100mm Knauf Aquapanel Exterior Joint Tape - Reinforcement Tape for Cement Boards - 50m roll

100mm Aquapanel Exterior Joint Tape is a high‑strength glass‑fibre reinforcement tape designed for securing and stabilising joints between Aquapanel Cement Board Outdoor panels. It forms part of the Knauf Aquapanel façade system, ensuring durable, crack‑resistant joints and a stable base for exterior finishing layers. The tape is embedded into Aquapanel Joint Filler – Exterior to reinforce board joints and prevent cracking caused by movement, thermal changes or structural stresses. Its open‑mesh glass‑fibre construction provides excellent tensile strength while maintaining compatibility with cement‑based fillers and renders.

Aquapanel Exterior Joint Tape is suitable for new‑build, refurbishment, and lightweight steel or timber‑frame constructions, ensuring long‑term stability of the façade system. It delivers reliable joint stability, excellent crack resistance, and full system compatibility, ensuring a robust and long‑lasting façade finish. Its ease of installation and proven performance make it a standard choice for professional Aquapanel installations.
