TESCON VANA air sealing tape is a long-lasting, robust solution for building airtightness. Learn what we mean by “permanently airtight”: third-party tested for highest possible performance. It may be used both interior and exterior with an array of materials:
Pro Clima smart vapor retarders (INTELLO, DB+)
Pro Clima Weather Resistant Barriers
Housewraps and ZIP-system
TESCON VANA has the following properties:
Seals joints airtight between wood based panels (such as OSB and plywood).
Vapor permeable, Perm 8 (Sd value:0.4m) for enhanced outward drying potential.
3.9″(100) and 5.9″(150) have split release paper, for easy application on two sides of seams, inside corners, etc.
Durable waterproof tape adhesion (SOLID acrylic adhesive).
In combination with TESCON Primers adheres to soft/porous wood insulation panels, concrete, sheetrock, rough OSB and brick.
UV/weather resistant – 6 months of exposure.
Very high tensile strength.
Polypropylene backing forms itself to slightly uneven substrates.
