Etfe Roofing 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.

Etfe roofing material.

Roofing with etfe offers even more benefits. Individuality in design and function. It is stretchable hence a variation in size can be compromised. The texo panel system will hold any architectural fabric at a constant pretension so it will not deflect under wind or snow loads.

Non linear analysis software for membrane structures creating solutions since hello. The water cube of the 2008 olympics the world s largest structure made of etfe film the panels of the eden project are also made from etfe and the tropical islands have a 20 000 m 2 window made from this translucent material. 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 advantage is more effective when etfe are used as a roof material.

Originally invented by dupont as an insulation material for the aeronautics industry etfe was not. 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. 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. High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane 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 is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point. 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. The benefits of an etfe roof compared to a glass equivalent are becoming increasingly recognised.

At aura we can provide you with the unique and patented texo etfe panel solution. We are the creator of wintess we develop and continuously improve solutions to design analysis and fabrication of tensile structures. Selected projects realized using wintess structural revisit to german pavillion expo 67 montreal this interesting academic work by alba lópez gómez diego. This allows you to use etfe in flat or curved panels for your roofing scheme.

Sharp edges create punctures in these materials hence it is commonly used as roofing or as a cladding material. Etfe foils have a very high durability compared to other transparent plastic materials. Etfe foil offers excellent elasticity and its breaking point is higher than that of any comparable material.
