Reliably separation of interior and exterior climate with high elasticity and flexible adaptation
ISO-CONNECT INSIDE CL is an extremely flexible, stretchable and tearproof special foil with very high adhesion that can be used for connection joints on windows, doors and panels to create a seal that is airtight and windproof.

ISO-CONNECT INSIDE CL is made from a pliable soft synthetic fleece. It is self-adhesive over the entire surface and has a self-adhesive
strip to aid fitting. The fleece foil creates a vapour barrier that reliably separates the interior climate from the exterior. ISO-CONNECT INSIDE CL complies with the requirements of the Building Energy Act GEG and the RAL “installation guide”.

Reliable sealing of window connection joints in case of strong component movements
ISO-CONNECT INSIDE CL is used inside buildings for gluing over window connection joints; it adapts especially well to the substrate. This inside foil creates a reliable seal for movement joints. As it is extremely good for absorbing movement whilst offering high tensile strength, even significant component movements can be permanently compensated with this flexible window connection foil.
