Air-Supported Halls – Advanced Inflatable Building Solutions by Derflex
Air-supported halls are innovative large-span structures that rely on continuous internal air pressure to maintain their shape and stability. As a professional manufacturer of PVC coated fabrics and architectural membranes, Derflex provides high-performance materials specifically engineered for air-supported hall applications across sports, industry, logistics, aviation, and emergency infrastructure.
Compared with traditional steel or concrete buildings, air-supported halls offer faster installation, lower construction costs, superior energy efficiency, and outstanding flexibility. With decades of experience in coated textile manufacturing, Derflex delivers reliable membrane solutions that meet international standards for strength, fire resistance, weather durability, and long-term performance.
What Is an Air-Supported Hall?
An air-supported hall, also known as an inflatable hall or air dome structure, is a building system where the roof and walls are formed by a high-strength flexible membrane. The structure is stabilized by maintaining a slight positive air pressure inside the building using ventilation and air-handling systems.
The membrane itself becomes the load-bearing element, eliminating the need for internal columns or heavy steel frameworks. This allows for clear-span spaces exceeding tens of thousands of square meters, making air-supported halls ideal for large-scale applications.
- No internal columns – maximum usable space
- Lightweight membrane structure
- Fast installation and dismantling
- Low foundation requirements
- High energy efficiency
Derflex Air-Supported Hall Membrane Materials
At the core of every air-supported hall is the membrane material. Derflex specializes in producing PVC coated polyester fabrics specifically designed for inflatable and air-supported architectural structures.

Main Applications of Air-Supported Halls
Sports Facilities
Air-supported halls are widely used for indoor sports venues such as football fields, tennis courts, swimming pools, and multi-purpose gyms. Their clear-span design and natural light diffusion create an ideal athletic environment.
Industrial and Logistics Storage
For warehousing, aircraft hangars, bulk material storage, and logistics centers, air-supported halls provide rapid deployment and cost-effective coverage for large areas.
Exhibition and Event Spaces
Temporary or semi-permanent exhibition halls benefit from the portability and visual impact of inflatable structures, allowing fast setup and removal with minimal site preparation.
Emergency and Military Use
Air-supported halls are also used for disaster relief, emergency shelters, medical facilities, and military logistics due to their quick installation and scalability.
