INTELLO X
All-round hydrosafe® high-performance vapour check
Advantages
- Excellent protection against mould and moisture damage to structures thanks to humidity-variable diffusion resistance
- Easier handling: can be used with insulation installed between rafters/framework, with external insulation and – in the case of refurbishment from the outside – between two layers of mineral wool insulation
- Protects building structures against weathering during the construction phase for roof pitches of 10° (2.1:12) and higher
- Protected winter building sites thanks to hydrosafe® behaviour
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
Areas of application
Vapour check (alternate terms: vapour control or retarder) membrane for use on the inside of insulation installed between rafters or wall framework, in combination with fibrous insulation mats and boards. Can be installed directly on top of sheathing for use underneath exterior insulation, also in combination with blown-in insulation materials.
This membrane can be permanently exposed to diffuse UV light – e.g. in areas without inner cladding.
In the case of refurbishment from the outside and installation between two layers of insulation, the choice of insulation materials for the two layers is limited to mineral or rock wool. The thickness of the external mineral wool insulation needs to be calculated on a project-specific basis; please contact Technical Support at pro clima in Germany for assistance.
This membrane can be used on building components that are diffusion-open to the outside or are diffusion-tight, e.g. pitched, flat or green roofs, after appropriate design calculations have been carried out.

General conditions
pro clima INTELLO X is to be installed with the printed side facing the installation technician. The membrane is to be installed horizontally (parallel to the eave) in a taut manner.
Airtight seals can only be achieved on vapour checks 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 avoid condensation formation, the thermal insulation should be installed immediately after the airtight installation of INTELLO X. This applies particularly to work carried out in winter.
Fastening
Overlap the membranes by at least 10 cm (4"). Use fastening staples that are at least 10 mm (3/8") wide by 8 mm (5/16") long to attach the membranes. The membranes can only be fastened in a protected manner in the overlap area. The maximum distance between fasteners is 10 to 15 cm (4" - 6"). Fasteners may not be applied in areas where water runs off in a collected manner (e.g. in roof valleys).
If exposure to the elements is planned, it is recommended to provide additional mechanical support for the membranes (e.g. with counter battens). TESCON NAIDECK mono adheres to counter battens, seals nail holes and improves the level of rain protection.
