What does ETFE stand for?
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.
Is ETFE environmentally friendly?
More Efficient than Glass These measures include energy savings, emissions reduction, water efficiency and indoor environmental quality. ETFE film is safer and lighter in weight than glass, so it requires less structural support. This means buildings using ETFE use fewer heavy materials like steel.
How do I install ETFE?
ETFE Film Installation
- Placement of aluminum profile on the construction.
- Final form of the etfe system before being inflated with air pressure.
- Assembly of the machinery and installation.
- Making the final checks before inflation.
- Starting inflation.
- Completing the inflation.
- Balancing the air pressure.
What is an ETFE roof?
Ethylene Tetrafluoroethylene, ETFE, is a kind of new generation plastic having high chemical resistance and mechanical strength over a very wide temperature range. It is a very molecularly stable material.
Where is ETFE used?
ETFE is commonly used in the nuclear industry for tie or cable wraps and in the aviation and aerospace industries for wire coatings. This is because ETFE has better mechanical toughness than PTFE.
What is ETFE architecture?
ETFE (Ethylene Tetra Fluoro Ethylene) ETFE is a film made of copolymer extruded into thin films, that has been around since over 30 years. Firstly used in the naval industry it began to make its way into the textile architecture due to its high transparency and lightweight.
Is ETFE cost effective?
Cost-Effectiveness – ETFE is an economical alternative. Not only is it substantially less expensive than glass; the lightweight membrane means less dead load on the supporting structure, which translates into major cost-reductions in the necessary structural framework.
Is ETFE sound proof?
Lightweight fabric membranes such as ETFE pillows have interesting acoustic properties due to the inherent thickness, weight, and airspace: At low frequencies (31.5–250 Hz), the stretched material is almost 100% acoustically transparent, and sound at low frequency will pass directly through.
How is ETFE connected?
ETFE cushion systems get their structural stability and ability to withstand weather conditions through pneumatic pressure (around 250-300pa). As a result, every ETFE cushion system is continually connected to an air handling unit from which air pipes run to each individual cushion.
What is the difference between ETFE and PTFE?
PTFE is constructed from carbon and fluorine atoms whereas ETFE is built from carbon, fluorine and hydrogen. Giving advantages to using both. The tensile strength of ETFE can be as much as 38% greater than PTFE, meaning ETFE material can be subjected to harsher operating conditions than its counterpart.
Is ETFE more expensive than glass?
EFTE cushions can be installed for approximately HALF the price that of a high-performance glass roof can. However, ETFE isn’t to be considered a cheap alternative, it’s a highly engineered, specialist quality product, and continues to be more cost effective than glass even after it has been built.
Is ETFE flammable?
ETFE Foil as a material has low flammability (270C) and is considered self-extinguishing.
