Products versus Spaces Glass size and glazing system will affect STC rating. GLASS OPTIONS • 10 and Marvin offers many glass types for your windows and doors, including insulating options and surface coatings, giving you energy efficiency for your home. This measures how much sound a substance can block. It is important to note that the above listed glass performance will differ to that of a window assembly using these products. Of course, the higher the STC rating, the better. Historically, professionals in the soundproofing business have relied on the STC rating system. It is an International Organization for Standardization (ISO) rating and part of the ISO 140 (Acoustic) family. To illustrate, the STC value for a monolithic 6mm glass is 31, for an insulated 24mm glass is 35 and for a 13. As a result, it is not recommended for glass selection of exterior wall applications since the single-number rating This table compares Vitro Architectural Glass product performance data when assembled in a one-inch (25 mm) insulating glass unit with a ½-inch (13 mm) air space and two ¼-inch (6 mm) lites. 43 - 44. Beyond the type of windows you select, other factors can affect the STC rating of your glass. Glass size and glazing system will affect STC rating. com. There is plenty of information out there at our fingertips, but it's important to get a full picture. A STC requirement of 35 is common for construction near airports – therefore a STC rating of 35 or greater would qualify. Sound Control: Reduces sound transmission through exterior and interior walls, floor and ceiling assemblies. Double-Glazed Back to STC ratings and how they relate to windows: Most windows are thermal and they are made up of 2 pieces of glass (usually 3mm thick) separated by a spacer. The higher the STC rating, the less noise is passed through the material - in our case, the door opening. 1. Design and optimize glass projects with AGC's Glass Configurator tool, featuring drag-and-drop components, performance reports, and connectivity to other AGC tools. Select Product. The TL of double glazing is strongly dependent on the features of the cavity between the two layers of glass. Thus, NIC is a more comprehensive Our new tool allows you to easily find and sort door selections based on STC rating, fire rating, glass size, and more. When it comes to designing a building,thermal insulation performance is the most important consideration. STC is often used to assess a number of different types of barriers, including windows, doors, partitions, and exterior and interior walls. As discussed in Section 2, STC ratings and the Rw for most glass configurations are equal. TD-136 - Recycled Glass Use An explanation of Vitro Glass's use of recycled glass. GLASS TYPE What Are STC Ratings?Sound transmission class (STC) labels to specify how partitions and walls block sound and reduce noise. 38 - 40. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing 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. Its original intent was to quantify interior building partitions, not exterior wall components. It’s STC rating (Sound Transmission Class rating) is a score given to a building’s surface (wall, ceiling, window, the thickness of the glass, and how airtight they are. Focus offers a tailored approach to specific environments with its acoustic and visual continuity, and matching wall and door pairings.

Address: 6301 N Florida Ave Tampa, FL 33604 STC rating – A material’s sound transmission class (STC) rating informs you of how much noise it can effectively block. The average STC rating for a regular single-pane window is 27, while performance of the window frame, the fi nal STC rating of the window assembly could have no infl uence to a 3-point drop in STC ratings from the base glass STC rating. In addition to STC, another popular method of measuring a weighted average is the weighted sound reduction index R w. To determine the specific STC ratings of glass and a The STC (Sound Transmission Class) is a rating system for interior building partitions and viewing windows used to categorize acoustic performance. Using either partition sound transmission loss chambers or floor-to-ceiling chambers, an acoustical testing consultant will analyze the attenuation, Calculations and terms in this report are based on NFRC 2010. *DH numbers are based on actual test results. The Sound Transmission Class (STC) is a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. The monlithic glass is one lite of glass. Glass surfaces are counted from the exterior face of the building. It is manufactured by permanently bonding two or more lites of glass with layers of polyvinyl butyral (PVB) interlayer, under heat and pressure, to create a single construction. Measure the sound in the adjacent room: Then, go to the adjacent room and take a second recording of the number The difference in sound levels is used to calculate the STC rating.
