Latex is the material that suffers. Ultraviolet light oxidises natural rubber, so the surface turns matte and chalky within a couple of hours in direct Dubai sun, and heat expands the gas inside at the same time. A balloon that was inflated to full size indoors is then stretched past what the weakened wall can hold, and it bursts.
Foil reflects a good part of the radiation and does not oxidise in the same way, so foil shapes and numbers remain the most reliable choice outdoors. Bubble balloons also hold up well, and both keep their appearance when latex has already gone dull.
Technique matters as much as material. Outdoor balloons are deliberately inflated slightly under full size so there is room for the gas to expand, dark shades absorb noticeably more heat than pastels and white, shade from a tent or an awning extends life considerably, and installing close to the start of the event rather than hours ahead avoids the worst of the midday exposure.
- Foil and bubble balloons handle sun and heat far better than latex
- Underinflate outdoor balloons slightly to leave room for expansion
- Pale shades absorb less heat than dark ones and last longer
- Use shade from tents, awnings or trees wherever possible
- Install close to the event time rather than hours in advance
Tents and shade structures can be hired through our rental services.
