Product description

Product advantages

ISO-CONNECT OUTSIDE CX is a special foil sealant which is air tight and impermeable to driving rain for connecting joints on

  • windows
  • doors
  • panels

in accordance to the new energy saving regulation (EnEV) requirements. It consists of a water vapour diffusion permeable synthetic fleece with a self adhesive strip on one edge for a quick and effective application on window frames. After installation ISO-CONNECT OUTSIDE CX can be plastered over.

  • Fulfils the EnEV (energy saving regulations) requirements
  • Air tight and wind proof, water vapour permeable
  • Driving rain and 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 OUTSIDE CX is used to seal external connecting joints, for weather protection in areas where vapour diffusion permeability is required. It allows trapped moisture in building joints to escape, according to the RAL installation guidlines, avoiding damage caused through condensation. ISO-CONNECT OUTSIDE CX is highly flexible, which aids exact application, particularly around corners. It also allows the optimum bonding of wet plaster, render etc. (without the need of a primer), and is extremely suitable as a base for thermal insulation materials applied to external 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 fat. 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 OUTSIDE CX can be applied in the factory.

For the wall applications ISO-TOP FLEX-ADHESIVE SP or SP+ is used. Normal rough, e.g. uneven wall surfaces, can be compensated for through the application of a sufficient amount of adhesive. Use sufficient 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. 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.

Single side self-adhesive with 1 self-adhesive strip. Special finishes available upon request.
