Etfe Roof Weight

Ethylene tetrafluoroethylene etfe is a fluorine based plastic polymer that offers a creative and lightweight alternative to glass.

Etfe roof weight.

Etfe etfe ethylene tetrafluoroethylene is an industrial strength construction plastic used for exterior cladding since the 1980s. 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. 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. This is a vital property for well being of humans and plants.

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. We are the creator of wintess we develop and continuously improve solutions to design analysis and fabrication of tensile structures. 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. The particularly low weight of etfe enables roof designs that would be impossible with other materials.

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. Etfe film is a hundred times lighter than glass and allows more sunlight to pass through. 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. The movable roof had to take singapore s tropical climate into account and following extensive testing a new.

Etfe ethylene tetrafluoroethylene copolymer is a plastic derivative that is frequently used as a building material in the form of etfe membranes. The utilization of etfe cushion decreases steel and aluminum amount required to support structural claddings. 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. Etfe foil is a hundred times lighter than glass.

Developed over 40 years ago by dupont etfe has similar light transmission to glass but at just 1 of the weight. Non linear analysis software for membrane structures creating solutions since hello. 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.
