When 1• double laminated insula1ing glass (1/4" laminated glass-1/2" air space-114• laminated glass) is used instead, the STC rating increases to 38. Although very similar, the OITC rating system is aimed at lower frequencies, such as construction work, rumbling engines, low-flying planes, and car horns, and it utilizes a wider frequency new rating to describe products that comply to the standard. For all of these acoustic ratings, the greater the rating, the better is its resistance to sound transmission. 8. Impervia ® Fixed Windows. Jun 28, 2016 · summarized in Table 1 below. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. 14-113-11-R1 Acoustic and Thermal Performance STC: 26 OITC: 21 RValue: 23 Rainfall: 54. It is used to specify the sound transmission loss properties of exterior Pella 2024 Architectural Design Manual Division 08 – Openings Windows and Doors www. 2 Test Method. Two common ratings for windows and doors are the Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) Ratings. Block Frame OITC Rating The Outdoor-Indoor Transmission Class (OITC) is calculated by subtracting the logarithmic summation of the TL values from the logarithmic summation of the A-weighted transportation noise spectrum stated in ASTM E1332. N/A Ultra™ Series Performance Ratings Updated: 7/2020 size bs/vs bs/vs bs/vs Half Vent 6060 -310-3265 LC-PG-30 0. The door assemblies shall be tested in accordance with ASTM E 90. It explains: 1) The STC and RW ratings are based on comparing measured transmission loss data to numbered reference curves, with the number of the best-fitting curve being the rating. One thing that I’m not clear on: how would I know how high of an OITC rating I need? I’m guessing that I would use a sound/decibel meter to measure the undesired noise, estimate a desirable/tolerable noise level (in decibels), and calculate the difference (bad noise decibels minus good noise decibels, if you will). window at two distances Find technical specifications, installation instructions, construction specifications (CSI), CAD/BIM files and parts manuals for all Marvin products.

The charts include While you may be familiar with Sound Transmission Class (STC) ratings, there is another relatively new way of measuring sound transmission: Outdoor-Indoor Transmission Class (OITC).
