PIR insulation is designed with fire safety in mind. It generally has a higher fire resistance compared to many other insulation materials. While not completely fireproof, PIR insulation is treated to be fire-retardant, meaning it can slow the spread of flames and doesn’t ignite easily.

Like most building materials, however, it’s important to use PIR insulation in accordance with proper safety standards and building regulations. In the event of a fire, PIR can emit smoke and toxic gases, so it’s crucial to combine it with appropriate fire safety measures.
