Wall lining membrane for open-jointed cladding, gap width up to 50 mm (2")

connect variant with self-adhesive zones


  • Extremely robust and UV-stable: UV ageing test carried out with 10,000 h instead of 5,000 h
  • Dry building components: pore-free TEEE functional membrane actively transports moisture to the outside
  • Ensures reliable building components: permeable, extremely high tear-resistance, windproof, rainproof and waterproof
  • Not visible behind open-jointed cladding: black fleece with identification marking in the overlap area
  • 6 months of outdoor exposure

Areas of application

For use as a wall lining membrane behind closed and open facades (open-jointed cladding up to a gap width of 50 mm (2") and 40% open total area). Installation on boarding, wood-based panels and all mat or panel-shaped thermal insulation materials.

Planning and construction guidelines

Area of application

Its robust construction makes SOLITEX FRONTA PENTA an ideal wall lining membrane.

  • It can be laid as an exterior sealing membrane directly on the posts of the framework or insulation and as a wall lining membrane on boarding made from solid wood or wood-based panels.
  • It prevents cold, outside air flowing through rear-ventilated constructions near the surface and ensures the optimum effectiveness of the thermal insulation.

Driving rain and open jointed façades

As a result of its excellent resistance to driving rain and its extremely high tear resistance, SOLITEX FRONTA PENTA meets high requirements on the protection of the construction during the building phase and is weather resistant for up to 6 months before the final cladding is installed.

Active diffusion transport via the monolithic polymer membrane insures that structural components stay dry.

The membrane can be used behind gap decking with a max. gap of 50 mm (2") or with up to a maximum of 40% of the open total area.
The rear ventilation layer should have a thickness of at least 20 mm (.8").

No rear ventilation of the insulating layer is necessary

The high diffusion capacity of pro clima SOLITEX FRONTA PENTA means that it is not necessary to rear-ventilate thermal insulation.
Pro clima SOLITEX membranes can in all cases be laid directly on the thermal insulation, which means that the thermal insulation can fill the entire depth of the structure.

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 convection).
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 FRONTA PENTA membrane offers a particularly high tightness to driving rain.
The membrane can be laid to cover the entire surface of insulation materials or linings.
As a result of the functional film being monolithic and having a multi-layer construction, a tent effect is reliably prevented.
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.
