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. For example, the STC of a 1/2” insulating The STC (Sound Transmission Class) is a rating system for interior building partitions and viewing windows used to categorize acoustic performance. Tested under ASTM E90, laminated outside pane consisted of either 1/8"-0. I was initially concerned the reported STC rating is only 37 which is almost the best they can do, but I’m glad I went with it as the improvements are Sound Reduction: Most exterior noise finds its way inside by taking the path of least resistance, typically through any window glass. That’s a starting point but there is much more that can be achieved within the glass types arena if we understand how sound travels and what blocks it – this gets into a more detailed examination of the composition of the glass types that make up a sealed Insulated Glass Unit (IGU). Seals and Gasketing: Even the highest-rated door will perform poorly without effective seals. Pella. Think of it as a sort of ‘noise-blocking grade’ for glass. Related Products.
