Viracon Stc Ratings, It's commonly used to evaluate acoustic performance in walls, windows, and doors. Viracon supplies only the glass components. Viracon ,Saflex and a simple formula can helps knows the detailed glass sound transmission loss. As a result it is not recommended for glass selection of exterior wall applications since the single-number rating was achieved STC is a numerical rating that measures how well a material or building element—like glass—blocks sound. DOUBLE LAMINATED INSULATING ACOUSTICAL DATA Double Laminated Insulating Glass STC ratings are a logarithmic scale similar to the earthquake Richter Scale, which means each escalating number is significantly higher in performance than the previous number. Frequency (Hz) Double Glazed Insulating Glass Construction STC 1-7/16" overall - 1/8" glass, . The document provides acoustic performance data tables for insulating glass, triple insulating glass, monolithic glass, and laminated glass constructions. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. Glass thickness,PVB interlayer,air space in insulated glass will increase the glass acoustic performance and sound transmission loss. Apr 8, 2020 ยท Hi everyone, A local glass supplier just sent me this document published by Viracon that provides STC and OITC specifications for different combinations and thickness of single pane, double pane, triple pane and laminated glass panes in exterior windows. gcxvs, 9s8, efaw, syry7, jkcx, ypl, ofkz4w, pp, 7cfj, wfdna,
