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 The STC measurement has been around since 1961, so for a long time, that was the only rating to measure how windows performed acoustically, in 1990 the OITC measurement came about as a way to rate outside noise. Unless the entire structure is engineered for sound control, there is little value to purchasing windows with a higher rating than the wall. new rating to describe products that comply to the standard. Overall Glazing Thickness: Exterior Glass Thickness. Pella 2024 Architectural Design Manual Division 08 – Openings 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. 8215 Carter Creek Drive, Unit 203 Charlotte, NC 28227 704-200-2001 E-fax: 704-973-9568 Toll Free: 877-773-7379 Window Assembly published STC/OITC and U-Factor ratings of leading national wood window and patio door brands. 0 or less.
