Product information "Ampatex DB 90 vapour control layer and airtight sealing – short roll with Ampacoll INT (30 linear metres / 37.5 m²)"

Ampatex DB 90 vapour control layer and airtight sealing – short roll with Ampacoll INT (30 linear metres / 37.5 m²)

Ampatex DB 90 is a high-quality, two-layer vapour control layer and airtight membrane for use in almost all rear-ventilated roof and wall constructions. It offers a high-performance alternative to conventional PE films and impresses with its high tear resistance, dimensional stability and particularly easy installation.

Manufactured from thermally bonded continuous fibres with an integrated PP filler layer (100% polypropylene), the membrane is entirely homogeneous, free from plasticisers and designed for long-term use in modern timber and drylining construction. Thanks to its translucent surface, it offers additional safety when blowing in cellulose or other blow-in insulation materials.

The membranes do not expand or contract, do not attract dust and feature a printed cutting guide for quick and precise installation. With an sD value of approx. 20 m, Ampatex DB 90 reliably ensures moisture protection and permanently effective airtight sealing of the building envelope.


Area of application


  • On the warm side of the thermal insulation in dry interior fit-out

  • Roof and wall constructions 

  • Particularly suitable for constructions with blow-in insulation

  • Universal standard vapour control layer for new builds and refurbishments

Installation instructions


Ampatex DB 90 is installed on the warm side of the thermal insulation. The printed, smooth side faces the room and serves as the adhesive surface. The membranes must overlap by at least 10 cm and be bonded airtight using the supplied Ampacoll INT.

  • Fixing in the overlap area: concealed with staples or nails

  • Carry out edge junctions using Ampacoll BK 530 or Ampacoll RA

  • Permanently seal penetrations (e.g. pipes, rafters, purlins) with Ampacoll BK 535 (50 mm)

  • Prime porous or dusty substrates with Ampacoll Primax

The final mechanical fixing of the membrane is achieved by the interior cladding.


Ampatex DB 90 stands for reliable airtight sealing, high installation reliability and long-lasting moisture protection – the professional solution for demanding roof and wall structures.
