VARA Seal is a humidity-variable airtight sealing tape used at membrane overlaps, window and door connections, and detail junctions.
Its Sd value varies with ambient humidity (0.4–30 m), so the tape regulates moisture flow at the joint the same way Vara Plus does at the membrane field — drying in summer, vapour-resistant in winter. The acrylic adhesive bonds to membranes, wood, masonry, concrete, plaster, PVC, and metal, and the tape can be plastered over for clean, hidden installations.
