The Perforated Permanent Planetariums represent the highest level of engineering excellence at EPI Domes. Designed for world-class planetariums and professional immersive theaters, these domes offer unmatched projection fidelity, architectural stability, and decades of uninterrupted performance. Built using precision-formed perforated aluminum screen panels and a reinforced metal support system, the Ultra Dome Pro+ Series sets a new global benchmark for permanent, museum-grade dome installations.
Diameters ranging from 4 m to 30 m.
A selection of standard colors is available, with the option to choose any custom color upon request.
Optional fully customized exterior designs and branding. Negative Pressure Steel Dome
Achieves a perfectly continuous projection environment with no visible panel transitions.
Provides exceptional curvature accuracy, eliminating geometric distortions commonly found in traditional dome constructions.
Multiple coating options tailored for high-brightness or high-contrast projection systems, depending on venue requirements.
Manufactured to museum-grade tolerances, each panel ensures superior optical uniformity and long-term structural reliability.
Perforation specifications are designed for optimized projection performance, acoustics, and internal environmental balance.
Micro-perforation diameter: 1.6–2.0 mm (customizable).
Staggered grid spacing: 3.2–4.0 mm (customizable).
Maximum horizontal panel width: 1000 mm (customizable).
Maximum vertical panel height: 2000 mm (customizable).
Open area ratio: Approximately 18–22.6% for ideal acoustic transparency.
Sound-transmission pattern: Equilateral hexagonal layout.
Applied with precision spray technology for consistent finish and performance.
Provides exceptional contrast, brightness, and projection accuracy.
Ensures seamless and secure panel-to-frame integration.
A 20 mm black acoustic sponge layer reduces echo, enhances sound absorption, and stabilizes internal temperature while minimizing vibration.
