed with a pressure-sensitive adhesive for quick application.
- Fire Safe & Low Emissions – Certified for halogen-free fire resistance and low VOC emissions.
📌 Best for: Window and door sealing, airtight construction, and energy-efficient buildings.
Final Verdict: The Right Tape for the Right Job
- Choose BG1 if you need long-term, heavy-duty joint sealing for facades, expansion joints, and masonry.
- Choose 3E if you need a fast, moisture-adaptive solution for windows and doors to prevent condensation and ensure airtightness.
Both tapes offer exceptional performance, but selecting the right one ensures a durable, efficient, and energy-saving building envelope.
