ETFE cushions consist of two or more layers of film that are welded together at the edge. The cushions may vary in shapes and sizes, depending on weather loads (snow, wind, rain) and building geometry. The edge is clamped with a keder, which is a cord welded into a narrow pocket. A multi-part aluminum frame profile makes the connection to the supporting structure. Here, an extruded aluminum profile receives the keder in a groove and is then hooked into a base profile that is connected to the supporting structure. Depending on the profile system, cover profiles or retaining screws ensure a permanent, force-fit connection between the cushion and the supporting structure.
Benefits of ETFE Air Cushion Membrane
Exceptional Durability: With an impressive lifespan exceeding 25 years, ETFE has an anti-aging ability. This durability makes it a long-term investment for any architectural project.
Self-Cleaning Performance: The smooth surface of ETFE film makes it a self-cleaning material. Dust and dirt can be easily removed from the membrane structure of the ETFE film. Reducing maintenance requirements and costs overtime.
Climate Resistance: ETFE’s working temperature range spans from 200 to 150℃, with a melting point of approximately 275℃. This gives ETFE exceptional stability and adaptability to various climatic conditions. It maintains its mechanical and optical properties after more than 15 years of exposure to severe weather. ETFE’s weather resistance makes it a reliable choice for outdoor structures.
Natural Lighting: ETFE boasts high translucency, transmitting up to 95% of light, making it perfect for projects requiring high light and UV transmission, such as large-span roofing, skylights, and facades. Additionally, ETFE film absorbs most infrared light, which can be harnessed to improve a building’s energy efficiency.
Environmentally Friendly: The eco-friendly and recyclable characteristics of ETFE supports sustainability in construction, making it an ideal choice for architectural projects throughout the world.
Fire Safety: ETFE’s high melting point is approximately 260°C. It doesn’t generate flaming droplets or particles in case of fire. Coupled with its ability to self-extinguish – and not promote the spread of flames – makes it a safe choice for construction. With all of its flame-resistant properties, ETFE meets various international and national fire safety standards.
Core Properties of ETFE Membrane
ETFE membranes boast a light transmittance of up to 95%, earning them the nickname "flexible glass." They effectively channel natural light, reducing reliance on artificial lighting.
Light transmittance can be adjusted (down to 50%) through surface printing or varying membrane layers to suit diverse lighting requirements.
Ultra-lightweight (0.15–0.35 kg/m²) with a tensile strength of 50 MPa and elongation at break exceeding 300%.
Resists extreme weather (e.g., strong winds, hail) and maintains structural integrity.
25–35-year lifespan without degradation from UV exposure or chemicals.
Anti-adhesive surface allows rainwater to wash away dirt, requiring cleaning only every 5 years with minimal maintenance.
Fully recyclable, aligning with green building standards.
Thermal insulation can be optimized by adjusting membrane layers (e.g., double- or triple-layer cushions), achieving a thermal transmittance (K-value) as low as 2.0 W/(m²·K).
Internal pressure adapts to external loads, enabling self-stabilizing structures.
