Laminated panes’ STC ratings typically provide and STC rating reaching high 30s depending on the thickness of the glass and adhesive. The order of sound insulation performance from poor to excellent is: Gaps or weaknesses in the frame can compromise the STC rating. Solar Heat Gain Coefficient (SHGC) is the sum of the solar direct What Do STC Results Mean? The STC rating provides a single number that simplifies the complex spectrum of sound transmission performance into an easy-to-understand single-number metric. The STC rating system looks at the amount of noise mitigation provided by the assembly over a broad range of frequencies and a single number is calculated as its rating. Calculation Example: The sound transmission class (STC) rating is a measure of how well a wall or partition blocks sound transmission. The estimate could easily be off by as much as +/- 4 dB. Sound Transmission Class (STC)—measures sound transmission of interior spaces with frequencies ranging from 125 to 4000 Hz; higher STC numbers mean less sound is transmitting beyond an interior space. Like the STC rating System, OITC measures sound intensity loss in decibels. Glass weight estimator tool. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to Search for suitable solutions based on glazing parameters and acoustic requirements. † Based on Stats Canada Report CS44-004-IN, April 2013 to provide conservative estimates of required STC or Rw ratings to be used by the building designer as a planning tool for window glazing. . 30% OFF Explore All Deals | Call Us: (866) 452-7707.
