INTELLO®
Intelligent High-Performance Vapor/Vapour Retarder
Optimum Protection for all Thermal Insulation Systems in Roofs, Walls, & Floors
INTELLO® high performance vapor/vapour retarder gives structural systems a previously unachievable degree of protection from structural damage, even under extreme external climatic conditions.
INTELLO® with humidity-variable permeability provides previously unachievable protection in comparsion to conventional vapor/vapour barriers such as PE-films.

Interior Insulation
- Vapor/vapour retarder with the world’s larges range of humidity-variable diffusion permeability at any climatic conditions
- Very low diffusion permeablity in wintertime and very high diffusion permeablity in summertime
- In wintertime, the low diffusion permeablity provides ideal protection for the building’s structure against moisturization, i.e. against mould growth and rot
- In summertime, the high diffusion permeablity facilitates rapid drying out of moisture out of the structure
- Translucent, easy to install
- Fully recyclable
- Ideal solution for constructions with high permeability to the exterior
- Ideal solution for constructions with lower permeability to the exterior e.g. flat roofs, green roofs, flexible metal sheeting, etc.*
- High performance against mould growth, which protects the health of the occupants
Maximum Security
INTELLO® high performance vapor/vapour retarder gives structural systems a previously unachievable degree of protection from structural damage even under extreme external climatic conditions.
Humidity-variable vapor/vapour retarder INTELLO® provides previously unachievable protection in comparisation to conventional vapor/vapour barriers such as PE-films.
The Difference between Conventional Technology and the new INTELLO®
To prevent structural damage, the usual approach is to concentrate on reducing moisture stress. However, structural systems cannot be fully protected from the effect of humidity or moisture. Planned moisture stress produced by moisture vapor/vapour diffusion is virtually never the cause of structural damage, the usual culprit being unanticipated moisture stress that cannot be entirely ruled out by building design.
To exclude the likelihood of structural damage and mould growth, it is advisable, apart from considering moisture stress, to concentrate on the drying capacity of a structural system. Systems with a high drying capacity and a simultaneous reduction in moisture stress, as provided by vapour membranes/retarders with a humidity-variable diffusion permeability, like INTELLO® are still very safely and reliably protected against structural damage even if subjected to unanticipated moisture stress.
Foreseeable or planned moisture stress:
- Diffusion processes
Unanticipated moisture stress:
- Heightened moisture in the building components used
- Design-induced transport of moisture (e.g. flank diffusion through adjoining masonry)
- Convection, i.e. air flow (leaks in the air barrier)
The numerous ways in which moisture can enter are a clear indication that, in everyday building practice, the possibility of moisture stress on a structural system can never be ruled out. When the object of the exercise is to build without likelihood of damage, the provision of increased drying reserves is a far more effective and reliable solution than any strict concentration on letting as little moisture as possible into the structural system.
