Description
Soudal Soudatape Flex Airtight Sealing Tape
Soudal Soudatape Flex is a flexible airtight sealing tape designed for the permanent sealing of penetrations and overlaps in interior applications. Its elastic construction makes it particularly suitable for creating airtight and vapour-retarding seals around pipes, tubes, beams and other service penetrations through vapour barriers and construction membranes. Featuring a solvent-free adhesive with excellent ageing resistance, Soudatape Flex delivers durable adhesion to common building materials including foils, non-woven materials, wood and aluminium.
