Etfe Roof Fire

The fire rating of etfe to british and european standards which are very detailed in their rating is class bs1d0.

Etfe roof fire.

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. The water cube of the 2008 olympics the world s largest structure made of etfe film laminate. 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 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. There are some very real concerns about using low melt panels for smoke control. 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. 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.

Why is it not a good idea. Bs476 6 7 class 0. Etfe roofs are also superior in terms of safety compared to glass roofs. High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane material.

A material of limited combustibility en 13501 1 eur class bs1d0. 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. 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. The water cube s façade consists of 4 000 texlon etfe bubbles some as large as 9 14 metres across with 15 different sizes.

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. Texlon etfe foil is a safe building material that is principally employed in the formation of building envelopes. Fire etfe foil as a material has low flammability 270c and is considered self extinguishing. 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.

Etfe has a melting point of approximately 260 c. Etfe foils have a very high durability compared to other transparent plastic materials.
