The ability of a building element to hold back fire
This term indicates how well a building element can hold back fire and prevent it from moving from one room to another for a stated period of time.
Fire resistance of a building element is characterised by 3 criteria:
- R: Load bearing capacity
- E: Integrity
- I: Insulation
For example, a building element that can fulfill these criteria for 30 minutes will be classified REI30.
The fire-resistant properties of stone wool ensure ROCKFON ceiling tiles provide excellent fire protection.
All countries in Europe have adopted minimum requirements for fire resistance. Although fire resistance testing and classification in Europe are standardized, the test method and required classification vary from one country to another.
