AUTOTAK VAP is a self-adhering waterproofing membrane made of distilled bitumen modified with SBS (Styrene-Butadiene-Styrene) polymers, with an adhesive coating on the lower face.

Application is very simple and safe: once aligned the roll in place over a clean and primed substrate, by simply removing the silicone films from the underside and from the selvedge strips, AUTOTAK VAP will adhere in place without the need of a propane gas torch or a hot air machine. Head joints require the use of an approved mastic sealant (COPERGLUE JOINT bituminous adhesive is recommended).



 AUTOTAK VAP has two separate carriers: a reinforced glass carrier that provides very good dimensional stability, and a special aluminium that makes AUTOTAK VAP ideally suited for applications where a perfect vapour barrier is required.


Intended use according CE Mark Standards

  • AUTOTAK VAP  1,6 mm: self-adhesive waterproofing barrier against water vapour diffusion (EN 13970)





Available surface finishes

AUTOTAK VAP  - upper surface

Plastic HDPE film with 10 cm silicone release side overlap


Lower surface

Lower face is covered with a silicone release film, non-stick and removable, divided into two parts for easy placement and alignment of the rolls during the application.


Use & Application

Pitched roofs

AUTOTAK VAP is recommended for use as a self-adhering vapour barrier or vapour check layer for applications in presence of high relative humidity and/or low ventilation; it is normally positioned below the insulation layer but, as a rule and subject to the construction design, it must be installed in a position to prevent the insulation layers from becoming in contact with the sources of humidity and preserve in time the effectiveness of the insulation properties.

For correct installation refer to information provided by Copernit Technical Department.
