VLam™ Hush Acoustic laminated glass Features and Benefits • 6. The acoustic attenuation of a 6-12-6 mm glass is generally superior to that of a monolithic 6mm-thick glass, but only by 2 or 3 dB, and still there may be low frequency bands where the DGU performs worse. It can also be incorporated into double-glazed units fabricated from inorganic glass fibres. TRIPLE PANE INSULATING ACOUSTICAL DATA. The configurations are for single glazing with Window Energy Ratings were originally launched in March 2004 by the British Fenestration Rating Council (BFRC), an independent government-supported body established to develop and administer a system of Window Energy Ratings in the UK. I recently worked with a client who wanted acoustic solutions for a drum set. Triple Insulating Glass Construction Frequency (Hz) Glass size and glazing system will affect STC rating. A good OITC window rating is 30+ and usually comes with thicker glass (½” or more) and added glazing for Sektor 90 Double glazed I-line joint 1 x 12. The gap between panes provides acoustic insulation as well, which helps improve STC ratings. 08kg/m2 Other types of acoustic glass are available and can achieve Rw values up to 58 decibels. 8mm acoustic laminate glass + 1 x 12mm toughened glass - 48dB Sektor 90 Double glazed I-line joint 1 x 12.

Email: info@commercial-acoustics. Just as we were in 1932, we're ready to meet the challenges of now and the future. *OITC is estimated based on this test. How effective is Acoustic glass? The performance of acoustic glass will Laminated glass can have STC ratings of 40 or more. The software is able to calculate the the acoustic insulation provided by a particular glass type and configuration. The first step in rating a product is to determine the transmission loss of the material at various frequencies. Its original intent was to quantify interior building partitions, not Equipment for glass transport and storage; Warm edge spacer bars TGI Examples of acoustic test reports - double glazing Examples of acoustic test reports - double glazing Double glazing: 4 - 20 argon - 4 Rw = 31 dB; Double glazing: 6 - 16 argon - 4 Rw = 34 dB; 1-7/8" overall - 1/4" glass, 1/2" airspace, 1/4" glass, 1/2" airspace, 3/16" glass, . Learn why STC ratings matter for soundproofing. What Is an OITC -114• glass) with an STC rating of 34. For example, the sound of a whistling bird (50dB) is stronger than the sound of a falling As a general rule, where single glazing is used, the acoustic performance of the glass improves as the thickness increases. Selection of suitable glass involve using thicker glass, VLam™ Hush means that thinner and lighter glass can be used for equivalent acoustic performance. It can also be incorporated into double-glazed units Does Acoustic glass offer any other benefits? Yes, the fact that acoustic glass is a laminated glass also gives the advantage of safety & security to your home. Address: 6301 N Florida Ave Tampa, FL 33604 The glass delivers a Sound Reduction Factor (Rw) of up to 54 decibels (dB) in triple glazing and 52dB in double glazing. 52mm 12mm glass x 1. Factors That Affect Your Glass STC Rating. A higher sound transmission class rating indicates more effective sound insulation than a lower rating. DUAL All values shown are glass only. This is Figure 1: Sound Transmission Loss of Laminated Glass with Saflex® Q series acoustic interlayer and Saflex ® R series interlayer. 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. This performance data is not a commitment for Cardinal to produce. 76mm/12mm/4mm float glass Double glazed units with acoustic glass on the exterior pane 40 30. archskirt. Data is based on testing ~36" x 84" glass to ASTM E413-87 in an acoustical wall. Registered Office: Double glazed systems allow you to accommodate different thicknesses of glass, so a wide range of acoustic ratings can be achieved. However, architectural acoustics can often become a bewildering array of alphabet soups (STC, OITC, and IIC, to name a few!), and even acoustically experienced architects and designers can be left scratching their heads. Try now our easy-to-use, advanced software for glass and glazing system analysis. Acoustic glass, also known as soundproof glass, or noise reduction glass is specialist glass installed in noise reduction windows that can reduce the amount of noise that is transmitted through the glass and a window (or door). Outside-Inside Transmission Class (OITC)—measures sound transmission of low- to mid-frequency noises through exterior Figure 1. Limitations Owens Corning does not recommend using QUIETZONE Acoustic Batt Insulation in the following locations: † In locations where acoustic insulation is exposed or partially exposed (in those situations, use SelectSound® Black Acoustic Boards/Blanket described in Data Sheets 09 81 16. Except for the acoustic properties, light properties, energy properties, thermal properties, safety properties, and Acoustic glass offers superior noise reduction and soundproofing. 5mm VLam™ Hush achieves the same acoustics compared to 10. Glass size and glazing system will affect STC rating. The BFRC is run by the Glass & Glazing Federation (GGF) the trade body representing many window companies. Laminated and Double-Glaze Glass Combinations: Combining laminated and double-glazed glass is best for ideal soundproofing. Guardian Glass is a leader in tools for the glass industry. The higher the dB rating, the stronger the sound. Companies are developing specialized acoustic glass products with advanced interlayer materials and thicker configurations to achieve higher Sound Transmission Class (STC Laminated panes’ STC ratings typically provide and STC rating reaching high 30s depending on the thickness of the glass and adhesive. 030″ Acoustic PVB / 3. 5 times over normal glass. STC is determined by a weighted average of TL values taken over 16 frequencies, which are fitted to a curve in a method defined by the ASTM E413 Classification Standard for Rating Sound Insulation. STC ratings are predominantly used in the United States. At Komfort, acoustic performance is a key element in the design and manufacture process of our acoustic glass partition systems. Noise Reduction Solution Charts Values are center of glass calculated using LBNL Window 7 per NFRC100 conditions. 05.

Of course if we compare a 6 mm-monolithic with a double glazed 6-12-6 mm, Acoustic laminated is a high-quality laminated glass with a PVB (polyvinylbutyral) acoustic interlayer that considerably reduces noise. com. Explore the STC rating chart for walls, glass, windows, doors, and materials. Report: TL723-02-01 FIRE RATING • Fiberglass insulation is inherently non-combustible because it is made from mostly sand and recycled glass and requires no additional fire-retardant or treatments. While STC rating can provide a good indication of how a material or product will perform against sound in general, it isn’t Acoustic ratings are determined in highly scientific laboratory tests, but we can focus on two critical elements that are always looked at: frequency, which is measured in hertz (Hz), and decibels (dB). Simply put, STC ratings measure sound level on one side of a wall, versus the other side of a wall. info. Technical Glass Guide Update 6/15/21 – Version 3.
