Guardian Glass Stc Ratings, Acoustic rating can be used to measure sound insulation of building elements and varies depending on the region of the world. Read more about the tools below, or register and start using Glass Analytics now. . 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. A leader in tools for the glass industry Guardian Glass has developed easy-to-use, advanced software for glass and glazing system analysis. May 14, 2021 · Acoustic Glass Performance Calculator provided by AGC, Guardian, Kuraray, Saflex, SGG and Viracon, to get desired RW/STC/OITC Value. Sep 17, 2025 · The STC (Sound Transmission Class) of glass measures how well it blocks airborne sound. SC Business Opportunities Welcome to the SC Business Opportunities database You must be a registered vendor in the state of South Carolina to bid on government solicitations. Ratings vary by type: single-pane glass is around 26–28, while laminated or acoustic glass can reach 40–50+. LAMINATED ACOUS ICAL DATA INSULATING LAMINATED ACOUSTICAL DATA DOUBLE LAMINATED INSULATING ACOUSTICAL DATA Double Laminated Insulating Glass Glass Acoustical Information also by the framing members and construction of the window assembly. Tip: Search results will appear according to the bid The Guardian Glass Performance Calculator, part of the Glass Analytics suite, helps you model and compare glazing options for your projects, from thermal and solar performance to acoustics, embodied carbon and overall glass performance. It is a non-linear scale. Discover vacuum insulated glass (VIG): a slim, high-performance glazing solution that helps reduce heat loss, noise, and embodied carbon. Quite simply, the higher the rating, the better the product. • You can check to see if you are a registered vendor here. • If you would like to register to become a vendor visit the vendor registration portal to get started. For glazing that is installed within a building interior, the Sound Transmission Class (STC) rating may be a more appropriate measure, as it describes the approximate decibel level reduction for the sound of human speech. One US glass manufacturer who has published STC ratings for their various product types are the high-performance glass experts at Viracon. Choose a glass configuration that balances acoustic performance with structural requirements and design preferences. The Guardian Glass Performance Calculator, part of the Glass Analytics suite, helps you model and compare glazing options for your projects, from thermal and solar performance to acoustics, embodied carbon and overall glass performance. For example, Rw is used in Europe while OITC and STC ratings are used in North America.
