Etfe Roof Weight

Etfe film is a hundred times lighter than glass and allows more sunlight to pass through.

Etfe roof weight.

Etfe foil is a plastic polymer related to teflon and is created by taking the polymer resin and extruding it into a thin film. The movable roof had to take singapore s tropical climate into account and following extensive testing a new. Etfe foil is a hundred times lighter than glass. Alongside its low weight the major benefit of etfe is its high translucency by transmitting up to 94 97 of visible light 380 780nm and 83 88 of ultraviolet range 300 380nm.

The use of texlon etfe helped reduce the overall weight of the roof and subsequent steel tonnage required and consequently had a huge impact on the overall carbon footprint and energy consumption of the stadium. Developed over 40 years ago by dupont etfe has similar light transmission to glass but at just 1 of the weight. We are the creator of wintess we develop and continuously improve solutions to design analysis and fabrication of tensile structures. Ethylene tetrafluoroethylene etfe is a fluorine based plastic polymer that offers a creative and lightweight alternative to glass.

Class c is the lowest class of non fragile assembly and particularly if engineered to pass the test criteria may be close to the boundary between fragile and non fragile. Etfe foil cushion systems are certified as class c non fragile roof assembly in accordance with acr m 001 200 test for fragility of roofing assemblies. The utilization of etfe cushion decreases steel and aluminum amount required to support structural claddings. This is a vital property for well being of humans and plants.

These include extremely low weight compared to glass exceptional light transmission especially in the uv spectrum a self cleaning effect elasticity long service life and sustainability. The particularly low weight of etfe enables roof designs that would be impossible with other materials. Etfe ethylene tetrafluoroethylene copolymer is a plastic derivative that is frequently used as a building material in the form of etfe membranes. A typical etfe cushion roof weighs 450 g per square meter which means that an etfe cushion roof system weighs 250 100 times less than any transparent roof alternatives and used 50 200 times less embodied energy per square meter.

Etfe is only 1 100 the weight of glass and it has properties that make it more flexible as a construction material and a medium for dynamic illumination. The material is characterized by high light and uv transmittance temperature resistance and very low weight. Etfe foil roofs can be supplied as a single layer membrane supported by a cable net system or as a series of pneumatic cushions made up of between two and five layers of etfe.
