Designing assemblies requires a balance between acoustic separation and fire protection. USG products and systems were the first to ensure that all sound systems are fire-rated and easily specified by a UL Design number. USG 1- and 2-hour rated floor assemblies feature USG Levelrock® Brand and USG Durock™ Brand underlayments and USG Levelrock® sound attenuation products and are designed to meet the current International Building Code (IBC).
Find 1- and 2-hour rated assemblies in the 2016 USG Levelrock & USG Durock Fire & Sound Rating Guide (IG1685). For more information, contact your USG/Alcorp Technical Representative at 817 329.1808 or find a representative here.
