Ballons Hélium : Guide Complet pour un Événement Réussi

Are you planning a wedding, a birthday, or a corporate event and want to create a memorable decoration? Helium balloons are one of the most visually impactful—and versatile—elements to transform any space. This guide answers all your questions.

How long do helium balloons float?

Float time depends on the type of balloon:

  • Latex balloons (30 cm): 8 to 12 hours indoors, less outdoors (heat, wind)
  • Hi-Float treated latex balloons: up to 24–48 hours
  • Mylar / foil balloons: 3 to 5 days, sometimes more than a week

💡 Pro Tip: For a wedding or daytime event, inflate your latex balloons the morning of. For an installation the day before, you must choose Mylar balloons or Hi-Float treated latex.
