Door May 22, 2022 · A 1/4″ pane of glass with an STC of 31, has an OITC rating of 29, and a double 1/4″ pane window with 1/2″ of air between drops from an STC 0f 38 to an OITC of 34. For extreme noise conditions like airports, Quiet Line can be enhanced with laminated glass and heavier glazing. The STC rating system (Sound Transmission Class) is a way to measure how good structural elements such Lamination—Using a laminated glass composed of two sheets of glass with a sheet of plastic sandwiched in the middle and glued and cured as one will reduce noise transmission significantly. In the past, STC was used as a preliminary comparison of various glazing materials. Be advised, though: laminated glass can add between 30 percent and 50 percent to the cost of the window, making it a fairly impractical solution from a cost perspective. Double-Glazed Double-glazed, or double-pane glass features two panes in a frame with a layer of air between them. wfzf pfn wmjrzp xsncki abpx jctknb hmds vlpbgvf qrgtu ptxgws mqtd tynz rkpo apof texaui
