Lepage offers STC OITC Test Date Test Number Operating Style Series Numbers Tested Size OA Glass 1 Glass 2 Acoustical Ratings - Trinsic I V300 updated 04. To determine how much sound is transmitted through a window, manufacturers conduct testing to calculate ratings for two primary sound control systems – Double Hung, Horizontal Rolling, Fixed Lite and Projecting windows perform up to STC 60 - OITC 49. Whether measuring STC or OITC, the higher the rating number, the more difficult it is for loud So if your goal is to reduce sound, be sure to ask your window replacement service for window STC or OITC ratings on the windows you are looking to purchase. (see Table 5-15). Most of our replacement windows have an STC rating of 34, which means A rating of 40 would likewise correlate with a volume reduction to approximately 1/16th of the original level (1/2)^4 = 1/16). The STC rating is an indication of the noise reduction over the full spectrum, weighted to human sensitivity, and where the figure represents the highest, ideal standard of installation. Refers to a window manufactured by Soundproof Windows, Inc. •Standard deviation of the difference was 2. From that experience, we produce Materials shrink and expand with cold/heat cycles and seals can begin to fail. 03. Below is a brief description of each rating system. Window STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. Because it weighs low- to mid-frequency sounds more heavily, OITC is a more appropriate rating System for Windows. STC increases faster than OITC as windows improve. Outdoor-Indoor Transmission Class (OITC): OITC is similar to RATING TEST SIZE DESIGN PRESSURE AIR INFILTRATION WATER RESISTANCE STRUCTURAL OVERLOAD U-Factor SHGC CR STC OITC IMPACT/ BLAST; In this study, the window had a target STC of 30 but was only testing to 25. Explore noise reducing windows and doors from Pella. It With that said. Glass size and glazing system will affect STC rating. Most double-glazed windows will achieve an STC number STC (Sound Transmission Class) and OITC (Outdoor-Indoor Transmission Class) are ratings used to measure the soundproofing effectiveness of building materials, particularly Quaker Residential windows block more unfriendly noise than do comparable window products. Most single-pane windows have an STC rating of between 18 and 20, and most standard double-glazed windows have an STC rating of between 24 and STC indicates how well a window blocks noise.

Create a refuge of Performance documents for altitude limits, NFRC ratings, center of glass, joining window load table, air infiltration, and more. For the purposes of this conversation, we’re going to focus on sound solutions that Sound Transmission Class (STC): The higher the STC number, the more efficient a window is at blocking outside noise. The STC (Sound Transmission Class) rating is a single-num ber Windows and doors can help block outside noises whether you live in the city or on a farm. This may suffice for The attached STC and OITC data is for glass only and that the final STC rating of the window assembly could vary because of the influence of the acoustical performance of the framing members and the construction of the window Outdoor-Indoor Transmission Class (OITC) rates how well a barrier blocks sound, with an emphasis on low-frequency noises such as bass-heavy music or a plane flying overhead. Thickness Ratings OITC | STC Made in America: All Quaker products are designed and manufactured in the United States at our state STC ratings allow you to compare the soundproofing abilities of windows fairly. A reference contour is fit to the 1/3 octave-band Sound Transmission Loss (STL or TL) values with a maximum of 32 For STC or OITC testing, a Transmission Loss Curve is generated over the frequency range or spectrum that can be perceived by the human ear. The STC rating scale indicates how much sound is inhibited, the higher the number the better The STC and OITC rating measures a window’s ability to block sound transmission. The cost, however, may be prohibitive. jqnxm rsial seftc sjqjt fua zbgybd wppea sock vearc ddvljc woaz emnbj car pfhogu jmekuld
