DERFLEX – Trusted Air Dome Fabric Manufacturer

With the rapid development of air-supported architecture, air dome structures have become an increasingly popular solution for sports facilities, industrial storage, logistics centers, and temporary buildings. At the core of every reliable air dome system lies one critical component: air dome fabric.

DERFLEX is a professional manufacturer specializing in high-performance coated fabrics and membrane materials. As an experienced air dome fabric supplier, we provide engineered solutions designed to meet the strict structural, safety, and durability requirements of air-supported buildings worldwide.

DERFLEX air dome fabrics are widely used in sports air domes, badminton domes, football domes, tennis domes, air-supported warehouses, and large inflatable enclosures.

What Is Air Dome Fabric?

Air dome fabric is a technical membrane material specifically engineered for air-supported structures. Unlike conventional roofing materials, air dome fabric must maintain structural integrity solely through internal air pressure.

This fabric acts simultaneously as:

• The structural envelope of the building
• An airtight pressure-retaining membrane
• A weatherproof and UV-resistant outer shell
• A fire-retardant safety barrier

DERFLEX air dome fabrics are typically manufactured using high-tenacity polyester base fabrics coated with advanced PVC formulations, optionally enhanced with PVDF surface treatment for extended lifespan and easier maintenance.

Main Applications of Air Dome Fabric

Air dome fabric is used across a wide range of industries and applications due to its flexibility, fast construction speed, and cost efficiency.

• Sports air domes (badminton, football, tennis, basketball)
• Swimming pool air-supported structures
• Air-supported warehouses and logistics centers
• Industrial storage domes
• Mining and bulk material enclosures
• Temporary exhibition and event domes
• Emergency and military inflatable shelters

Types of Air Dome Fabric Supplied by DERFLEX

PVC Coated Polyester Air Dome Fabric

PVC coated polyester fabric is the most widely used air dome material due to its excellent balance of strength, airtightness, flexibility, and cost efficiency.

• High-tenacity polyester base cloth
• Double-sided PVC coating
• Excellent airtight performance
• Superior weldability for airtight seams
• Custom weights from 650gsm to 1200gsm+

PVDF Surface Treated Air Dome Fabric

For long-term outdoor air dome projects, PVDF surface treatment significantly improves durability and appearance.

• Enhanced UV resistance
• Self-cleaning surface properties
• Improved color stability
• Reduced maintenance costs

Double-Layer Insulated Air Dome Fabric Systems

Many large air dome structures adopt a double-layer fabric system with an air insulation cavity. This configuration improves thermal insulation and energy efficiency.

• Inner airtight membrane layer
• Outer weather-resistant membrane layer
• Better temperature control
• Lower operational energy consumption

Key Performance Requirements for Air Dome Fabric

Airtightness

Airtightness is the most critical property of air dome fabric. Any air leakage can compromise internal pressure stability. DERFLEX air dome fabrics are engineered with low air permeability and optimized coating formulations to ensure long-term airtight performance.

Tensile Strength & Structural Stability

Air dome fabrics must withstand constant internal pressure as well as external forces such as wind and snow loads. DERFLEX uses high-tenacity yarns and reinforced fabric constructions to achieve excellent tensile strength and tear resistance.

Fire Retardancy

Fire safety is mandatory for public and industrial air dome structures. DERFLEX air dome fabrics can meet multiple international fire standards, including:

• DIN 4102 B1
• EN 13501
• NFPA 701
• BS 7837

Weather & UV Resistance

Outdoor air dome fabrics must resist long-term exposure to sunlight, rain, snow, temperature changes, and aging. DERFLEX air dome materials are formulated for extended outdoor service life.

Advantages of DERFLEX Air Dome Fabric

• Excellent airtight performance
