Effisus 2Adjoin DF
Double-Sided Adhesive for Airtight Façade Sealing
In façade construction, even the smallest gaps between membranes and structural elements can lead to significant air leakage, moisture ingress, and loss of thermal efficiency. Effisus 2Adjoin DF Tape solves these challenges with a double-sided, airtight, and moisture-resistant adhesive.

Sealing overlaps between breather membranes

Sealing overlaps between vapour barriers
Over time, exposure to wind, rain, and temperature fluctuations can cause standard tapes to lose adhesion, compromising both a building’s performance and durability.
Effisus 2Adjoin DF Tape overcomes these challenges with a double-sided, airtight, and moisture-resistant adhesive specifically developed for fixing vapour barriers and breather membranes to façade structures, as well as for sealing membrane overlaps. It ensures a long-lasting bond between membranes and metal studs, PE/PA/PP, or aluminum foils, maintaining watertight and windtight integrity under all conditions.
Robust and with high life expectancy and easy application thanks to its release paper, this tape guarantees efficient and reliable sealing performance, providing a proven and durable solution for airtight and moisture-protected façade assemblies.
Effisus 2Bond DF Tape is part of the Effisus Façade Solutions range and an integral component of the Effisus A-Class Fire-Rated Façade System, fully tested and certified for these demanding applications.
When sealing on highly porous surfaces is required, Effisus 2Bond DS Sealing Tape is the ideal solution to consider.
