3-fold variable sealing foil for internal and external sealing

Film sealing for all situations

ISO-CONNECT VARIOFLEX SD+ is a highly flexible and stretchy special foil that can be used for connection joints for- windows, doors and panels to create a seal that is airtight and windproof. ISO-CONNECT VARIOFLEX SD+ is made from a pliable soft polymer fleece and is self-adhesive over the entire surface. When the fold (20 mm) is closed, the foil is used as a COMPLETE foil with adhesive tape applied on one side. Opening the fold (20 mm) creates the COMPLETE DUO foil with self-adhesive strips on alternating sides. A single foil can thus be used for all sealing applications between window frame and building structure.

Application Areas

Easier, faster, more flexible

ISO-CONNECT VARIOFLEX SD+ is used in the interior and exterior of buildings for bonding over window connection joints; with its variable sd-value, it is particularly adaptable to the substrate. The principle of “tighter on the inside than on the outside” is therefore guaranteed at all times and in any climate. The foil creates a reliable seal for movement joints. As it is extremely good for absorbing movement whilst offering high tensile strength, it can compensate even for significant component movements.
