SOLITEX FRONTA HUMIDA
Breather membrane (WRB) for use behind ventilated pre-wall shells
Advantages
- In accordance with DIN 68800-2: for timber wall structures behind ventilated pre-wall shells
- Protects wall structures against moisture from the ventilation layer
- Protects the building component during the construction phase: very resistant to driving rain
- 3 months of outdoor exposure
Areas of application
For use as a slightly diffusion-inhibiting breather membrane (weather-resistive barrier, WRB) on mineral-fibre and wood-fibre insulating panels behind a ventilated masonry/brick exterior wall.
Planning and construction guidelines
Areas of application
SOLITEX FRONTA HUMIDA is a slightly diffusion-inhibiting breather membrane (WRB) for use on wood-fibre insulating panels behind ventilated pre-wall shells.
- Its diffusion resistance has been chosen in such a way that moisture can escape efficiently from the timber frame compartments to the outside.
- At the same time, the insulation is protected against reverse diffusion of moisture from the air layer behind the pre-wall shell.
High quality requirements
With its very high resistance to driving rain and extremely high tear resistance, SOLITEX FRONTA HUMIDA fulfils demanding requirements relating to protection of building structures during the construction phase and can be subjected to outdoor exposure for up to 3 months. Active diffusion transport through the monolithic polymer membrane ensures permanently dry building components.
No rear ventilation of the insulation layer is necessary
Rear ventilation of insulation materials is not required as a result of the high diffusion permeability of pro clima SOLITEX FRONTA HUMIDA. When used in combination with a suitable vapour check, SOLITEX FRONTA HUMIDA can be installed directly onto the thermal insulation, i.e. the insulation material can fill the full available depth.
Increased indoor humidity
These highly permeable membranes allow moisture to dry out of the structure to the outside more easily and more quickly. This is advantageous both during the construction phase and during normal use (if moisture contained in the indoor air penetrates into the structure by diffusion or convection).
As a rule, moisture that arises due to construction work should be able to escape the building structure 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 FRONTA HUMIDA membrane offers particularly good seal tightness against driving rain. The membrane can be installed onto the surface of insulation materials or boarding. A tent effect is reliably prevented by the monolithic functional film and the multi-layer structure. The term ‘tent effect’ describes the phenomenon whereby waterproof tent sheets allow large amounts of moisture into tents at points where they are in contact with inside objects.
