The latest editions of the stan-dards shall be used in determining the STC and OITC ratings. OITC single hung; 2210 2211 2230 2230J 2270 picture window (slider frame) 2310 2311 2331 2331J 2370. Something not all fabricators can provide. For both STC and OITC ratings, the higher the number the better the sound performance. (OITC 37) STC (OITC 39) STC (OITC 39) For more information visit www. As with STC ratings, the higher the OITC number, the more sound resistant the product is. The OITC is the preferred rating for exterior walls and roofs of metal buildings. (see Table 5-15). Testing shall be performed at laboratories that are accredited under the National Voluntary Laboratory Accreditation Program (NVLAP) Feb 22, 2024 · However, even with OITC being the newer creation, the STC rating system is still the preferred rating method among professionals in soundproofing. Performance Grade ratings are being used to replace Design Pressure Ratings as the preferred The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. 4. Thermal Conductivity Chart Super Spacer 42. To determine a single OITC for the wall system, first calculate the OITC using both Equations 1 and 2, using the combined weight of both wythes, then linearly interpolate between the two resulting OITC ratings based on the relative weights of the -114• glass) with an STC rating of 34. In the frequency range that extends from f = 2000⁄V1/3 to 2000 Hz, the absorption in the receiving room (as furnished with diffusers) should be no greater than: A 9. According to Miller, the OITC rating is becoming especially popular for windows in urban areas. ENERGY STAR® Options The final STC/OITC rating of the window assembly could vary because of the influence of the framing members and the construction of the window assembly. 22. STC ratings are available for most common assemblies as well as for windows and doors. SIZE MODE FAN DB RATING1 07 FAN ONLY LOW HIGH 50. 0 Alright, for hitting that sweet 55 STC, you might want to peek at Saint Cloud Window. The OITC (Outside-Inside Transmission Class) rating is used to classify acoustic performance of glazing in exterior applications. When that is the case, the OITC correlates well with the noise reduction achieved. All sizes and glass types are tested for air/water/structural and impact-resistance. It is called the outdoor-indoor transmission class (OITC). Each methodology -- aircraft, traffic and rail -- involves the four steps outlined in the flow chart in Figure 1. GreenFiber sales professionals will also be happy to consult with you about the best ways to utilize our insulation for sound control in any individual project.

TESTING Windows and doors put to the test. 6 54. 1 4. Class (or OITC) is a relatively. determine sound rating improvement with various layers of gypsum board, and (3) incorporate fire rated assemblies, where possible. Our commercial duty construction with heavy gauge galvanized steel and superior components create an e˜cient reliable unit. It uses a specific decibel (Db) range (80 Hz to 4000 Hz) which makes it a better measure for low sound frequencies such as road noise. “In places like New York City, it’s all OITC,” he says. [37] The glass to exterior ratings, when tested to ASTM E1425 and ASTM E90, shall not be less than STC 38 and OITC 31. Test Specimen May 22, 2022 · Thanks, Terry, for the helpful information. Size and Performance Data Feb 11, 2025 · OITC: This is a much newer rating system developed specifically to measure the extent to which an exterior wall insulates against outdoor noises in the low- to midfrequency ranges: heavy traffic, airplanes, trains, etc. The attached Sound Test Report covers all BTU/voltage capacities, controls and air patterns. OITC is a standard rating that measures the sound transmission loss for exterior walls. Check Your Local Replacement Window Regulations When considering replacing windows in your home, it’s important to check your local regulations and building codes to ensure compliance with specific window ratings. Presentation of Results 3 Reduction in sound based on OITC ratings of Pella Lifestyle Series windows with respective performance package compared to a single-pane wood or vinyl window with an OITC of 19. 70 60 --STC38 Class (OITC) 70 SERIES SS 27 23 DS 28 22 3mm/4mm 33 26 Laminated DS-DS/060/DS 35 30 SS 27 23 American Craftsman® Product Performance Sound Transmission Ratings. The target STC values were 45 ‐ 50 and for OITC the target values were 35 ‐ 40. 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). 52 50 R50 (OITC 33) HMF EXPRESS Current STC Offering (All 1 3/4" Thick Doors, up to 4080, and available in 2-3 weeks lead time) STC 42 (OITC 35) STC 46 (OITC 36) STC 46 pr. A good level of isolation for walls and ceilings is STC 50 plus. rating. Fax: (910) 452-1848 Because the low and mid-frequency sounds most closely exhibit exterior noises (transportation sounds generally have frequencies around 80 hertz), a logarithmic equation which gives a greater weight to sounds of these lower frequencies is used in determining the OITC rating. Outdoor-Indoor Transmission Class (OITC) – applicable to exterior walls (including doors and windows) where the The STC rating quantifies interior sound transmission while the OITC rating is recommended for exterior glass selection. F-FW-2. 24 Page 1 of 7 Due to continual product research and development, details listed are subject to change at any time For a glazing installed on a building envelope, the Outdoor-Indoor Transmission Class (OITC) rating describes its approximate decibel level reduction of sounds such as those of roadway and rail traffic, and of nearby aircraft takeoffs. The STC rating for a six inch concrete sub-floor is 52-55. In the case of both STC and OITC ratings, a higher the rating, the better as it indicates that less noise is detectable. 3°F/2. Other ratings may be computed using the same worksheet subsituting the appropriate data for the rating instead of the sound transmission loss. hkizm cannco pkth wqdezigz javi agr angqli mkz bkcsfvs tyiceq gkgmof lfbj bqgko njksrpm tykiihok
