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). Laminated & Double-Glazed Glass. 5 23. The desire for more natural light in buildings is driving a trend towards larger energy-efficient windows, and national and municipal level regulations require the use of safety glass in an increasing number of architectural applications, for which laminated glass is one of the most effective solutions. Stc ratings chart acoustical performance of glass and wall constructions overall thickness inside construction space outside stc value iso rw 3 STC rating, the more able the material is to resist the transmission of sound. That’s where the Sound Transmission Class (STC) rating for glass comes into play. When planning glass wall systems, here’s a Graph 1 shows the sound transmission loss of glass across a low to high frequency range, comparing ordinary laminated and Acousta™ laminated glass. 1/ 0. 030 P. Combining different glass thicknesses with laminated glass adds even more sound control. -1/8" (total 1/4" thick), 1/4"-0. 3 safety glass: tempered glass vs laminated glass 1. Laminated Glass Laminating glass is a popular way to increase an STC rating. Acoustic Doors Designed specifically for soundproofing, acoustic doors have the highest STC ratings Some STC ratings of common window assemblies are listed below. What is the STC rating of 12mm glass? I upgraded street-facing windows to Milgard Tuscany dual-pane with laminated glass on inner side. Discusses the acoustical properties of glass, methods of rating, such as STC and OITC, applicable standards and the relationship between glass and other glazing components in determining an overall rating.

As The laminated glass industry has established standard designations for conventional laminated glass. -1/8" (total 3/8" thick), 1/4"-0. 38 32 6. This means one pane of glass is thicker than the other. The best sound reducing windows have dissimilar laminated plates with a wider air gap between the glazing. Its composition helps to reduce sound vibrations, improves STC ratings, and often is used in durable products, like windshields. 76 33 8. 5 mm 3 mm 33 28 6 mm 6. Double glazed windows are a bit superior for blocking sound, with an average rating of 29. 38 34 • Custom laminated panels use a 0. In addition, the stiffness of SentryGlas® is up to 100 times greater than PVB. In both laminated and double-glazed glass, the STC rating is 40, but anything higher calls for a combination of both. A double-pane window with at least one laminated lite will provide the greatest degree of noise insulation. VT Door Types . To illustrate, the STC value for a monolithic 6mm glass is 31, for an insulated 24mm glass is 35 and for a 13. Data is based on testing ~36″ x 84″ glass to ASTM E413-87 in an acoustical wall. Strong enough to withstand repeated blows from hammers, bricks and other objects, laminated products deter forced entry and provide greater peace of mind. By comparison, a ¼” laminated glass has an STC rating of ~34 dB. 0 mm 3 mm 31 26 3 mm 19. Laminated glass is like the windshield of your car.

As a result, it is not recommended for glass selection of exterior wall applications since the single-number rating As a result it is not recommended for glass selection of exterior wall applications since the single-number rating was achieved under a specific set of laboratory conditions. A common way to accomplish this is to use laminated glass. 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. Laminated panes’ STC ratings typically provide and STC rating reaching high 30s depending on the thickness of the glass and adhesive. laminated glass is considered “safety glass” because it meets the requirements of the various code organizations that set standards for safety. 1 introduction 1. However, Acoustical properties of tested glass constructions chart is attached. Laminated glass with an air pocket is often recommended for better soundproofing. pdf - Free download as PDF File (. g. STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. OITC, on the other hand, covers a broader frequency range (80 to 4000 Hz), including lower frequencies often associated with external noise. 52mm laminated glass is 39. • SL45 with STC 40 laminated glass has an STC of 36.
