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 [...]

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 [...]
