Fire resistance plays an important role in ensuring the safety of buildings lined with sandwich panels. This indicator determines how long a material can resist the effects of fire while maintaining its essential performance characteristics. In the event of a fire, it can be a decisive factor in preserving the structure and preventing the fire from spreading to other areas of the building.

Fire resistance limit of sandwich panels

One of the key parameters that assess the fire resistance of a material is its limit. This parameter is determined by the time during which the panels are able to maintain their strength characteristics under the influence of high temperatures. It depends on the type of material that is used in the construction of the panel, and on the thickness of the insulation layer.

What affects the fire resistance of sandwich panels

An important role is played by the composition of the filler that is used between metal sheets. For example, panels with mineral wool have a higher fire resistance compared to those where polystyrene foam is used. The fire resistance of insulation in sandwich panels can vary significantly, which should be taken into account when choosing a material for construction.

Certification and Fire Hazard Classes

The fire resistance of sandwich panels is confirmed on the basis of certification. The panels are tested to determine their fire hazard class. The higher the class, the more time the panel will be able to resist fire and the less likely it is to quickly spread a fire. For many facilities, especially industrial and commercial buildings, fire certification is a requirement.

Comparison of fire resistance of different types of sandwich panels

Different types of SP have different fire resistance characteristics. In particular, mineral wool shows better results in fire resistance tests compared to expanded polystyrene or polyurethane. Accordingly, the choice of material depends on the specific requirements for the project, including safety.
