What does the compression ratio of mineral wool determine in fire safety applications?

The compression ratio of mineral wool is a critical factor in determining its density and thermal performance. When mineral wool is compressed, it can change in density, which directly impacts its effectiveness as an insulating material. A higher density often leads to better thermal resistance, which is crucial in fire safety applications. This means that mineral wool with an optimal compression ratio will provide superior insulation, helping to slow down the spread of fire and improve the overall fire safety of a structure.

In essence, understanding the compression ratio allows fire safety professionals to select the appropriate type and density of mineral wool for specific applications, ensuring that it meets the necessary performance standards for thermal protection during a fire scenario.
