The retractable roof screen sits beneath the glass roof, staying hidden most of the time so the space still feels open and filled with natural light. It’s made from a matte black projection fabric that highly absorbs light, supported by a slim aluminium track system built into the structure. When a planetarium event begins, the screen is raised using a simple switch, smoothly extending across the roof to create a dark, continuous surface. This allows the projector to display clear visuals without glare or distractions, making the experience more comfortable and immersive for visitors. Once the show ends, the screen retracts back up, bringing the space back to its original bright, open, and natural state.
