ELECTRICS • Hard-Wired The ASTC rating is therefore a better descriptor for the sound insulation that the building occupants will actually experience. Nevertheless, the STC and IIC rating systems are advantageous from a building code / regulatory perspective because they provide a single-number rating that roughly correlates with subjective impressions of airborne sound transmission from sources such as human voices, radio and television, and structure-borne sound Sign in with your username and password. 1/4” (6mm) monolithic glass has an STC rating of 31 1/8” x . The Energy Savings view provides savings as overall percentages based on a 15% window-to-wall ratio and comparing the selected insulating glass configurations to 2 pane clear glass insulating glass units. Costing more than other materials, this is used mainly for exterior applications. The higher the STC rating, the less noise is passed through the material - in our case, the door opening. This gives some varied answers for sure, which is what is used as part of an average to give an official STC rating. Feb. VITRUM. The National Research Council of Canada conducted research on the importance of sound insulation, and found that an effective STC rating of 55 is recommended, and 60+ is ideal, especially in rooms where there is going to be music related noise. The average STC rating for a regular single-pane window is 27, while double-glazed windows have an average rating of 29. This rating is given to materials that are tested over a range of frequencies, and are proven to block sound in some capacity. If thicker glass material is used, the rating can go up to 35. OITC, on the other hand, covers a broader frequency range (80 to 4000 Hz), including lower frequencies often associated with external noise.
