With a letter "F" like Fire in the product name, Ruukki introduces a new family of sandwich panels with PIR core, which will be the strongest group in Ruukki’s portfolio when it comes to fire safety parameters. This group includes only panels with visible fasteners (SP2B and SP2E) in both STANDARD and ENERGY versions.

The main features of F-PIR panels are:

• Reaction to fire B-s1,d0 (according to EN 13501-1)
• Very high fire resistance values up to EI 60 (according to EN 13501-2)

Excellent fire safety properties of F-PIR and F-PIRS panels from Ruukki were additionally confirmed by independent laboratory tests made by the insurance company FM Global in the US. In the tests performed in accordance with FM 4881 and 4480 norms, Ruukki’s panels received a positive evaluation as to their use as external walls and internal partitions of buildings without any height limitations (it refers to panels within the thickness range from 100 mm to 200 mm).

A newcomer in F-PIR is a panel with 80 mm thickness, which in line with FM requirements can be used for internal walls (partition walls/ceilings) based on FM 4880 tests.

With top-class results regarding reaction to fire and fire resistance, Ruukki’s sandwich panels with F-PIR core ensure the highest level of fire safety for industrial, office or commercial buildings. Considering the fact that protection of people and property against the fire is one of the key safety priorities for investors, F-PIR panels from Ruukki are the most recommended choice for each construction project.
