The Go-Dome™ Airlock Door System can be left open during presentations. Its tubes come together to close and a Velcro strap is provided to indicate that a show is in progress. A second Velcro strap on the inside lets the operator close the door. Inside, the door also has a zipper and a Velcro latched flap that completely covers the zipper – producing a smooth projection surface. With the zipper open, visitors can leave during the presentation without requiring assistance from the operator. Visitors also feel much less enclosed and claustrophobic with an airlock door than with a dome that has an entrance tube or simple zipper.

The Airlock door is six feet tall, allowing audiences to walk into and out of the dome without stooping, crawling, or rushing. The dome remains inflated as audiences enter and exit through the airlock door at their own speed. . Airlock door tubes are also Velcro attached at the bottom and can be spread apart to allow a wheelchair to enter or exit.

The Go-Dome™ has a ventilation system that accommodates many different kinds of usage. The dome's fan inflates both the door and a second vent flowing directly into the dome. This vent has a Velcro sealed flap that can be used to adjust the airflow upward or toward the projector. There are also two small vents in the door. If the door is left open for visitors to come and go during demonstrations, the large vent is left open and the small door vents are closed. If the door is closed for a presentation, then the large vent can also be closed and the small door vents are kept opened. This technique keeps fresh air in the dome without the dome deflating during entry and exit.

The Go-Dome™ also has two unique front floor vents, our "Inflation Self Regulating System" or ISRS, that open when the dome rises and vent through a tube on the outside of the dome. The inflated tube acts as a light baffle if the dome starts to rise off the ground. These self-regulating vents make dome operation easy and prevent the flapping or bouncing experienced by other domes as they over-inflate.

The Go-Dome™ also has a soft light grey matte cloth finish. This smooth, non-glare finish creates a projection surface suitable for full-dome video. The light grey color lowers the cross talk of light bouncing from one side of the dome to wash out the image on the other side. Images appear sharp and the colors saturated.

The cloth surface also absorbs sound and minimizes the echo produced in plastic surfaced domes. It also dampens sounds from outside the dome.

The polyester-cotton cloth never frays and is extremely wrinkle-resistant, even after repeated folding. The cloth Go-Dome breathes, minimizing the stuffy sensation often felt with large groups in plastic domes.

Each seam is both sewn and taped on the outside for maximum durability and to prevent any light leaks. Although Go-Domes are opaque, they can acquire a pinhole light leak over time. These are usually visible only when projecting star fields. A pinhole is easily patched with a small circle of the extra cloth provided and rubber cement.
