*Depending on temperature and humidity.
**The values are indicative. A CM measurement is required.
***In the event of a fire, EPS thermal insulation can prevent the spread of fire, but it does not constitute a fire barrier.
****Minimum thickness to achieve the impact sound values. No minimum thickness for all other applications.
