Comparison of ETFE with Glass
Both systems provide some capabilities like thermal insulation or light translucency. However, ETFE foil cushions offer some benefits over glass.

Structural Characteristics:
ETFE is a very flexible material and is able to cope with large deformations before breakage. Elongations of 200-300% are possible. As being prestressed, it can accomodate the live loads. Glass, on the other hand, is very brittle and works as a plate. As a result, it is subjected to bending moments. ETFE is on the other hand is mainly subjected to tensile stress. The outer layer of an ETFE cushion is the most stressed layer where inner layer is the less stressed one. Middle layer takes almost no load, so basically it is used to created two compartments in the cushion.

The dimensions of a single panel is a major difference between glass and ETFE. ETFE can literally be quite long whereas glass panels are rather limited in size.

ETFE Foil General Properties
ETFE is a modified copolymer which is manufactured and processed by the same methods associated with most thermoplastic polymers.

The general properties of ETFE foil are presented in the table given below:

Advantages of ETFE Foil

Advantages of ETFE Foil:
Very strong and tear resistant
Good translucency and light transmission in visible and UV ranges
B1 class fire resistance. Excellent characteristics for fire emergency situations.
No mechanical or visible aging under stress
Abrasion resistant
100% recyclable
Lightweight
Low coefficient of friction
Printed color patterns possible. This helps in control of heat and light trasmission.
Doesn't react with other substances. Excellent resistance to solvents and chemicals.
Small defects are easy to repair
More than 20 years of life
Hail resistant in cushion applications
High degree UV transmittance
Foil doesn't become brittle over time
Non stick characteristics makes it virtually self-cleaning with little need for maintenance
Wide service temperature range (-200 to +150C)
Very low gas and water permeability
Very low water absorption
Excellent thermal control through multi-layer foils.
Exceptionally high resistance to tearing
Linear elastic behavior up to 20MPa

Who We Are
 was established in 1993. At first, it operated an architectural company in Turkey. Later, it passionately embraced design, structural analysis, fabrication and installation of textile architecture. It achieved many firsts in the field of membrane structures in domestic market.

In an attempt to spread knowledge of membrane, ETFE structures, partners of   established and fully sponsored Institute of Membrane and Shell Technologies, Turkey in connection and as a licensed branch office of IMS e.V., associated institute of Anhalt University, Germany.

Quality assurance throughout the company is of utmost important for  . As a result,   has been accredited to ISO9001:2008 and ISO14001:2004 with a scope of design, engineering, fabrication and installation of tensile membrane structures. Internationally experienced and educated executive team leads to modern and innovation centric project undertaking.

 has long been collaborating with Prof. Ramon Sastre, Catalonya Technical University, Barcelona who is the creator of world renowned software WinTess for membrane structures.

 has proved itself by its achievements, ethical approach to business, long term customer relations through its long history in the sector by delivering quality and reliable service for each project. of any type or size. ‘s success is based primarily on inspiration, ambition, creativity, hard working, continuous education and training.
