  • Vapor slowing
    In connection with all diffusion-open DELTA® roofing membranes, DELTA®-LUXX offers optimal protection for roof structures, and it creates a high living comfort.
  • Airtight.
    When properly installed with the DELTA® system components, the vapor barrier prevents convective air currents from inside to outside.
  • Energy-saving
    Contributes to compliance with the airtightness of residential buildings required by the german EnEV.


DELTA®-LUXX may be laid in parallel to or crosswise the rafters. The printed and coated side must always face the processor. For the fastening, tackle clips or broad-headed pins can be used.

In the overlapping area, the membrane is glued with  DELTA®-MULTI-BAND. On smooth surfaces - for example on gable walls, purlins, chimneys, etc. - DELTA®-LUXX is connected airtight with the cartridge adhesive DELTA®-TIXX or DELTA®-TIXX VDR. On rough surfaces, the connection is made with DELTA®-LIQUIXX or the DELTA®-KOM-BAND. Corners or cables can be sealed with DELTA®-FLEXX BAND FG 80 / 150 oder DELTA®-FLEXX BAND F 100.
