Etfe Roofing Material

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.

Etfe roofing material.

We are the creator of wintess we develop and continuously improve solutions to design analysis and fabrication of tensile structures. It is stretchable hence a variation in size can be compromised. Etfe foils have a very high durability compared to other transparent plastic materials. At aura we can provide you with the unique and patented texo etfe panel solution.

Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point. The swiss architecture team of jacques herzog and pierre de meuron created a sculpted look for the allianz arena 2005 one of the most beautiful etfe structures in münchen. The texo panel system will hold any architectural fabric at a constant pretension so it will not deflect under wind or snow loads. The benefits of an etfe roof compared to a glass equivalent are becoming increasingly recognised.

Generously sized rooms without supports minimal use of materials and environmentally responsible construction methods are all possible through the use of etfe membranes in addition due to continuous improvement of the material itself buildings and structures utilizing our films are setting new aesthetic and technical standards. Roofing with etfe offers even more benefits. If you chose nowoflon et as your etfe foil the tensile strength is rated at 23 n mm at the limit of the material s plasticity at the elastic limit and 55 n mm at break. This allows you to use etfe in flat or curved panels for your roofing scheme.

This advantage is more effective when etfe are used as a roof material. Selected projects realized using wintess structural revisit to german pavillion expo 67 montreal this interesting academic work by alba lópez gómez diego. Etfe foil offers excellent elasticity and its breaking point is higher than that of any comparable material. Non linear analysis software for membrane structures creating solutions since hello.

Ethylene tetra fluoro ethylene not the sexiest of names however etfe foil is fast becoming one of the most exciting materials in todays design industry and has set the construction world alight with the potential it offers. An example of its use is as pneumatic panels to cover the outside of the football stadium allianz arena or the beijing national aquatics centre a k a. Individuality in design and function. Sharp edges create punctures in these materials hence it is commonly used as roofing or as a cladding material.

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. A photo journey of etfe architecture quickly dispels the notion that this is a simple plastic cladding material you might put over your roof or boat on a rainy day. Originally invented by dupont as an insulation material for the aeronautics industry etfe was not.
