What is EPS made of?
There is no match for EPS
There are those who want to fool you into thinking that some long-established, tried and trusted building solutions are no longer your best option. For example, scaremongering tactics designed to suggest that EPS insulation is anything but a safe bet in a building fire, are far from the flaming truth!
For the record, EPS – like any other insulation material – has virtually no significance in fire safety in a properly designed and well-constructed building.
Here are some important points to help you separate facts from fiction. First when exposed to heat, EPS shrinks away from the source. FR EPS will not be ignited for example by welding sparks or cigarettes and it self-extinguishes when the heat source is removed. Wood will self-ignite when temperatures reach about 340°C. Yet the same happens to EPS at about 450°C.
Secondly, the performance of ‘naked’ EPS is not relevant because, when properly installed behind an inorganic, stone or brick, surface layer, EPS makes it possible to fulfill the requirements for reactionand resistance to fire – giving the same classification results as achieved in identical constructions by mineral wool or PIR.
So don’t let anyone pull the wool over your eyes when it comes to fire safety.
