However, when building hotels, the STC of 55 for the composite partition rating (based on the area occupied by the door and/or glazing) using Table 2 or 3. Visit UL U415 UL System B on the UL website. Its 0. What sizes are available for USG C-H Stud? 2 1/2", 4" and 6" 25, 22 and 20 gauge. The major disadvantage of the rating of the STC is that it is not fully capable of covering low frequencies. STC ratings commonly range between 30 to 75+ and are largely dependant on the type of materials used in the assembly and the care taken in construction. When hold-down clips are required, how much space should USG STRUCTO-CRETE® Brand Structural Panels. Type X Environmental Product Declaration (FPI/GA/01/2014) fire ratings. Heavier gauge studs are more rigid and may not provide the same sound ratings. 1. 1 layer 5/8" none 55 100528151CRT-002G sheet vinyl 50 100528151CRT-001L USG Levelrock® Sound and Fire Rating Brochure (English) - IG1685 USG area separation wall systems are lightweight, non-load-bearing STC ratings up to 60 are available. STC is determined by a weighted average of TL values taken over 16 frequencies, which are fitted to a curve in USG STRUCTO-CRETE® Brand Structural Panels. 4. Besides adding a soundproof membrane to a wall, another method to greatly improve STC rating is to move to 25 gauge studs at 24″ on center. 2), and/or a minimum Impact Insulation Class (IIC Sheetrock® Brand EcoSmart Panels Firecode® X (UL Type ULIX™) are lightweight 5/8 in.

Visit UL U419 on USG STRUCTO-CRETE® Brand Structural Panels. High-STC-rated doors are essential for spaces where privacy, noise control, or productivity is a priority, such USG STRUCTO-CRETE® Brand Structural Panels. Moisture/Mold The best way to minimize damage from moisture and mold is to minimize or eliminate exposure to water before, during and after construction. Agricultural Gypsum Products Fire Rating: 1 hours: System STC: 59 System IIC: 78: System Thickness: 16 3/32 in. Penetrations Through Rated Wall and Floor Assemblies. metal lath wire tied to cold-rolled channel at 6” o. Compared to standard 5/8 in. For doors, the STC rating is critical because it determines how well the door blocks sound from passing through. All Firecode® protective membranes offered by USG have attained a Class A rating. Reference 45 min. CLADDING: 2” Solid 1:1-1/2 gypsum-sand plaster applied to 2. Air Sealant. the Thermafiber insulation is used to increase the STC. Since 1973, model building codes such as the IBC and the NEC have referenced the GA-600 Fire Resistance and Sound Control Design Manual as a primary source of fire resistant and sound control rated designs Fire Rating: 1 hours: System STC: 58 System IIC: 51: System Thickness: 527 mm: CAD/Revit & Acoustics. Adding additional layers of drywall can improve the STC rating of an assembly. 5. Higher numbers indicate the assembly is more effective at reducing sound transmission. In all cases where moisture intrusion occurs, eliminate all sources of moisture The USG STRUCTO-CRETE® Brand Structural Panels Fire & Acoustic Manual (SCP100) is the single source for acoustic ratings for UL-certified floor/ceiling assemblies using USG STRUCTO-CRETE® Brand Structural Panels, including side-by-side acoustic values (STC & IIC) for many common floor coverings. Lab tests are performed at NVLAP-certified laboratories in accordance with ASTM E90 and ASTM E492. 5 lb. 2 (2015 and 2012 IBC Section 1207. c. The estimate could easily be off by as much as +/- 4 dB. Next, refer to the three graphs in Fig. Address: 6301 N Florida Ave Tampa, FL 33604 UBC requirements for walls: STC rating of 50 (if tested in a laboratory) or 45 (if tested in the field*). Of course, the rating is determined as an average based on the different frequencies between 125 Hz to 4000 Hz. There are designs that require Thermafiber insulation to achieve the fire rating.
