Air Dome Building vs Aluminum Tent

1. Structural Load-Bearing Principle

Air Dome:
The structure is supported by the internal and external air pressure difference, which stabilizes the entire envelope system and accessories.

Aluminum Tent:
Uses aluminum alloy frames (main truss, purlins, and roof panels) to jointly bear external loads such as wind, rain, and snow.

2. Roof System Weight

Air Dome:
Double-layer membrane (outer + inner) with optional insulation layer. Lightweight: approx. 2.5–5 kg/m².

Aluminum Tent:
Aluminum beams, purlins, roof panels, and optional insulation. Heavier structure: approx. 20–40 kg/m².

3. Foundation Requirements

Air Dome:
Uses strip foundations. Loads are mainly upward tension forces, resulting in a simple and efficient stress system.

Aluminum Tent:
Requires independent column footings and foundation beams, bearing tension, compression, and shear forces. The stress system is more complex and demanding.

4. Lighting & Natural Daylight

Air Dome:
Uses translucent diffusion membrane for natural lighting. Indoor lighting is achieved through reflected light, no glare, soft and comfortable atmosphere.

Aluminum Tent:
Relies on skylights or roof panels for daylight. Lighting is mostly direct light, which may cause glare and uneven illumination.

5. Fire Safety

Air Dome:
Made of inherently flame-retardant materials. No additional fire treatment required. In case of fire, loss is relatively limited.

Aluminum Tent:
Requires additional fire protection treatment. In case of fire, potential losses are higher due to rigid structure and materials.

6. Waterproof Performance

Air Dome:
Uses high-frequency welded joints, forming a fully integrated waterproof system with excellent sealing performance.

Aluminum Tent:
Connected with self-tapping screws and panel joints, which may cause potential leakage risks and maintenance difficulty over time.

7. Construction System Integration

Air Dome:
Highly integrated system with minimal on-site cross-work. Fast, clean, and well-organized installation process.

Aluminum Tent:
Requires coordination of multiple trades on site, resulting in more complex and fragmented installation management.

8. Seasonal Usage Flexibility

Air Dome:
Can be designed as a seasonal or temporary structure, easy to adapt for different uses.

Aluminum Tent:
Generally used as a permanent or semi-permanent structure, less flexible for seasonal relocation.

9. Installation & Relocation

Air Dome:
Installation and dismantling can be completed within one day, extremely fast and highly relocatable with very low cost.

Aluminum Tent:
Installation takes longer and dismantling requires more labor. Relocation involves higher cost and partial material loss or reinstallation of anchors.

10. Installation Requirements

Air Dome:
No highly skilled labor required. Simple training is enough. Installation method is independent of membrane type, making site management easy and efficient.

Aluminum Tent:
Requires skilled technicians. Training cycle is longer, and different structures require different installation knowledge, making site management more complex.

11. Construction Time

Air Dome:
Typically completed in a few days (less than one week) with minimal weather impact.

Aluminum Tent:
Usually takes several weeks to over one month, and is more affected by weather conditions.

12. Appearance & Premium Aesthetic

Air Dome:
Modern, futuristic, and smooth membrane form. The seamless curved structure delivers a high-tech, luxury, and iconic visual impact, especially attractive for sports venues, exhibitions, and commercial branding.

Aluminum Tent:
Traditional frame-based appearance with visible structural joints. Functional but less visually iconic and less architectural impact compared to air dome structures.
