Insulation sheets and fire safety

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

We regularly tests to 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. Feel free to ask them.

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

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 an 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. flammable a product is and runs from A to F. A is incombustible and F is highly flammable. This means that FALK panels are very difficult to burn because of fire class B.

s2: The letter 's' means 'smoke'. It explains the smoke development of a product during 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 'drupping'. It indicates the ammount 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 a sandwich panel is expressed in minutes. In the base this indicates the time that the wall is able to stop the fire. A fire can penetrate the wall in various ways. During a fire test, these different criteria are all tested. There are three classes:

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

The criteria above are not necessarily achieved at the same time. It often happens that fire resistance differs per criteria. Fire resistance therefore often indicated per criteria (letter) or a combination of criteria. For example EW60 or EI30. Most panels of FALK have a certain fire resistance. This varies considerably per product and thickness of the panel. We therefore ask you to request the classification per product.
