Planning notes SOLITEX MENTO
In order to achieve the best possible results when installing the roof lining and sarking membranes of the pro clima SOLITEX MENTO family, please consider the following points when planning and implementing your project.
No rear ventilation is necessary
No rear ventilation is necessary Thanks to the high diffusion permeability of pro clima SOLITEX, rear ventilation of insulation is not required. The membrane can be applied directly onto the thermal insulation in all cases, i.e. the insulation thickness can be equal to the full height of the rafters. In the case of non-insulated attics, it is advantageous to provide hip ridge ventilation in order to ventilate the attic space. Complicated and often ineffective aeration and ventilation details at the eaves, ridge, valley, hip and additional roof features are thus unnecessary.
Maximum diffusion permeability
Moisture can dry out of the structure to the
outside more easily and more quickly. This is
advantageous both during the construction phase
(when construction timber may be moist) and
during normal use (when moisture from indoor
air penetrates into the structure by diffusion or
As a rule, moisture due to construction work should be able to escape the building quickly by ventilation through open windows. Dryers can help to speed up the drying process in wintertime.
This helps to avoid permanently high levels of relative humidity.
No tent effect
The pore-free SOLITEX membrane offers particularly good protection against driving rain. Membranes in the SOLITEX MENTO family can be installed directly on top of insulation materials or roof decking. A tent effect is reliably prevented by the monolithic membrane and the multi-layer structure. The term ‘tent effect’ refers to the phenomenon that watertight tent sheets cause the entry of large amounts of moisture into building components at their points of contact.
In cases where there were previously no underlays,
these can be retrofitted using SOLITEX
underlay and sarking membranes. SOLITEX membranes
provide optimal protection for the insulation
structure thanks to the new technology of
pore-free membranes. They are highly permeable
and, at the same time, particularly resistant to
driving rain, tear-resistant and insensitive to
SOLITEX MENTO 1000, 3000 and 5000 can be combined with all mat-shaped and panel-shaped insulation materials. For blown-in insulation, the use of reinforced SOLITEX MENTO PLUS is recommended.
Rainproof roof lining
The SOLITEX MENTO family fulfils the requirements of the ZVDH (Zentralverband des Deutschen Dachdeckerhandwerks - National Association of the German Roofing Trade) as a result of their exceptional high watertightness and high strength. It is suitable as an additional rain protection measure:
- as a roof lining membrane of classes 3, 4 and 5
- as a roof sarking membrane of classes 3, 4 and 6
The membranes can be used as a temporary cover.
Classification of the membranes in classes according to the ZVDH instructions
|Name according to ZVDH||pro clima SOLITEX (1)||Adhesive and tape, nail sealing tape||Class|
|Seam and perforation-secure roof lining||pro clima SOLITEX MENTO 1000 (or the respective connect version) with pro clima system accessories||Adhesion in accordance with pro clima bonding agents and with TESCON NAIDECK||3|
|Bonded roof lining||as before||Adhesion in accordance with pro clima bonding agents, without nail sealing tape||4|
|Overlapped roof lining||pro clima SOLITEX MENTO 1000||Loosely overlapping||5|
|Seam and perforation-secure roof sarking||Taut or free-hanging pro clima SOLITEX MENTO 1000 (or the respective connect version) with pro clima system accessories||Adhesion in accordance with pro clima bonding agents and with TESCON NAIDECK||3 (2)|
|Seam-secured roof sarking||as before||Adhesion in accordance with pro clima bonding agents, without nail sealing tape||4|
|Sarking||Taut or free-handing pro clima SOLITEX MENTO 1000||Loosely overlapping||6|
(1) pro clima SOLITEX MENTO membranes are always laid beneath the counter batten, the counter batten is not integrated.
(2) The requirement for roof sarking membranes is USB-A, which pro clima SOLITEX MENTO membranes fulfil.
