Airtightness systems and moisture management systems

The highest standards for energy efficiency, lifetime performance, indoor air quality and thermal comfort all year round can only be achieved if the building shell is made perfectly airtight and protected against moisture.
With the Vario System, ISOVER has the ideal range of products to meet this challenge. They prevent uncontrolled airflows, and help you to make uncomfortable draughts, expensive heat loss and damage caused by mould or other fungi, a thing of the past.

The Vario smart membrane

The VARIO membrane is an airtightness membrane that helps regulate moisture in the construction: it adapts to the climate conditions in order to protect the building fabrics:

in winter, the membrane blocks the moisture generated inside the rooms and prevents it from penetrating into building’s structure.
in summer, it allows the moisture to escape outside the building structure.

Vario XtraSafe, the latest innovation from ISOVER, improves the airtightness installation’s safety and it offers the best moisture management in most critical climate condition.

When combined with high-performance mineral wool insulation and installed using the range of specially developed accessories, the VARIO membrane creates a perfectly airtight envelope that guarantees the building’s high energy performance.
