    Technical specifications

    General properties:

    • FF-PIR is excellently suited for thermal insulation of ceilings and walls
    • The thermal insulation capacity of the FF-PIR insulation products, whose declared thermal conductivity λD is 0.022 W/mK, enables lesser insulation thicknesses
    • FF-PIR is mold-proof and safe in terms of moisture performance
    • FF-PIR is suitable for use in both new construction and renovations

    Fire performance and chemical resistance:

    • The working temperature of the FF-PIR insulation products is -50…+120 °C, but they can temporarily withstand temperatures of up to +200 ˚C degrees
    • In a fire scenario, the charring of the surface of the insulation will restrain re-ignition
    • The FF-PIR insulation products have a high chemical resistance and they are very resistant to solvents, softeners, and mineral oils

    As the FF-PIR insulation is self-extinguishing, it will restrict the fire from spreading and the charring of its surface restrains re-ignition. However, the FF-PIR insulation products cannot be installed directly on to a chimney, for example, without a 20–120 mm gap in between, depending on the solution and the chimney material.
