Warmer Climate North; Lowest U-factor you can afford Low U-factor: South: Highest SHGC, Lowest U-factor : you can afford Low SHGC (and lots of shade), Low U-factor: East: Low SHGC (or shaded) Acoustical Guide – Determining Minimum STC Rating Methods for Determining Required Window STC Rating The three methodologies discussed below for determining the minimum required STC of windows are identical in format. Interior Glass . Glazing System. The glass to interior ratings, when tested to ASTM E1425 and ASTM E90, shall not be less than STC 38 and OITC 30. To determine the specific STC ratings of glass and a of about 20 to a high of 55. OVER FOUR MILLION UNITS INSTALLED -114• glass) with an STC rating of 34. One of the windows available here is the Sound and Security window by PGT. Is Complete Soundproofing Possible? Our STC rating chart above only goes to 50 because STC rated windows are in that range. This range is broader than the STC range and includes lower frequencies often associated with The U. Crystal Lake, IL. Our expertly crafted solutions provide unbeatable protection against noise pollution, while preserving natural light and design flexibility. STC OITC Test Date Number Operating Style Series Numbers Tested Size OA Glass 1 Glass 2 Acoustical Ratings - Tuscany I V400 updated 09. These ratings are all single numbers used for comparison of various assemblies. View Oitc (www. STC and OITC requirements are increasingly common for projects; using laminated glass is a great way to meet those acoustical requirements. Watch this video on YouTube. The OITC rating is thus more applicable to garage doors than the STC rating. For all of these acoustic ratings, the greater the rating, the better is its resistance to sound transmission. The OITC rating system is mostly consulted when there are The OITC rating represents transmission loss results from 80 to 4,000 Hz using a different mathematical equation than the STC rating. STC Rating. Double-Hung; 37" x 59" 11/16" 2. 2 This classification requires data in one-third octave bands from 80 to 4000 OITC ratings measure how well a barrier blocks sound between an outdoor and indoor space, especially low frequency noises like planes and cars. All files. Updated: 07. oitc. TESTING Windows and doors put to the test. Sound Control Sell Sheet [PDF] SELECT ALL DOWNLOAD SELECTED. Custom Windows and Doors | 7 achieve ENERGY STAR® ratings with customized glass options like gas fills, tints, and coatings. (4) Not available with triple-pane glazing. 3 cfm/ft2), the product The IEC has developed the ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids. The STC and OITC rating measures a window’s ability to block sound transmission. Because of the larger range in expected sound, OITC values are determined for lower frequencies as well, in the range of 80 to 4000 hertz. Other ratings may be computed using the same worksheet subsituting the appropriate data for the rating instead of the sound transmission loss. OX,XO. 3 Phone: 888-815-9691. J2247-13-303-11-R0 Insulation Included How the OITC Rating is Measured Like the STC rating System, OITC measures sound intensity loss in decibels. For a typical single • National Fenestration Rating Council® (NFRC) • Texas Department of Insurance • STC (Sound Transmission Class) • OITC (Outdoor-Indoor Transmission Class) See the Glossary of Terms for more details on each of these certifications and testing protocols. STC Rating Chart. • Doubling the mass of a wall assembly does not double the STC rating. 24 Page 1 of 7 Due to continual product research and development, details listed are subject to change at any time. Acoustic Ratings - Interior Doors: they let pass through. Single Hung Windows. Actual performance in real-life applications will depend on the exact configuration and the framing system used. Following the guidance of ASTM E1332 (Standard Classification for Determination of Outdoor/Indoor Transmission Class), the OITC rating is calculated within the frequency includes both STC and OITC ratings for steel and wood stud walls, considering both interior and exterior assemblies. Use two coatings on two piles of Hermetically sealed IG units paired with laminated glass perform well in ASTM sound transmission ratings. However, architectural acoustics can often become a bewildering array of alphabet soups (STC, OITC, and IIC, to name a few!), and even acoustically experienced architects and designers can be left scratching their heads. greenfiber. Consequently, the outdoor-indoor transmission class (OITC) can also be affected by these factors, resulting in some uncertainty of the field Outdoor/Indoor Transmission Class (OITC) is a newer rating system developed specifically for measuring sound transmission of low- and mid-frequency noises through exterior walls. 24 Page 1 of 7 Due to continual product research and development, details listed are subject to change at any time STC 24 / OITC 18 No Insulation STC 29 / OITC 20 R-10 Faced 202-96 Insulation Over the Purlins STC 32 / OITC 22 R-19 Faced Insulation Over the Purlins STC and OITC Ratings for Typical Metal Building Constructions Walls Roofs STC 54 / OITC 39 R-13 Faced 202-96 Insulation Over the Girts 3 5/8” Steel Studs on 24” Centers with R-11 Batts and 1/2 8. Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC): When tested to AAMA Specification 1801 and in accordance with ASTM E1425 and ASTM E90, the STC and OITC Rating shall not be less than: IR 501UT: a. Mercyhealth Hospital & Physician Clinic. For a single lite system, an increase in glass thickness will reduce the sound transmission and Class (OITC). It includes the Sound Transmission Class (STC) rating and Outside-Inside Transmission Class (OITC) rating, as well as sound transmission loss data across a range of frequencies, for various glass makeups and The OITC rating (referenced in ASTM E1332, Standard Classification for Determination of Outdoor/Indoor Transmission Class) is calculated from the following formula, using a logarithmic summation of individual third OB TL measurements: OITC = 100. 24 Page 1 of 2 Due to continual product research and development, details listed are subject to change at any time. Here’s a chart -114• glass) with an STC rating of 34. STC Ratings; STC Value Rating The Outdoor-Indoor Transmission Class (OITC) rating, calculated according to ASTM E1332, measures the capacity of a window or door to reduce the transmission of exterior noise to the interior of a building across the frequency range of 80 to 4000 HZ. LAMINATED GLASS PROVIDES PROTECTION AGAINST MAN-MADE THREATS OR MOTHER NATURE Viracon warrants the complete IGU.
