Medium-weight roof underlay with self-adhesive zones

SOLITEX MENTO 3000 connect

Advantages

  • Flexible planning of construction schedules thanks to 4 months of outdoor exposure
  • Ensures reliable building components: highly diffusion-open and maximum protection against driving rain
  • Dry building components: pore-free TEEE functional membrane actively transports moisture to the outside
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • Reliable during the construction phase: suitable for temporary coverings during construction work
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive zones along the membrane strips

Areas of Application

For use as permeable roof underlay on roof decking, MDF and wood fibre underlay panels, and on all mat or panel-shaped thermal insulation materials.

General conditions

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 1 m (3 ft).
pro clima’s Engineering Hotline or your local pro clima partner will be glad to provide information on how to proceed in the case of larger spacings.

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 (2") before the ridge. In addition, the undeveloped attic floor should be provided with permanent ventilation devices. The membrane should be protected against the long-term effect of UV (e.g. by blocking the entrance of light through the windows).

To protect the construction during the building SOLITEX MENTO 3000 can be used as a temporary roof cover for up to 4 months (the recommendations for specific locations may differ). 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 applicable national regulations must be taken into account when installing and sticking pro clima underlay membranes.

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.

SOLITEX MENTO® system - Retrofitting underlay from the inside

In cases where there is no underlay present, underlay can be retrofitted from the inside using one of the SOLITEX roof underlays.
SOLITEX membranes are equipped with a monolithic, pore-free functional membrane.
As a result, they are watertight against water from the outside and can actively transport moisture from the building structure into the open at the same time.
This ensures optimal protection for the insulation structure.
If blown-in insulation materials are used, use of the reinforced product variants SOLITEX MENTO PLUS or SOLITEX MENTO ULTRA is recommended.

Advantages

  • Ensures reliable building components: highly diffusion-open and maximum protection against driving rain
  • Dry building components: pore-free TEEE functional membrane actively transports moisture to the outside
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • SOLITEX MENTO PLUS / ULTRA: extremely robust thanks to reinforcement: suitable for blown-in insulation materials

Reliable system for installation from the inside

Roof structures without underlay and thus without a counter-batten plane are often encountered on existing buildings.
If insulation is to be fitted on these structures, it is recommended to first retrofit an exterior windtightness layer to improve the reliability of the structure.
This measure is recommended for a max. period of 5 years.
The roof pitch of the roof tiles must not be less than the standard roof pitch.
The roof pitch must be at least 20°.
Installation is carried out from the inside, proceeding in turn from one space between rafters to the next.
Battens at the corners of the rafters/tile battens allows for the necessary ventilation for the roof covering.
A ‘protruding lath’ in the middle of the space between rafters results in a valley in the SOLITEX membrane.
In this way, any water that has entered can be drained off to the middle of the area between the rafters (away from the rafters) and towards the eaves.
Attach the SOLITEX membrane to the rafters using battens or DASATOP FIX.
The membranes must be overlapped in a waterproof manner and must drain reliably into the open.
