Effisus Adjoin TI Tape

Unsealed overlaps, penetrations and joints between membranes are among the leading causes of air leakage and moisture infiltration in building envelopes. Over time, structural movement, temperature variation, and weather exposure can weaken these joints, compromising airtightness, waterproofing, and overall energy efficiency. Poor sealing also increases the risk of condensation and long-term material deterioration.

Effisus Adjoin TI Tape effectively eliminates these vulnerabilities by forming a durable, airtight, and waterproof bond between vapour barriers, breather membranes, and multiple construction substrates. Its advanced, solvent- and softener-free acrylate adhesive ensures lasting adhesion in both indoor and outdoor environments, maintaining performance even under thermal or structural stress.

Highly elastic and easy to apply, the tape reliably seals overlap, butt joints, and complex details such as windows, doors, corners, and roof penetrations. The result is a robust, flexible, and maintenance-free seal that enhances the integrity and energy efficiency of the entire building envelope.

Effisus Adjoin TI Tape was tested and certified as an integral component of the Effisus Breather FR-B and Effisus Breather FR UV Systems.
