VERDEX® has achieved an FIIC of 60+*
*Testing done in accordance with ASTME-1007 "Standard test method for measurement of Tapping Machine Impact Sound Transmission through floor/ceiling assemblies and associated structures".
Please note: The only way to secure an accurate FIIC ratings certification for your project is to conduct an on-site test. Field tests are project specific; comparing different field tests is not an accurate way to make a proper assessment of product performance. The table below demonstrates the wide range of numbers that have been achieved in different concrete slabs that are the same thickness.
