I. Installation steps
1. Install the membrane
Roll out the membrane parallel to the eave and use galvanised staples that are at least 10 mm (3/8") wide by 8 mm (5/16") long to fasten the membrane in the overlap area in a manner that protects against moisture entry. Install the membrane leaving an additional 4 cm (1 5/8") overlap at adjacent building components so that an airtight bond can be applied here subsequently.
2. Overlap the membranes
Allow for an overlap of approx. 10 cm (4") between the membranes. The marking that is printed onto the membrane will serve as a guide here.
3. Overlap: ‘connect’ adhesion
Stick the membrane overlaps using the integrated ‘connect’ self-adhesive strips; gradually stick these strips in place, ensuring that there are no folds or tension.
Position the sealing lip at the bottom of the membrane onto the marking that is printed onto the membrane underneath.
Rub the seals firmly with the pro clima PRESSFIX application tool to secure them. Ensure that there is sufficient resistance pressure.
4. Stick the overlap
Clean the subsurface (dry and free of dust, silicone and grease) and carry out an adhesion test, if necessary. Centre the TESCON VANA system adhesive tape on the overlap and gradually stick it in place, ensuring that there are no folds or tension. Rub firmly using the pro clima PRESSFIX application tool to secure the adhesive bond. Ensure that there is sufficient resistance pressure.
5a. Installation at ridge / hip
In the case of fully insulated cross sections, place membranes over the ridge/hip and attach in place using staples in the area of the counter batten. Overlap relative to the membrane underneath of approx. 10 cm (4").
5b. Installation at ridge / hip
Then tape in an airtight manner using the TESCON VANA system adhesive tape. Alternatively, stick a wide strip of TESCON VANA onto the ridge. Rub the tape firmly using the pro clima PRESSFIX to secure the adhesive bond. Ensure that there is sufficient resistance pressure.
6. Sealing at eaves
Position the membrane on the eave flashing or eave strip and stick in place using the integrated self-adhesive zone (for 'connect' membranes), double-sided DUPLEX adhesive tape or single-sided TESCON VANA system adhesive tape, ensuring that there are no folds or creases.
7. Sealing to rough or mineral subsurfaces
First create a smooth finish on rough wall caps. Clean the subsurface. Apply a line of ORCON F system adhesive with a thickness of at least 5 mm (3/16") (more in the case of rough subsurfaces, if necessary).
8. Penetrations
Penetrations and other installed components can be reliably sealed using pro clima system products. Ensure that seals are created with no folds, creases or tension.
Rub the seals firmly with the pro clima PRESSFIX application tool to secure them.
Ensure that there is sufficient resistance pressure.
9. Repairs
Any damage to open areas of the membrane should be taped using the TESCON VANA system adhesive tape, applied with no folds or creases. Rub the tape firmly using the pro clima PRESSFIX to secure the adhesive bond. Ensure that there is sufficient resistance pressure.
