Paroc stone wool products are made of natural stone, and only small amount of binder is added in the production process. They are non-combustible and can be used in all types of buildings without restrictions. The non-faced products are classified into the Euroclass A1 and the products faced with aluminum foil or glass fiber tissue into the Euroclass A2 (EN ISO 13501-1).
The high melting point makes Paroc an ideal material for the use in the fire insulation applications. Partitions are designed to restrict the fire penetration from one fire zone to another. The fire resistance of the partitioning can be considerably increased by filling the cavity with Paroc slabs. Fire insulation is also necessary to protect the frame structure which carries the loads and prevents the building from collapsing in a fire. Paroc fire insulation slabs are approved for fire protection of load bearing steel and concrete structures.
In acoustic linings and applications where the insulation product is left open it is necessary to fulfill the requirements for ignitability, spread of flame and smoke generation. Paroc products meet the most stringent requirements of the surface criteria which allow them to be used in all parts of the building including the hallways and the technical facilities.
