TEST NUMBER STC OITC 6mm Temp. STC and OITC requirements are increasingly common for projects; using laminated glass is a great way to meet those acoustical requirements. The blares and beeps of heavy traffic, the roar of airplanes, and the rattle of trains all produce a low-frequency cacophony. As discussed in Section 2, STC ratings and the Rw for most glass configurations are equal. com Page 1 of 2 www. Laminated glass also provides 99% UV light blockage and can improve sound transmission control (STC) and Outdoor/Indoor Transmission Class (OITC). The numbers you get on these will give the amplitude of sound, which is reduced by the glazing, which is why you should go for the highest number as long as it can be afforded. ASTM E 413. Support for 2D/3D Libraries and BIM Models Aug 10, 2021 · The presence of glass; The STC/OITC rating of the door; Plastpro has compiled detailed explanations about soundproof doors, the two testing classes to keep in mind, as well as more information to help you choose the best soundproof doors and find where to buy them.

Factors That Affect Your Glass STC Rating When it comes to designing a building,thermal insulation performance is the most important consideration. The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. 24 Page 1 of 2 Due to continual product research and development, details listed are subject to change at any time Laminated glass is also available with tinted interlayers in clear, bronze, grey, or green. Sound transmission class (STC) and Outdoor/Indoor Transmission Class (OITC) are measured in decibels (dB), and are the standard method for rating sound attenuation characteristics of glass products and window assemblies. STC ratings are the ONLY way to accurately compare various noise reduction products. GAP GLASS CENTRE GAP GLASS INT. You can choose tempered glass, laminated glass, and STC/OITC glass for specific windows and rooms. Glass 1 Spacer Glass 2 STC OITC Sound Transmission Class (STC) - The STC rating is a single number value quantifying the ability of a material to resist the transmission of sound. The side-light glass panes (2 side-light openings) were 800 mm (31 ½ inches) wide by 208 cm (82 inches) high. Sep 4, 2018 · A product may have a great STC or OITC rating, but struggle with dampening a particular noise frequency. Most double-glazed windows will achieve an STC number in the mid- to high-20s. 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. The higher the rating the higher the resistance to sound transmission.

PRESS GLASS possesses North America certification for sound absorbing glass with an acoustic insulation factor STC ranging between 33 dB and 52 dB. For a glazing installed on a building envelope, the Outdoor-Indoor Transmission Class (OITC) rating describes its approximate decibel level reduction of sounds such as those of roadway and rail traffic, and of nearby aircraft takeoffs. Laminated glass also has a thick interior pane with the interlayer. The OITC covers a wider range and lower frequency than the STC. Sound Transmission Class and Outdoor-Indoor Transmission Class Glass has increased pane thickness, ideal in areas where exterior noise is a concern. Is the new product vinyl?? F F Windows and doors can help block outside noises whether you live in the city or on a farm. Laminated glass consists of two or more layers of glass that are permanently bonded together with one or more polymer interlayers using heat and pressure. Q: How does it affect a unit's performance (NFRC values, STC/OITC, etc Dec 31, 2024 · Unlike STC, OITC testing specifically accounts for low-frequency noise, which is often more challenging to block due to its ability to travel longer distances and penetrate barriers more easily. transportation noise reference spectrum. com PRODUCT . Feb 22, 2024 · The OITC is a newer rating system similar to STC that was designed to measure sound transmission loss between a more extensive frequency range from 80 to 4000Hz. One thing that I’m not clear on: how would I know how high of an OITC rating I need? I’m guessing that I would use a sound/decibel meter to measure the undesired noise, estimate a desirable/tolerable noise level (in decibels), and calculate the difference (bad noise decibels minus good noise decibels, if you will). 060" PVB, 1/4" glass Laminated Glass Construction STC OITC 100 125 160 00 2 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 The enclosed STC and OITC data is for insulating glass constructions only.

For both measures, the higher the Nov 25, 2022 · Glass thickness; Number of glass panes; Spacer type; Insulating gas Any of these factors, alone or in combination, can have an impact on the STC rating and performance of your window or door. STC Sep 14, 2021 · OITC is calculated by subtracting the logarithmic summation of the transmission loss values from the logarithmic summation of the A-weighted transportation noise reference spectrum stated in the calculation standard. However, it was developed to evaluate sound transmissions through exterior walls to determine the performance of a product about exterior noises. Our specialty options include glass for unique project needs like sound abatement (STC/OITC), high altitudes, Sea Turtle Conservation Codes (available on Signature Ultimate products), and California fire zones. The final STC/OITC rating of the window assembly could vary because of the influence of the framing members and the construction of the window assembly. Apr 19, 2022 · 我国采用Rw标准（ISO标准），欧美国家多采用STC标准，同一块玻璃的STC值等于或略小于Rw值。而一般说的门窗玻璃的隔声量指：计权隔声量Rw+交通噪声频谱修正量Ctr值。（如下图） 一、人耳的听觉. It is more durable than tempered glass and is often referred to as impact-resistant or safety glass. What OITC Can Tell You About Your Windows Because it weighs low- to mid-frequency sounds more heavily, OITC is a more appropriate rating System for Windows. All laminate Outdoor-Indoor Transmission Class (OITC) – applicable to exterior walls (including doors and windows) where the sound source is due to transportation vehicles (cars, trucks, trains). GLASS EXT. It disrupts the transmission of sound to reduce its impact. 0mm: Double strength glass 5. The attached STC and OITC data is for glass only and that the final STC rating of the window assembly could vary because of the influence of the acoustical performance of the framing members and the construction of the window assembly. 03mm transparent polyvinyl STC and OITC values are determined in accordance Unlike STC and OITC glass, PVB laminate is a relatively new addition to the Infinity from Marvin family.

Slight possibility you can change out the glass packs to the sound proofing version, however. Sound Transmission Class (STC) is a single-number rating of the airborne sound transmission loss (TL) performance of a constructed assembly measured at standard one-third octave band frequencies. com Page 1 of 1 www. 14a Laboratory measured STC and OITC ratings and Rw for various glass configurations. Doors STC Range* OITC Range* M600 Terrace Door 34-38 30-33 *Ranges shown are the result of multiple tests performed using various types of glass thickness. For example, the STC of a 1/2” insulating glass unit (3mm/6mm airgap/3mm) is 28 and the STC rating of a 3/4” insulating glass unit (3mm/13. In this test, the outboard lite simply was increased from 6 to 8 mm (1/4 to 5/16 in. values of insulating glass constructions. What type of door material is best for soundproofing? Wood Doors Dec 31, 2016 · The test exhibited laminated glass resulted in the best transmission loss (TL) contour and STC, but not of the OITC due to a coincidence dip at 125 Hz (Mediastika et al. * Aug 21, 2024 · The variation in glass thickness between the panes breaks sound waves into different frequencies. When a product is tested, the transmission loss is recorded in multiple frequencies, as the entire sound spectrum is tested, which helps to pinpoint to provide conservative estimates of required STC or Rw ratings to be used by the building designer as a planning tool for window glazing. Notably, road noise is a lower frequency sound, so depending on the proximity to busy streets and interstate highways, it is important to consider the OITC rating and look for higher numbers. Both STC and OITC ratings inform your window or door selection based on sound insulation Oct 14, 2014 · In the case of both STC and OITC ratings, a higher the rating, the better as it indicates that less noise is detectable. tubeliteUSA.
