The standard requires a minimum laboratory STC rating of 50 for party walls and floor/ceilings. In addition, each assembly references a ROCKWOOL test number, as well as the ROCKWOOL products included in the tested assembly. How Are These Ratings Obtained? Both IIC and STC ratings are essentially decibel ratings. Aug 9, 2023 · The STC rating of a wall partition is the overall ability to resist the passage of airborne sound at 16 frequencies between 125 Hz and 4000 Hz.

The sound transmission loss at each frequency can vary, highlighting the importance of reviewing the assembly sound test. As Thorburn notes, “ In the past, using multiple layers of gypsum sheathing to increase the mass of the system has been the most common solution to raising the STC rating of the system. All assemblies include component descriptions, STC, OITC, and R-values (if available). Products Applications Adding shear wall sheathing to a wall assembly can actually increase its acoustical performance in certain circumstances because it adds mass to the assembly. Similar to STC, the UL U301 — Exterior Walls, Wood Stud (Load-Bearing) UL Wall Assemblies BIM - Revit Library Stc 56; Fire Rating 2 Hour; System Thickness 8-1/2" Mar 5, 2021 · The overall STC rating is an average of the STC ratings measured between 125 Hz and 4,000 Hz. Based on wall, window, and door Sound Transmission Classification (STC) values, the STraCAT generates a composite STC value for the wall assembly as a whole. STC is highly dependant on the construction of the partition. These STC ratings represent common wall and door assemblies. 7 %âãÏÓ 46 0 obj > endobj 74 0 obj >/Filter/FlateDecode/ID[42B4D06FF21B5A41BB85A8E4F3353419>]/Index[46 50]/Info 45 0 R/Length 124/Prev 180377/Root 47 0 R The world's most comprehensive collection of sound-tested, fire-rated assemblies. 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 When the mass of a barrier is doubled, the isolation quality (or STC rating) increases by approximately 5 dB, which is clearly noticeable. PDF. That’s where the STC rating comes into play. Assemco is a leading provider of assembly services, offering a wide range of solutio When it comes to adding extra storage space to your property, a Suncast shed is an excellent solution.
