Benefits
Heavy duty 4-layer reinforced vapor open subroof- and rainscreen membrane that is a WRB. it can
be used as blown-in insulation mesh, without the need for exterior sheathing (which can be a vapor
retarder) - allowing you to design/build a wall that is truly vapor open at the exterior. SOLITEX MENTO PLUSAirtight weather resistant
barrier (WRB) suitable for
dense pack insulation

follow the sOliteX MentO plUs application videos and pDf guides available on the sOliteX MentO
plus product page at foursevenfive.com.
for all connections and overlaps use system components of pro clima’s intelligent Airtight system. Use
tescOn VAnA for overlaps, tescOn pROfil for corner connections, cOnteGA Hf to adhere to rough
or uneven substrates & concrete connections, ROfleX for pipes penetrations, KAfleX gaskets for wire
penetrations, etc. for a full introduction to airsealing with pro clima products, follow details found in 475’s
free downloadable ebooks.
sOliteX MentO plUs can be used as a weather resistive barrier and exterior airtight membrane on
walls and roofs. for interior airtightness and vapor control, use intellO plUs vapor-variable, reinforced
membrane. the pro clima intelligent Airtight system provides complete protection against moisture-
induced failures in structurally challenging constructions such as diffusion-resistant flat/pitched roofs and
for walls or roof with vapor retarding exterior sheathing (OsB or plywood).
GeneRAl cOnDitiOns
pro clima sOliteX MentO plUs should be laid with the printed side facing the installer. it can be
laid perpendicular to the sub-structure or parallel along it (such as along the rafters). Membrane should
be applied taut and without sags or creases. the maximum on center spacing of the structure behind
sOliteX MentO plUs is 40”/100 cm. After membrane is applied, battens should be installed through
the sOliteX MentO plUs into the structure to support the weight of the blown insulation. the battens
should be less then 20” on center (50 cm).
if long term tensile forces on the taped overlaps are expected by dense packed insulation’s weight, an
additional supporting batten should be placed on each of those overlaps. Alternatively, the taped overlap
can be reinforced with tescOn VAnA tape applied at right angles to the overlap every 12”/30 cm.
please note: Watertight and Airtight seals can only be achieved on vapor control membranes that have
been laid
without folds or creases.
Additionally for blown-in insulation: Benefit of applying membrane parallel to substructure when installing
dense packed insulation afterwards, is that all overlaps are mechanically fastented and secured to
structural elements.
Above >14° (3:12) the sOliteX MentO membrane can be used as temporary roofing, with overlaps
taped and sealed.
Roof pitches below <14° (3:12) should be protected with additional means and methods (eg tarps) to
protect the construction from weather/rain exposure.
