Insulation sheets and fire safety

Everyone wants to prevent fire. FALK put a lot of energy into the development of its products to improve the fire properties.

We regularly test the fire properties of our products. The results of these fire tests are recorded per product in a certificate. You can use these certificates to demonstrate that a product meets the set requirements. 

Below we listed the most important data regarding fire properties and associated classification. Would you like to know more about the fire safety of FALK Panels? Download the brochure below!

Fire Safety Brochure

Fire class B-s2,d0

The fire class explains the contribution of a product to the development of a fire and/or smoke development. In short, a fire class B-s2,d0 means medium smoke development and nearly no contribution to fire development. The panels of FALK (almost) all have a fire class of B-S2-D0. But what does this mean?

B: This letter gives an indication of product flammability. The level of flammability varies from A to F. How flammable a product is runs from A to F. A is incombustible and F is highly flammable. This means that FALK panels are very difficult to burn as they are fire class B.

s2: The letter 's' means 'smoke'. It explains the smoke development of a product during a fire in three classes: s1 = low smoke production; s2 = average smoke production; s3 = large smoke production. The panels of FALK fall into class s2.

d0: The letter 'd' means 'dripping'. It indicates the amount of droplets and parts that come down and cause new fire sources. Again three classes: d0 = no production of burning parts; d1 = parts burn shorter than 10 seconds; d2 = parts burn for longer than 10 seconds. FALK insulated panels fall into class d0.

Fire resistance
The fire resistance of an insulated metal panel is expressed in minutes. This indicates the time that the wall is able to stop the fire. During a fire test there are three classes of criteria tested:

E: This is the flame density of a panel, or the amount of time it takes for the wall to stop the flames.
I: Thermal insulation of a wall, or the time a wall can withstand the high temperatures of the fire.
W: Heat radiation. This indicates how long it takes before the wall radiates so much heat that another object, at a certain distance will start burning.

The criteria above are not necessarily achieved at the same time. It often happens that fire resistance differs per criteria. Fire resistance is often indicated per criteria (letter) or a combination of criteria. For example EW60 or EI30. Most FALK panels have a specific fire resistance. This varies considerably per product and thickness of the panel. Please contact our team to request the classification of a particular product.
