Vapour check and airtight layer with high sd value.

  • High stability and tear strength
  • Does not stretch or shrink
  • Translucent – substructure remains visible
  • Does not contain plasticisers

Double layer vapour check and airtight layer with high sd value for wood structures with impermeable layers on the outside, such as bonded thermal insulation façades in conjunction with moisture-tight insulation materials. Also suitable for internal
insulation in older masonry structures. Also suitable for cellulose insulation. Fleece underlay made of polypropylene (PP) with a special membrane made of polyolefin.

Ampatex Cento is both a vapour check and an air seal. All joints, gaps, overlaps, connections and openings must be  hermetically sealed. Surface damage must be sealed. In dry interiors, Ampatex Cento should be used on the warm side of  the heat-insulating layer, and in areas where there is an overlap it should be fastened with concealed staples or nails. The smooth, printed side faces into the room and this is the surface onto which the next product should be taped. When laying, make sure that the strips overlap by 10 cm. The overlaps should then be completely covered with the Ampacoll INT supplied. Ampacoll DT adhesive tape is useful where the underlying material cannot be nailed. Finally the lining on the inside is fixed in place. Ampacoll BK 530 or Ampacoll RA are used for edge connections. Porous or dusty surfaces should be pretreated with Ampacoll Primax. Penetrations such as ventilation pipes, conduits, purlins, rafters, etc. should be  permanently sealed with Ampacoll BK 535, 50 mm wide. With porous, dusty or rough surfaces, a pretreatment of Ampacoll Primax is also required.
