ETFE
(Ethylene TetraFluoroethylene)

ETFE is fluoropolyten based synthetic material. It has wide usage area.

Cladding, upper enclosure, canopy, etc.

Generally in upper enclosure.

It provides access to use for long spans because of its high tensile strength.

It's recyclable and sustainable but not renewable. It has self cleaning function. It is transparent and it stands very aesthetically.

It can be produced and used with some patterns and colors.

It is utilizable for high tech systems like

Photovoltaic cell and

LED Lighting

Properties of Material

           It has low thermal conductivity.
           U: 1.9 W/m2K
           It has no high resistance against fire.
           Flammability: DIN 4102 Class B1
           It allows high light transmission.
           It is very lighter than the glass with 2-3 kg/m2 average mass.
           Therefore, it is cost effective.
           It has higher tensile stress than glass.
           It provide accessing long spans with light structural systems.
           It has long life time approximately with 25 years.
           It is impermeable against water.

Production Process

           First preparation for CNC cutting, size controlled for layout and cutting, gluing.
           Then inner rope joint for increasing static durability of ETFE.
           Then gluing pocket and cord for mounting to structural aluminium system.
           Preparation for packaging, then shipping/ forwarding.

Finally it is mounted mechanically to aluminium profiles. It has three different usage system: Single layer, double or triple layer. When it is used as double or triple layer, it is inflated consistently with Blower to balance the air.

Finally, we can see that ETFE has large usage areas; cladding, upper enclosure, canopy and we saw that above it can use for sun shading. Also, It can be used for aesthetic purposes.
