How long is the service life of the fast and economical air-supported membrane building?

Air-supported membrane structures, with their advantages of rapid construction, economic cost and flexible space, are widely used in various fields such as sports venues, storage spaces and emergency facilities.

1.The air curtain hall is fast and energy-efficient, but is there any guarantee for its service life? This is a matter of operational stability and investment return, and it is a concern for many investors.

2.In fact, the "fast and economical" feature of the air curtain system does not conflict with its long lifespan. The service life of the system is not a fixed figure but is determined by factors such as membrane material quality, design and construction, maintenance and operation environment. The normal service life can reach 15 to 30 years. With high-quality projects and scientific management, the lifespan can exceed 35 years.

3.The membrane material is the core component of the air-supported pavilion and directly determines the lower limit of its service life.

4.The mainstream membrane materials on the market can be classified into three categories: Ordinary PVC membrane materials have low costs and relatively poor UV resistance and weather resistance. They are only suitable for temporary exhibition halls, emergency resettlement houses, etc., and have a lifespan of approximately 5-8 years.

5.PVDF coated membrane material is an excellent choice in terms of cost-effectiveness. By applying a polyvinylidene fluoride coating on the surface of PVC substrate, its corrosion resistance and aging resistance are significantly enhanced, with a lifespan of up to 15-25 years, which is sufficient to meet the long-term operation requirements of most sports venues and storage centers.

6.The high-end PTFE membrane material is based on glass fiber and coated with polytetrafluoroethylene. It can withstand extreme temperature differences ranging from -40℃ to 150℃, has extremely strong resistance to acids and alkalis, and UV rays. Its lifespan can last up to 25-30 years. Some large permanent venues have adopted this membrane material, and its lifespan can be comparable to that of traditional buildings.

7.Furthermore, the climate also plays a role. The lifespan of air-raid shelters in mild climate areas is generally longer, while in coastal areas exposed to salt fog, industrial areas with corrosive gases, and areas under intense ultraviolet radiation, the lifespan is relatively shorter, but it can still reach over 10 years. 

8.With the support of mature materials and technologies, the service life of the air curtain building is sufficient to meet the long-term operational needs in various scenarios. It represents a building solution that combines effectiveness, economy, and environmental friendliness, benefiting both the present and the future.
