altimeter basicSmooth-running venetian blinds at any time

Each and every IG unit is prepared in the production in such a manner that there is a wide enough gap between the panes so that the blinds don’t touch. Additional after-treatment is not required!


  • Highest precision by high resolution pressure sensors 
  • Safe operation because of intuitive construction 

The HELANTEC valve is a small but important detail. Only with this valve can it be ensured that the executed pressure balance remains intact and that your assured characteristic of the IG unit does not change.
