Inflatable structures are omnipresent across various sectors, ranging from events to industry and leisure.
Their design varies significantly depending on their use, which results in the existence of different types of inflatable structures. In this article, we explore three main categories:
- Closed air structures
- Ventilated structures
- Hybrid structures
1. Closed Air Inflatable Structures
Closed Air Inflatable Structures, often made from high-density PUHD PVC or polyurethane, operate without a continuous air supply. Here are their main features:
• Materials: Use of welded PVC, which is both airtight and highly durable.
• Mode of Operation: Once inflated, these structures maintain their shape without the need for a continuous ventilation system. The air remains trapped within the structure.
• Applications: Suitable for uses that require long durations without maintenance, such as buoys, safety rafts, or permanent decorative elements.
Advantages:
- Very quiet as no fans are required.
- Easy to transport due to its relatively lightweight.
Disadvantages:
Less precise and complex shapes.
Sensitive to punctures, although repairable.
Limitations in terms of size and design to maintain airtightness.
2. Ventilated Inflatable Structures
Made from sewn fabric, these structures require continuous ventilation to maintain their shape. Here’s what sets them apart:
- Materials: A durable fabric, often polyester or nylon, coated with PU-PVC or silicone to resist wear and external elements.
- Mode of Operation: These structures use an active fan to maintain air pressure, compensating for natural air leaks through the seams.
- Applications: Perfect for temporary applications such as inflatable castles, advertising displays, or temporary tents.
Advantages:
- Great design flexibility, adaptable to very complex shapes.
- Less sensitive to local damage as the air is constantly renewed.
Disadvantages:
Noise generated by the ventilation system.
Requires a continuous power source for the fan.
3. Hybrid Inflatable Structures
This hybrid type combines the best of both worlds: a closed air PVC body with an external fabric skin. Here are its specifics:
• Materials: The internal PVC body ensures airtightness, while the external fabric layer provides strength and protection.
• Mode of Operation: The main body is inflated like a closed air structure, while the external skin may require a small air supply or function as simple reinforcement.
• Applications: Suitable for large-scale structures requiring both strength and aesthetics, such as artistic installations or inflatable structures for professional use like inflatable tents.
Advantages:
- Strong and durable thanks to the external layer.
- Allows for bolder and more visible designs.
Disadvantages:
Can be more expensive due to the use of multiple materials.
More complex to produce and maintain.
Conclusion
Each type of inflatable structure offers unique advantages depending on the needs and constraints of the project. Closed air structures are ideal for simplicity and durability, while ventilated structures stand out for their flexibility and adaptability. Hybrid structures, on the other hand, represent a high-end solution, combining performance and aesthetics. By understanding these differences, you will be better equipped to choose the ideal solution for your inflatable projects.
