Installation steps
1. Install the membranes
Roll out the membrane and fasten it using galvanised staples that are at least 10 mm (3/8") wide by 8 mm (5/16") long at intervals of 10-15 cm (4" to 6") or, if blown-in insulation is to be installed, 5-10 cm (2" to 4"). 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. Fasten to stud wall frame members
Fastening of membranes to metal frame members on stud wall and ceiling structures using pro clima DUPLEX. Stick the membrane, ensuring that there are no folds or tension. Rub using the PRESSFIX application tool to secure.
3. 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.
4. Clean the subsurface
Clean the subsurface (dry and free of dust, silicone and grease) before taping; carry out an adhesion test, if necessary.
5a. Tape the overlaps
Centre the TESCON VANA system adhesive tape on the overlap and gradually stick it in place, ensuring that there are no folds or tension.
5b. Rub the adhesive joint firmly
Rub the tape firmly using the pro clima PRESSFIX to secure the adhesive bond. Ensure that there is sufficient resistance pressure.
6. Sealing to smooth, non-mineral subsurfaces …
… (e.g. knee walls made of wood-based panels) should also be implemented using TESCON VANA system adhesive tape. Centre the tape and gradually stick it in place, ensuring that there are no folds or tension. Rub the tape firmly using the pro clima PRESSFIX to secure the adhesive bond.
7. Sealing to rough or mineral subsurfaces
Clean the subsurface. Apply a line of ORCON F system adhesive of at least d = 5 mm (3/16"), or more in the case of very rough subsurfaces if necessary. Place INTELLO onto the adhesive bed, leaving slack to allow for expansion. Do not press the adhesive completely flat.
8a. Alternative: Sealing to mineral subsurfaces
Position ORCON MULTIBOND on the subsurface, roll it out and gradually stick it to the subsurface. Gradually remove the release film.
8b. Sticking the membrane / Rubbing the joint firmly
Apply the membrane onto the adhesive strip, leaving slack for expansion so as to allow for relative motion between components. Rub firmly to secure the adhesive bond using the pro clima PRESSFIX. Ensure that there is sufficient resistance pressure.
9. Sealing to unplastered subsurfaces
Stick the CONTEGA PV plaster-sealing tape onto INTELLO using self-adhesive strips. Ensure the tape remains in place by using ORCON F at discrete points. First plaster behind the tape, then apply the tape to the wet plasterwork and plaster over it fully.
10. Masonry gable end wall, creating an airtight joint
Put the vapour check in place. Leave slack for expansion so as to allow for relative motion between components. Remove all release films from CONTEGA SOLIDO SL or CONTEGA SOLIDO IQ. Centre the tape and gradually stick it in place. Rub the tape firmly using the pro clima PRESSFIX to secure the adhesive bond.
To achieve airtightness, plaster over the masonry and sealing tape.
11a. Sealing to roughly sawn timber
Clean the subsurface. Apply a line of ORCON F system adhesive of at least d = 5 mm (3/16"), or more in the case of very rough subsurfaces if necessary. As an alternative, a roll of ORCON MULTIBOND joint adhesive can be used.
11b. Sealing to roughly sawn timber
Place INTELLO onto the adhesive bed, leaving slack to allow for expansion. Do not press the adhesive completely flat.
12a. Sealing to plastered chimney (insulated or double-shelled)
Seal INTELLO using ORCON F as shown in Figure 7.
12b. Sealing to plastered chimney (insulated or double-shelled)
Then cut into short pieces of TESCON VANA as far as the centre, create corner shapes and then stick in place.
13. Sealing around pipes and cables
Place a KAFLEX or ROFLEX sealing grommet over the cable or pipe and stick to INTELLO. The cable grommets are self-adhesive. Stick the pipe grommets to the membrane using TESCON VANA.
14. Corner sealing
Guide TESCON PROFECT pre-folded corner sealing tape into the corner while the release film is still in place and stick the first independent adhesive strip. Then remove the release film and stick the second independent adhesive strip.
15. Battens, interior cladding
Install battens (e ≤ 50 cm; 1' 8") to bear the weight of the insulation, and install interior cladding to provide protection against UV light and other damage.
16. Quality assurance
It is recommended that airtightness should be checked using a blower door test.
