Designed specifically for spherical projections as the basis and hub in touring situations. The curvature of the spherical dome, the completely opaque material, the comfortable entrance for visitors and the blocking of exterior light, together with the extraordinary ease at which it can be assembled, dismantled and transported are its most important characteristics. The planetariums have developed over time in many respects due to suggestions from our clients. Together with our collaborators we have done research into what is the most appropriate material to use in order to guarantee opacity, even when outside in the middle of the day, combining this information with the fact that the raw materials need to be sufficiently light, so that one person can assemble, dismantle and transport it alone. This inflatable should be able to receive thousands of people during its life span, many of whom would be young people, meaning that as well as the above mentioned characteristics, the components must also have a very high resistance. Some of our planetariums have had more than 40,000 students pass through them over  a period of 5 years, and still continue receiving people.
The material used for these coverings means that more than one exterior decoration can be used on its entire surface.
