TargoFLEX Airtight Sealing Tape – 50 mm
TargoFLEX 50 mm is a professional, highly flexible airtight sealing tape for reliable sealing in timber construction and interior applications — especially where membranes need to be connected around penetrations such as pipes, rafters, and cables. Thanks to its flexible composite film backing, the tape adapts extremely well to curves, edges, and slightly rough surfaces, supporting a long-lasting airtight installation in accordance with DIN 4108 / SIA 180.
Typical applications
-
Airtight sealing around rafter and pipe penetrations
-
Roof window connections
-
Airtight sealing/bonding to OSB boards
-
Moisture-exposed applications, e.g. façade areas (high wet strength)
Application notes
-
Substrates and materials must be dry, sound, and free of dust and grease.
-
Important: TargoFLEX is designed for sealing (not a structural/load-bearing bond). Therefore, connect membranes without tension and ensure sufficient overlap.
-
If tensile loads are expected, add mechanical fastening.
Key benefits
-
Extremely strong, ageing-resistant adhesion (lab-tested and proven in practice)
-
High wet strength — suitable for moisture-exposed areas
-
Highly flexible high-tech composite film — ideal for curves, edges, and slightly rough surfaces
