Application Guide SOLITEX MENTO
So that pro clima SOLITEX MENTO can reliably protect the thermal insulation against the elements, it needs to be correctly installed. Find out what you need to consider during the installation process here.

General information on sticking the membranes
pro clima adhesive tapes for exterior bonding
have very good adhesion behaviour on:
- Subsurfaces that are dry, smooth and free of
dust, bitumen and grease
- Smooth surfaces such as wood-based panels
(chipboard, OSB panels, plywood)
- Planed and painted wood
- Plastic, glass, metal, and
- PE, PA, PP and aluminium sheeting (surface
tension > 40 dyn)
- Smooth mineral subsurfaces (e.g. plaster or
concrete; pre-treated with TESCON PRIMER RP)
- Wood fibre underlay panels (pre-treated with
TESCON PRIMER RP)
Adhesion to frozen surfaces is not possible. Subsurfaces must be suitable for permanent bonding. The best results in terms of structural stability are obtained on high-quality subsurfaces. To ensure optimal bonding, the tape must be rubbed into place carefully. A hard subsurface (such as timber, solid thermal insulation materials) is advantageous here. No permanent tensile or shear stresses may act on bonds implemented using adhesive tape. It is your responsibility to check the suitability of the subsurface. Adhesion tests may be advisable.
Surface defects can be sealed with SOLITEX membranes and the system adhesive tapes. The repair patch on the roofing membrane should then be positioned underneath the overlap of the next continuous roofing membrane above the defect and should be joined in a waterproof manner.
SOLITEX MENTO membranes should be laid with the printed side facing the installer. The membranes are to be installed as an underlay or sarking membrane horizontally (parallel to the eave) in a taut manner with no sagging.
When using as a sarking membrane the spacing between the rafters is restricted to 100 cm.
The membrane must not be secured in areas where water collectively drains off (e.g. in grooves).
In the case of uninsulated, undeveloped attic floors, ridge ventilation should be provided. For this purpose, the SOLITEX membrane should finish 5 cm before the ridge. In addition, the undeveloped attic floor should be provided with permanent ventilation devices.
To protect the construction during the building phase, as specified by ZVDH (Zentralverband des Deutschen Dachdeckerhandwerks - National Association of the German Roofing Trade), SOLITEX MENTO roof lining membranes and sarking membranes can be used as a temporary roof cover for up to 6 months. In this case the roof pitch must be at least 14°. The system components TESCON NAIDECK nail sealing tape, ORCON F joint adhesive and TESCON VANA for sticking overlaps or joints must be used.
The connect versions have two self-adhesive zones for secure exterior sealing.
The standards and guidelines of the German roofing trade association must be observed during installation and sealing.
According to the technical regulations of the roofing trade association, they are suitable as a sarking membrane for covering a tiled roof with simple overlapping as an additional protective measure against rain. When using as a roof lining membrane with simple overlapping on a timber shell, the SOLITEX MENTO membranes are also suitable at elevated requirements as an additional protective measure against rain.
