Sharp edges create punctures in these materials hence it is commonly used as roofing or as a cladding material. 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.

Etfe foil offers excellent elasticity and its breaking point is higher than that of any comparable 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. 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.
