Product description

Product advantages

ISO-CONNECT INSIDE CX is a special water resistant and vapour diffusion impermeable foil for an air tight and wind proof sealant on connecting joints in

  • windows
  • doors
  • panels

in accordance to the new energy saving regulation (EnEV) requirements. It consists of a synthetic fleece with a self adhesive strip on one edge for a quick and effective application on window frames.

  • Complies with the requirements of the new energy saving regulations (EnEV)
  • Airtight, wind proof and water vapour impermeable water resistant
  • Special fleece surface which is good for plastering, painting or pasting over
  • With a self-adhesive strip for quick and effective installation
  • Highly flexible, but with a high tensile strength for an easy and exact application
  • 10 year performance guarantee*
*On the conditions of the manufacturer (available upon request).



ISO-CONNECT INSIDE CX is used to seal internal connecting joints. Due to its large sd-value it is suitable for sealing joints where an impermeable vapour diffusion, and airtight, seal is required, separating the internal and external air conditions. ISO-CONNECT INSIDE CX is highly flexible, which aids exact application, particularly around corners. It also allows the optimum bonding of wet plaster, paint, etc. (without the need of a primer), and is extremely suitable as a base for thermal insulation materials applied to internal facades.
  • Standard sizes available from stock
  • Private label and/or special labelling available
  • Competent technical support available in the field and by phone

The bonding surfaces must be firm, dry, clean from dust, stripping agents, solvents, oil and grease. When sealing windows, panels and door frames remove backing from the self-adhesive strip, then lay the foil onto the surface and press securely. ISO-CONNECT INSIDE CX can be applied in the factory.

For wall applications ISO-TOP FLEX-ADHESIVE SP or SP+ is used. Normal rough, e.g. uneven wall surfaces, can be compensated for by the application of sufficient adhesive. Use enough adhesive so that after applying the foil the adhesive caterpillar is at least 30 mm wide and 1 mm thick. On areas that are to be plastered over a continuous „Z“ shaped caterpillar should be applied over the area. Depending on the μ-values of the surface it can be necessary to increase the width of the adhesive caterpillar up to > 50 mm, in order to reduce the water vapour permeability. Overlapping of the foil ends should only be up to 50 mm wide using the same technique. Plastering can be done as soon as the adhesive bond is enough to carry the plaster.
