There are a number of benefits that are to be had from ETFE foil just from this one small fact. If you were to tell someone who wasn’t in the know with regards the properties of ETFE foil, they would likely just say “so is glass” when you mentioned transparency.
What are the benefits that ETFE foil brings through bring transparent.
- · Natural light transmission is far greater than that of glass, therefore creates a more natural feel inside a building. Many schools have begun using ETFE as their roof structure as they have noticed that it makes students more responsive, comfortable, and improves results.
- · Obviously using natural light means that the need within a building for artificial light is massively reduced. This helps buildings to reduce their carbon emissions and see their energy bills shrink significantly.
In keeping with the environmental tomes of the final bullet point above, ETFE also acts as a natural insulator. As well as reducing carbon emissions and energy bills through a reduction of artificial light, the same can be said for heating, too.
Weight and Strength
Perhaps the biggest feature of ETFE is its weight. Weighing only 1% of what glass does, ETFE is much easier to place within a construction. On top of this, it makes it ideal as a building material to be used on older buildings. Many Victorian buildings, for example, are now at the stage where their roof in some cases needs to be completely replaced. Replacing the roof like for like would involve extensive works being carried out to the building to strengthen the overall structure so that it could support such a construction. Using ETFE allows this scenario to be avoided due to its light weight, while a building can also benefit from its many environmental benefits.
As well as being lightweight, ETFE is also exceptionally strong, and under tension is able to support up to 400 times its own weight, meaning that heavy snowfall, for example, will not be an issue.
ETFE is 100% recyclable and is not eroded due to ultraviolet light exposure or air pollution. This means that, where normally a roof would need to be serviced and strengthened every 5-10 years, the period to maintain ETFE is much, much longer. As well as these traits, it also has non-adhesive properties that mean it becomes self-cleaning when it rains.
All of these characteristics together combine to make ETFE the perfect material for use within a roof structure. Already popular, ETFE will become much more common in the years ahead.
Vector Foiltec invented the Texlon (ETFE) which is the perfect material for a roof structure. An ETFE roof has many advantages, including transparency, natural insulation, weight and strength, and low maintenance.
