Stc Tables, Learn what level of sound isolation each rating provides and which STC value your project requires.

Stc Tables, The STC and ISO RW values indicate the acoustical performance ratings, with higher numbers indicating better sound UBC requirements for walls: STC rating of 50 (if tested in a laboratory) or 45 (if tested in the field*). Acoustic Performance Data Tables Viracon Acoustical Glass is made from combinations of various glass types along with acoustical window frames to help you effectively reduce sound transmission from airplanes, trains, vehicles and other unwanted noises. With the widest offerings on the market and a customer service staff ready to offer full support , we are confident you’ll find the appropriate sound-control solution you need for your project. Many tables are in downloadable XLS, CVS and PDF file formats. This added benefit of cellulose is especially important for apartments, condominiums, offices, motels, and hotels, as well as your home. Products and corresponding data in this document are intended to provide comparative estimates between glass configurations. UBC requirements for floor/ceiling assemblies: STC ratings of 50 (if tested in a laboratory) or 45 (if tested in the field*). Outside the US, the ISO Sound Reduction Index (SRI) is used. All too often this plenums and suspended ceilings unbaffled ducts window to window (outdoors) common heating units transoms and air grilles unblocked joist spaces uncaulked wall perimeters ducts, piping and fixtures masonry joints Can increase the STC rating of a double-layer, steel-framed partition from 29 to 53 STC An integral part of high-performance USG partition designs for attenuation of low-frequency sound from machinery and music Suitable for use at the perimeter of fire-rated wall assemblies For more information see the following brochure: Calculated values of STC are listed in Table 1. It lists the construction details and thickness of single laminated glass, laminated insulating glass, airspaced glass, monolithic glass, and various wall constructions. s9g, yeo, jaloib, ekxrf, cdbkq, mfje6, sr6b, 8wmae, nl, n4,
