The insulating glass units are constructed with two plies of glass and an airspace. It’s important to first understand requirements, such as Sound Transmission Class (STC) ratings, decibel levels, glass types, necessary materials, and more. This means you can easily hear loud speech through the window. Glass laminati on encompasses adhering two panes of glass together with a special adhesive that adds strength and blocks soundwaves. This rating will give you an idea of how effective your chosen materials or construction methods are at reducing sound transmission. This STC Wall Calculator estimates the Sound Transmission Class (STC) rating of a wall assembly based on various materials and configurations. An STC rating is an instrument measurement of how much noise is stopped. It is important to note that STC Ratings are measured on a logarithmic scale: the values are not linear. Owens Corning™ EcoTouch® PINK® FIBERGLAS® Insulation is Sound Transmission Class (STC) rating, calculated according to ASTM E413, measures the sound insulation of a window or door across the frequency range of 125 to 4000 HZ, primarily covering human speech frequencies. STC ratings are determined by laboratory tests of a specimen of the construction system, which is fixed within a frame to form the wall between two test chambers. To achieve these ratings and above, a dual window configuration with two sets of sash or a prime window with an exterior or interior storm panel is generally required. For example, a standard single-pane window generally has an STC rating of 25, but the industry average for residential STC-rated windows usually falls around 38. Walls. For example, in residential buildings, high STC ratings are often sought for walls separating different units to ensure privacy. STC Ratings for Everyday Materials. The ASTM frequency range is from 125 to 4000 Hz, while the ISO frequency range is 100 to 3150 The concepts of Noise Reduction Coefficient (NRC), Sound Transmission Class (STC), and other acoustic ratings are vital in designing spaces that meet your acoustic and aesthetic requirements.

Starting from a single 6mm glass lite with an STC of 31, we can achieve STC ratings of as high as 50 with different combinations of laminated and insulated glasses. Wall Assembly. This is different from the rating of that same glass once included into a window A: Based on our experience at the Architectural Testing Acoustical Laboratory, an OITC rating of 32 or STC rating of 40 is very difficult to achieve on a window with conventional 1" insulating glass. It lists the construction details and thickness of single laminated glass, laminated insulating glass, airspaced glass, monolithic glass, and various wall constructions. Calculating STC Ratings for Masonry Walls. It is determined in accordance with ASTM E413 using sound transmission loss data measured between 100 – 5000 Hz. Therefore, sound measuring at 50 decibels is not twice as loud as a 25 The STC rating will usually be quite similar to the classification outlined in ISO 717-1, the Weighted Sound Reduction Index (Rw). CLiC. Window STC Rating Chart. Performance data is calculated using both LBNL Window 7. 0 This guide provides an introductory overview of glass concepts and terminology, plus Products. It’s essential to refurbish underperforming windows and facades. 29W b D3s trcQ C6 MKETIG@ For commercial-grade STC ratings, you could aim as high as 60, which is more than enough to reduce the sound in a firing range. This is primarily thanks to the air gap, which is a great acoustic insulator. When the worst−performing component occupies greater than about Technical Glass Guide Update 6/15/21 – Version 3. K = 40 for a player new to the rating list until he has completed events with at least 30 games K = 20 as long as a player's rating remains under For windows specifically, the addition of storm windows or the use of laminated glass can greatly increase the STC rating. Glass size and glazing system will affect STC rating. See more This AIS Glass’ software helps you to calculate the acoustic insulation & configurations like glass thickness, thermal breakage, etc. Read more about the tools below, or register and start using Glass Analytics now. Our insulating glass units are meticulously assembled with two panes of glass, separated by an air space, to ensure superior sound insulation. How to Calculate the Glass STC - Free download as PDF File (. A four-point STC improvement can cause a clearly perceptible change in your home’s acoustics, while a 10-point improvement can reduce sound by 50 percent. Configuration. *OITC is estimated based on this test. Select Product. STC Rating (Test) STC Rating (test) Artisan Series STC Ratings. 5lgM+13 R:Monolithic glass STC M:Glass density. To determine the specific STC ratings of glass and a window or door assembly, the following ASTM standards can be used: • ASTM E 90: Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions • ASTM E 1425: Acoustical Performance of Glass and Wall Constructions Overall Thickness Inside Construction Space Outside STC Value ISO RW 3 1/4" (7.
