Etfe Roof Fire

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.

Etfe roof fire. A material of limited combustibility en 13501 1 eur class bs1d0. Etfe roofs are superior in terms of safety. The fire rating of etfe to british and european standards which are very detailed in their rating is class bs1d0. Bs476 6 7 class 0.

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. Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point. 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. 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.

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. 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. 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. Texlon etfe foil is a safe building material that is principally employed in the formation of building envelopes.

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. High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane material. 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. Etfe has a melting point of approximately 260 c.

There are some very real concerns about using low melt panels for smoke control. Etfe foils have a very high durability compared to other transparent plastic materials. Why is it not a good idea. The water cube s façade consists of 4 000 texlon etfe bubbles some as large as 9 14 metres across with 15 different sizes.

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. 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.
