Product information "Ampatex Variano 3 extra, including 60 linear metres of Ampacoll INT – moisture-variable, grid-reinforced vapour control layer (75 m²)"
Applications and benefits:
Maximum flexibility: Perfectly suited to flat roofs in timber construction as well as for the renovation of pitched roofs with a watertight outer membrane.
Roof renovation from the outside: Thanks to its robust structure, it is ideally suited for installation from the outside during renovation projects.
Safety during the structural shell phase: Offers special protection during the winter construction phase, when ambient humidity is often a critical factor.
Outstanding workability: The membrane is characterised by excellent adhesion and, thanks to its mesh reinforcement, is particularly dimensionally stable.

Installation tips
Installation: Ampatex Variano 3 extra is installed on the warm side of the thermal insulation layer. It is fixed to the substructure using staples in dry interior fit-out applications. Please note that moisture-variable materials may react to significant fluctuations in relative humidity – therefore, incorporate relief loops into your design and take shrinkage and expansion behaviour into account.
Bonding and sealing:
Overlaps: The membranes must overlap by at least 10 cm. These joints must be sealed airtight using Ampacoll INT system adhesive tape.
Edge junctions: Use Ampacoll BK 530 or the Ampacoll RA connection adhesive for connections to adjacent building elements.
Substrate preparation: For dusty or porous substrates, a primer coat of Ampacoll Primax is essential.
Sealing of penetrations: Pipes and cables should be permanently sealed using Ampacoll BK 535 or special Ampacoll Elektro / Install sleeves.
