PRODUCT DESCRIPTION
ISO-CONNECT VARIO XD is a humidity variable special foil for the inner and outer sealing of windows and facade connecting joints. The foil reacts to the different seasonal temperature gradients by variably adapting its sd-value,thus achieving a high drying effect in the joint all year round. It complies with the requirements of EnEV (energy saving regulations) concerning to the airtightness of the building envelope and the recommendations of the RAL quality assurance association for windows and doors in the “Installation guide”. The foil can be used under the window sill (eg. for External Wall Insulation systems) as the 2nd trough shaped sealing level.
Applications
ISO-CONNECT VARIO XD is excellently suited for the sealing of both internal and external window and door elements in metal, window and facade constructions. The fleece-covered special foil is available in different self-adhesive finishes for quick and proficient installation.
PRODUCT ADVANTAGES

** It is only possible to determine the variable sd-value with a dynamic calculation program (e.g. as indicated in the literature [10][10] in DIN 41083:2001-07). For the calculation according to the static method a fixed sd-value of 2,5 m can be used. |
Preparation
The bonding surfaces must be free of humidity, dust, stripping agents, oil, grease and other anti-adhesive substances. Pre-treat porous and absorbent surfaces with primer. Bond the window connection foil without tension with sufficient slack for movement between the frame and the building reveal. Unless using Finish F, we recommend ISO-TOP FLEX-ADHESIVE for this purpose. Apply enough adhesive to leave a caterpillar strip about 30 mm wide and at least 1 mm thick after the foil has been pressed in place. With the butyl self-adhesive version, pre-treat the surface with primer if necessary and then apply the butyl self- adhesive to the surface.
Use a roller to carefully press the strip in place. On areas which are to be plastered over, a full surface bonding caterpillar strip should be applied. A foil surface of max. 20 mm should be left unglued to allow for potential movement. Corners and overlaps in the foil must be bonded using ISO-TOP FLEX-ADHESIVE. Fully self-adhesive finish COMPLETE does not require any additional adhesion with our ISO-TOP FLEX ADHESIVE. It must be noted that only the fleece-covered side can be plastered over. The window connection foil bonded to the outside of the building must always be covered. As the 2nd level sealing, under a window sill, lay it in a trough shape with side going up the reveal wall, paying particular attention to the corners (possibly with preprepared corners) and stick with ISO-TOP FLEX-ADHESIVE. For detailed information about processing see the installation instructions.
