With Soudal Soudatape Flex, you create a reliable and durable airtight seal for interior insulation projects. This elastic sealing tape is specially designed to seal penetrations of pipes, cables, and beams through vapour barriers and foils. Thanks to its flexible backing, the tape moulds easily around irregular contours, while the fibre-reinforced structure prevents tearing during application. The powerful, solvent-free adhesive provides strong bonding to vapour control layers, timber, aluminium, and pvc. By creating an airtight barrier, you prevent heat loss, draughts, and condensation damage in the insulation structure. Apply the tape firmly onto clean surfaces for long-lasting performance.
