Areas of application
Vapor retarder (alternate terms: vapor check or control) membrane for use on roofs, walls, ceilings and floors on structures that are open or closed to diffusion on the exterior, e.g. flat/pitched roofs and green roofs, after appropriate design calculations have been carried out.
Installation steps
1. Install the membranes
Roll out the membrane and fasten it using galvanized staples that are at least 3/8" (10 mm) wide by 5/16" (8 mm) long at intervals of 4" to 6" (10-15 cm) or, if blown-in insulation is to be installed, 2" to 4" (5-10 cm). Install the membrane leaving an additional 1 5/8" (4 cm) 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. 4" (10 cm) 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
Center 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. Center 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 CONTEGA HF adhesive sealant of at least d = 3/16" (5 mm), 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 CONTEGA 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 CONTEGA HF 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 vapor retarder 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. Center 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 CONTEGA HF adhesive sealant of at least d = 3/16" (5 mm), or more in the case of very rough subsurfaces if necessary. As an alternative, a roll of CONTEGA MULTIBOND adhesive sealant 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 CONTEGA HF 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 center, create corner shapes and then stick in place.
13. Sealing around pipes and cables
Place a KAFLEX or ROFLEX sealing gasket over the cable or pipe and stick to INTELLO. The cable gaskets are self-adhesive. Stick the pipe gaskets 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 ≤ 1' 8"; 50 cm) 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.
General conditions
Where possible, INTELLO should be installed in such a way that adhesion can be carried out using single-sided adhesive tape on the smooth (printed) side of the sheeting. It should be installed taut and without slack either in parallel with or perpendicular to the supporting structure, e.g. the rafters. In the case of horizontal installation (perpendicular to the supporting structure), the separation distance of the supporting structure is limited to a maximum of 3' (100 cm). After installation, perpendicular battens on the inside at a separation distance of a maximum of 1' 8" (50 cm) must be fitted to carry the weight of the insulation material.
If regular tensile loads on adhesive tape bonds are to be expected – for example, due to the weight of the insulation material – when using mat or panel-shaped insulation materials, an additional supporting batten should be fitted over the overlap sealing. When attaching the membranes in the case of mat or panel-shaped insulation materials, a maximum separation distance of 4" to 6" (10 to 15 cm) applies for the fastening staples, which must be at least 3/8" (10 mm) wide by 5/16" (8 mm) long. The overlaps between the membrane strips must be approx. 3" to 4" (8 to 10 cm).
Airtight seals can only be achieved on vapor retarder (alternate terms: vapor check or control) membranes that have been fitted with no folds or creases. Ventilate regularly and systematically to prevent build-up of excessive humidity (e.g. during the construction phase). Occasional, intermittent ventilation is not sufficient to remove large quantities of moisture due to construction work from a building; use a dryer if necessary.
To prevent condensation formation, INTELLO should be sealed and taped in an airtight manner immediately after the installation of the thermal insulation. This particularly applies when working in winter.
