Refer to the appropriate product Safety Data Sheet for complete health and safety information. Substitutions of any of the components are not recommended and are not supported by CGC. CGC Shaft Wall Systems have been comprehensively tested for fire resistance ratings only when all of the system components are used together. Next, the transmission loss values are tested individually against eighteen of the most common frequencies. This measures the volume (dB) difference on each side respectively. The first step when attempting to calculate an STC rating is to first measure the 'transmission loss' on either side of the material or structure being measured. Disclaimer: All Ratings Are Not Equal As with any underlayment sound testing number that a company gives you, each subfloor or floor assembly in. The QuietWalk underlayment provides very high ratings such as IIC of 71 and STC 66 as of mid 2018.

To meet International Building Code - both IIC and STC need to meet the minimum of 50 to pass. These ratings exceed the IBC® requirements of 50 STC and 50 IIC and ensure that in buildings constructed with this rating, that loud speech between rooms and footsteps from above will be inaudible. to international standards and have excellent sound rating characteristics: STC of 60 and IIC of 58. The target ratings are dependent on the adjacency and occupancy class on each side of the wall – a band room may not need a high STC wall if placed next to a storage room, but will need one if placed next to a. Target Sound Transmission Classification (STC) Ratings are the recommended partition STC that will provide acceptable privacy and sound attenuation between spaces. The first step when attempting to calculate an STC rating is to first measure the “transmission loss” on either side of the material or structure being measured.

For walls and partitions, the IBC does not stipulate a minimum IIC rating. 1206 of the IBC requires minimum STC and IIC ratings of 50 if laboratory tested or 45 if field tested. Component Additive Method ( IBC 722.6, American Wood Council DCA 4). Additional means to specify fire rated assemblies are as follows: Assemblies listed in our ICC-ES Code Evaluation Report ESR-1153 for TJI joists. The previously UL assemblies held by Trus Joist now have a generic I joist specification and can be found on UL directory searches. Section 1207 of International Building Code 2006 states that separation between dwelling units and between dwelling units and public and service areas must achieve STC 50 ( STC 45 if field tested) for both. The STC rating figure very roughly reflects the decibel reduction in noise that a partition can provide.

Higher values show that more sound is effectively isolated. In short, an STC roughly measures how much a barrier reduces sound. An STC is a rating of how well a wall, floor, door or window assembly diminishes airborne sound and prevents it from passing from one side to the other.

What is STC Rating? An STC is the most common measurement used for sound reduction.
