Etfe Systems

ETFE (Ethylene Tetrafluoroethylene) is a fluoropolymer-based material. It has been developed by the Dupont firm for the aircraft industry, but it has also been used in modern architecture due to its light permeability and light weight. It is usually applied as 2 layers, 3 layers, in the form of inflatable air cushions, sometimes in the form of a single wall. ETFE material is very thin and lightweight. Approximately 1% of glass weight. When the air blown system is used, the resistance is very high.

ETFE systems are mounted on the carcass frame system with special Aluminum profiles. Blower machines in inflatable cushion systems keep the carriage of the ETFE inflatable cushion systems by entering the system again when extra pressure is required at any illegal part feeding the system.

When designing ETFE systems, it is essential to keep in mind the climatic conditions, aesthetic, acoustic and environmental factors. ETFE inflatable cushions should be used in form, printed and 2 x 3 fold according to the requirement of service. 


ETFE (Ethylene Tera Fluoro Ethylene) is produced as a thin film / foil. The material is made transparent (96%), or colored, between 100 microns and 250/300 microns thick. In projects that require solar control, transparency is added to the ability to print on the surface of the material by performing an additional process on the surface of the material. Special patterns can also be ordered if desired, as are standard print patterns (about 50%, silver-entry scoring).


The systems produced using ETFE Material can be evaluated in two different categories

Single layer applications Mechanical stretching must be applied.

Multi-layer (2-5) application Pneumatic tensioning should be applied.

Single Layer Applications: It should be examined with the approach in Suspended Stretching Systems. The material should be evaluated under prestressing and environmental loads. ETFE material does not behave like other isotropic materials. Owing to its elastic behavior, it is usually supported by rope netting. Application area is higher than pillow systems.
