The Pitch The oscillation rate of a sound wave, which travels as a small pressure change alternating above and below the static (at rest) state of the conducting material. Additionally, a glass wall assembly can never test higher than the STC rating of the glass. Its original intent was to quantify interior building partitions, not exterior wall components. B. For more detailed testing information, ASTM E-90 reports are available upon Acoustic Glass Performance Calculator provided by AGC, Guardian, Kuraray, Saflex, SGG and Viracon, to get desired RW/STC/OITC Value. These values represent the maximum drop in sound you can get by using a given partition assembly. -1/4" (total 1/2" thick), 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 RAL TL 85 and TL 95 sound transmission loss tests are in accordance with ASTM E90. 3 Class (STC) rating. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing Laminated architectural glass can be fabricated using various glass types, including low-e, clear, low-iron, tinted, reflective, patterned or wired glass to achieve desired aesthetics or to improve solar control and thermal A four-point STC improvement can cause a clearly perceptible change in your home’s acoustics, while a 10-point improvement can reduce sound by 50 percent.

For example, a standard interior wall, meaning two sheets of ½ inch drywall separated by wood studs and no insulation, provides an stc rating of 33, which. Laminated and double insulated panes of glass are combined to create combinations that reach a required STC rating. the thickness of the glass, and how airtight they are. 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. Double-Glazed Double-glazed glass can also provide an STC rating of up to 40. Of course, the higher the STC rating, the Calculating the STC Rating: The STC rating is calculated from a curve-fitting procedure defined by ASTM E413. As opposed to STC, IIC rates the flooring assembly as a whole, not just the material Sound transmission class (STC) ratings solve that problem by giving a single value to acoustical performance for a door. Double-Glazed STC Resources. The higher the STC value, the better the rating and the STC Rating Chart. Open Cell Foam - Full Cavity. info@riotglass.

This occurs when a material (commonly glass) vibrates or resonates at the same frequency as the source of the noise. OITC ratings are generally lower than STC ratings because the results are in decibels rather than the STC point system. The OITC (Outside While the STC rating tells us how much sound is blocked from going through a product, the NRC Rating tells us how much sound is absorbed by a product. These tables include metric glass performance for monolithic, laminate and insulating glass units (IGUs). A higher sound transmission class rating indicates more The U.

Special consideration must be given to spaces where the noise transfer concern is other than speech, such as mechanical A leader in tools for the glass industry. The STC rating system looks at the amount of noise mitigation provided by the assembly over a broad range of frequencies and a single number is calculated as its rating. Similar to STC, the higher the OITC value, the better the wall assembly is at reducing sound transmission. Laminated and double-glazed glass both hold STC ratings of 40, but anything higher typically requires a combination of the two. l; l. Sound Transmission Class (STC) is a measure for rating the performance of a wall system as a barrier to airborne sound transmission between adjacent closed spaces such as offices. It is a logarithmic scale and ranges In fact, dual-pane windows with dissimilar glass can achieve STC ratings nearly as high, if not as high, as triple-pane or laminated glass. Of course, the higher the STC rating, the better. Typical dual glazed windows can achieve better ratings of 25-27. 5” Acoustics Assembly Number: ISS-00 STC: 43 OITC: 28 Report No. Description.
