Factors That Affect Your Glass STC Rating. Both achieve an STC rating of 40, but higher ratings require a combination. The higher Best Performing Laminated Insulating Glass Zero reported seal failures for 5+ years, compared to industry average of 2% yearly failure rate. Single-pane versus dual-pane versus triple-pane glass. If Laminated glass is two or more layers of glass permanently adhered to one another with one or more polymer interlayers in a thermoset, high-heat process. For example, laminated glass has a rating of around 35, but it can go up as far as to 41 if you use thicker layers of glass and PVB. Windows with single-pane glass are less common than they were 20 years ago, but they are still found in some older homes. For maximum acoustical needs, Cardinal recommends a double-laminated IG unit. Triple pane isn’t going to do much for the stc. 1/8" 36 36 3/8" (10. Minimal sound isolation, such as in non-critical residential areas. These windows are also large and small missile impact-rated and NFRC certified, making them ideal for coastal areas. However, sound transmission can be significant through ordinary glass. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing SF6 the overall STC rating of the glass can be improved by as much as 3 points. 2' x 4' beam traveling at 50 feet per second, followed by hurricane-force winds.
