Fire etfe foil as a material has low flammability 270c and is considered self extinguishing.
Etfe roof fire.
This prestigious project with the head contractor china state construction engineering corporation cscec comprises over 100 000m 2 of texlon etfe foils making this the single largest etfe structure in.
Means etfe is a combustible material with a very limited contribution to fire with a weak quantity speed of smoke emission and no dripping of.
In the event of a fire hot smoke will cause the foil to soften fail and then shrink away from the fire source to create natural ventilation.
Why is it not a good idea.
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 has a melting point of approximately 260 c.
In the event of an earthquake or collision a glazed roof will often shatter which can be extremely dangerous for anyone who happens to be beneath it.
A material of limited combustibility en 13501 1 eur class bs1d0.
Etfe roof at manchester piccadilly station manchester uk 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 realization of etfe foil used for roofs facades and building envelopes for large grandstands domes stadiums or arenas as well as shopping centers or botanical gardens.
It has been argued that because etfe can melt the cushions are able to self vent in the event of fire shrinking back from flames to allow the fire to vent to atmosphere eliminating the need for smoke control.
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.
There are some very real concerns about using low melt panels for smoke control.
Consequently the fire behavior of etfe foil applied in a roof or in a façade area can be described as very safe referring to the flame spread and fire propagation.
In the event of a fire it does not promote the spread of flames because it self extinguishes and does not generate any flaming droplets or particles.
The water cube of the 2008 olympics the world s largest structure made of etfe film laminate.
Etfe foils have a very high durability compared to other transparent plastic materials.
High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane material.
Texlon etfe foil is a safe building material that is principally employed in the formation of building envelopes.
Etfe roofs are also superior in terms of safety compared to glass roofs.
Etfe roofs are superior in terms of safety.
Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point.
