The dome of the CUBEX is an inflatable dome measuring 5 or more meters in diameter. It is inflated by a three-speed fan that continuously blows air into its interior. To enter and exit, the highest blowing speed is used to compensate for air that is lost. Once the audience is inside, the fan’s speed is reduced to its lowest speed to maintain a quiet, continuous airflow that keeps the dome inflated and the interior comfortably ventilated.

The dome fabric is a blackout type and has a fire retardant treatment that meets the NFPA-701 standard. A FR (fire retardancy) certificate is furnished with each dome. Its complete opacity ensures optimum darkness and thus the best sky possible, regardless of the lighting outside the dome. Entrance to the dome is quick, comfortable and safe. The two meter high entrance is easily opened and closed with a doble-sided, easy to grasp zipper.

The exterior standard color of our domes is blue but domes could be custom decorated with space artwork painting as is shown in the just below image. Our company name and data are never visibly printed on our domes. 

The dome is remarkably lightweight. At only 22 Kg. (48 lbs) for the 5 meters one, it is the lightest one available for its size. It can be transported by one person with a minimum of effort.

Since the dome does not have a floor, emergency evacuation is instantaneously and safely achieved by simply lifting the dome over the audience’s heads and to one side, exposing the interior in seconds. This is the same procedure to take down the dome. Once folded, the dome fits neatly in the provided carry bag.

The below figure shows the 5 meters CUBEX dome measurements. The Cubex dome is made in a wide range of sizes, from 5 to 9 meters.
