Etfe Roofing Material

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.

Etfe roofing material.

Originally invented by dupont as an insulation material for the aeronautics industry etfe was not. 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. Non linear analysis software for membrane structures creating solutions since hello. High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane material.

Individuality in design and function. 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 benefits of an etfe roof compared to a glass equivalent are becoming increasingly recognised. Sharp edges create punctures in these materials hence it is commonly used as roofing or as a cladding material.

Selected projects realized using wintess structural revisit to german pavillion expo 67 montreal this interesting academic work by alba lópez gómez diego. Roofing with etfe offers even more benefits. 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. 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. The texo panel system will hold any architectural fabric at a constant pretension so it will not deflect under wind or snow loads. We are the creator of wintess we develop and continuously improve solutions to design analysis and fabrication of tensile structures. 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.

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. Written by amy richardson on 5th march 2009 in etfe. 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 advantage is more effective when etfe are used as a roof material.

This allows you to use etfe in flat or curved panels for your roofing scheme. It is stretchable hence a variation in size can be compromised. 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.
