This system utilizes sleek, aluminum framing and acoustical glass to achieve optimal sound isolation with a range of 35 STC to 45 STC. An STC rating also can be used for doors, windows and floor/ceiling assemblies. 11 of the LABC. This example is obviously a wall To find this section in the catalog, simply assembly, so all sections which begin with look at the right hand column under "Sec- the number “ 2. Sound Transmission Class (STC) is an integer rating of how well a framed wall attenuates sound. To bring the rating to STC 50, another layer is added to the uncontrolled side for four total. Download the Acoustics Overview and sound assemblies to learn more. and Heuer, A. The International Building Code (IBC) requires a 50 STC (45 STC field tested) for wall assemblies between dwelling units and dwelling units adjacent to public spaces. Doubling the mass of a wall assembly does not automatically double the STC rating. In theory. The initial specification for the STC 45 wall design called for 3 layers of Type X gypsum board and the STC 50 wall was originally designed using 4 layers of Type X gypsum panels.
