Light, full-surface adhesive, permeable airtightness and weathering-protection membrane

Advantages

  • Protects the structure: Diffusion-permeable and maximum protection against driving rain
  • 4 weeks of outdoor exposure to protect floors during construction
  • Keeps building components dry by means of a pore-free moisture-active functional membrane
  • Easy and reliable installation thanks to its split release film - sticks immediately to subsurfaces with sufficient load-bearing capacity
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • 3 months of outdoor exposure for inclined roofs and walls

Areas of Application

Steep roofs and walls

allows airtightness to be achieved on wood-based products and mineral subsurfaces – e.g. on the exterior side of unplastered (fair-faced) masonry or concrete components with joints. For roofs, it also fulfils the requirements of the Central Association of the German Roofing Trade (ZVDH) for an underlay and for temporary coverings for the specified time period.

Temporary protection for ceilings/floors during construction

thanks to its full-surface adhesion, this product provides temporary protection for intermediate ceilings and floors on multi-storey CLT (cross-laminated timber) or wooden-frame buildings during the construction period.

Planning and construction guidelines

Areas of application

The pro clima SOLITEX ADHERO 1000 and 3000 self-adhesive and airtight weathering-protection membranes can be used:

  • for temporary protection of wall elements and intermediate ceilings during construction on multi-storey timber-element buildings,
  • to achieve airtightness on the interior and exterior of wood-based products and mineral subsurfaces,
  • on the exterior side of wooden-frame walls behind ventilated pre-wall shells,
  • as a nail-sealing pre-underlay on roof decking and suitable wood-based panels (e.g. cement-bonded particleboard in accordance with DIN EN 634-1) underneath slate coverings.

Use as temporary protection on timber element structures during construction

SOLITEX ADHERO membranes can be used as temporary protection at ceilings and floors on multi-storey timber construction projects.
Run-offs that remove water from the intermediate ceiling and/or building are to be provided so that rainwater does not accumulate on the membrane.
Full-surface adhesion prevents water from spreading under the membrane if the membrane should be damaged during the course of construction.
At element joints and/or joints with wood-based panels, at least 15 cm (6") of SOLITEX ADHERO is to be guided onto the adjacent element/wood-based panel.
Timber (material) surfaces that may have become damp can quickly dry out again thanks to the low diffusion resistance.

Use to achieve airtightness of walls on timber structures

The pro clima SOLITEX ADHERO system can be used to achieve airtightness on timber-element walls (wooden-frame and CLT elements) on the inside and outside.
In the case of membranes applied on the exterior in particular, it should be ensured that the airtightness layer of the walls is bonded to the airtightness layers of the roof surfaces.
For installation on the exterior, these products additionally provide weathering protection during the construction phase.
Full-surface adhesion with the relevant subsurface also ensures that seepage behind the membranes cannot occur.

Use to achieve airtightness of walls on masonry and concrete structures

Unplastered masonry and concrete walls, e.g. made from pre-fabricated components, are regarded as not being airtight due to their joints.
SOLITEX ADHERO 1000 and 3000 can be stuck directly onto the exterior of stable mineral subsurfaces.
Adjacent airtight building components also have to be stuck to one of these membranes in the area around joints to ensure the airtightness of the surface.

Use for the protection of timber structures behind pre-wall shells

After driving rain has fallen on a pre-wall shell (e.g. faced masonry), heating up can result in a microclimate with increased relative air humidities.
To prevent this moisture entering into the component, DIN 68800-2 recommends that a membrane with a slightly increased diffusion resistance should be fitted on the exterior of wooden-frame construction elements.
The SOLITEX ADHERO membranes have an sd value of at least 0.25 m (g value: > 1.25 MN·s/g or < 13 US perms) for this purpose, which protects the component from the outside and also allows for drying out.
These membranes can be stuck directly onto stable subsurfaces.
Pre-treatment with TESCON PRIMER RP may improve adhesion to subsurfaces.

Use as a nail-sealing overlay underneath slate coverings

Thanks to their full-surface adhesion, both SOLITEX ADHERO membranes seal nail holes in suitable wood-based panels (e.g. cement-bonded particleboard in accordance with DIN EN 634-1) or solid-wood boarding, thus ensuring better protection for building components.
It should be taken into account here that the sealing function is ensured when nails are hammered into the timber or timber material subsurface.
This protection is not guaranteed in the case of nail holes at joints.

Moisture in materials due to construction work

The low sd (g) values (or high perms) of SOLITEX ADHERO allow moisture to dry out of the construction materials that are used.
If this drying takes place too quickly (e.g. due to heating), bubbles may form behind the membranes due to the water vapour that results.
The performance of the membrane as an airtight layer and as weather protection is not compromised by this, provided that these bubbles do not open up membrane overlaps.

Quality assurance

In contrast with the case of membrane overlaps on the interior, quality checking using the differential pressure procedure (e.g. using BlowerDoor) is only possible with overpressure for membrane installation on the exterior.
In this case, fog must be generated in the interior of the building using a fog machine.
The airtightness of detail features can then be checked on the exterior.

No tent effect

Pore-free SOLITEX ADHERO membranes offer particularly good seal tightness against driving rain. These membranes can be applied over the surface of insulation materials or roof decking.
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.
