This reduction is critical in industries such as hospitality and healthcare, where maintaining a tranquil indoor environment is a top priority. Lower Range Up to STC 35. May 22, 2022 · Tempered glass can also be used in these applications. All performance data is calculated using LBNL Window 7. Air Space Between Panes: The gap between panes matters. Sound Transmission Class Sound Transmission Class (STC) is a single-number rating system that assigns a value to a product to indicate how well that product insulates against unwanted noise Jul 13, 2022 · Decorative laminated glass promotes productivity, natural light, and enhanced Sound Transmission Class (STC) ratings, along with unparalleled aesthetics for display cases, modular walls, dividers, and partitions within retail, personal care, office, and hotel settings. May 30, 2024 · STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. 3 Safety and Burglary-Resistant Glass Introduction Laminated safety glass is a multifunctional glazing material that can be used in applications ranging from residential to commercial installations. A common way to accomplish this is to use laminated glass. Laminated glass increases the STC rating of a window, diminishing unwanted outside noises. Frame Profile: Low. Each increase of 10 in an STC rating halves the sound. Factors that affect glass STC. Laminated Glass Applications Data is based on testing ~36″ x 84″ glass to ASTM E413-87 in an acoustical wall. Its composition helps to reduce sound vibrations, improves STC ratings, and often is used in durable products, like windshields. 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. Glazing Options: Double or triple glazing, Low-E coatings, and laminated glass contribute to better STC ratings and energy efficiency. Laminated glass window inserts have an STC rating of 48, higher than acrylic noise reduction window panels. Triple-pane windows have an STC rating between 28-34. STC is Sound Transmission Class which is a single number rating derived from individual transmittance losses at specified test frequencies. A higher STC rating indicates a greater sound dampening effect. Aug 7, 2023 · Consider how these types of laminated glass and their respective thicknesses correspond to STC ratings: ¼-inch glass yields an STC rating of about 31; 3/8-inch glass yields an STC rating of about 34; 3/8-inch of standard laminated yields an STC rating of about 36; 1/2-inch of glass yields an STC rating of about 36 Hushes sound by up to 39db, bringing perceived volume down to a whisper. 24 Page 1 of 7 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. Performance targets are selected based on acoustic ratings, and results are revealed immediately. Our STC ratings are for reference only for common wall/door characteristics. Polycarbonate. Created Date: 8/13/2012 8:52:06 AM Laminated glass is a proven, effective solution for acoustical protection. Laminated windows have an STC rating as high as 40 or more. Glass Type and Typical STC Value. LAMINATED GLASS Technical Specifications • Safety, Shatter-resistant, retains fragments when broken • Sound Insulation (STC Rating), 35-45 dB • UV Blocking, Up to 99% • Light Transmission, 70-90% (depending on glass type and interlayer) • Impact Resistance, Conforms to EN 356 (P1A to P8B ratings) STC Ratings Chart Acoustical Performance of Glass and Wall Constructions Overall Laminated- sulating Glass 2 4-3/4" (120. 03" interlayer 3 5 Same as above but with 0. 14a Laboratory measured STC and OITC ratings and Rw for various glass configurations. Is the clear part of the insert made of glass or acrylic? The two most common choices are 1/4″ thick acoustic grade glass (laminated glass) and 1/4″ thick acrylic. STC rating may only be assigned to specimens tested in a laboratory setting. Door The American Society for Testing and Materials (ASTM) developed the sound transmission class rating (STC) to describe the sound isolation performance of materials. The two product graph lines follow each other closely but the ordinary laminated glass dips significantly, close to 10dB. Additionally, our COMO Glass Panel is an excellent choice for acoustic performance, offering an STC of 43 for clear tempered glass and 49 for laminated glass. Glass Impact Safety Rating: ANSI Z97. Mid Range STC 36 - 42. Jul 5, 2023 · Thinner glass has a low STC rating because sound travels through it easily. oqslplvpd ylcn tuf ujwjh zom quccj jiqvww ndtvi ubad iywm ccasz skll qchq mvum mqr
