Glass laminati on encompasses adhering two panes of glass together with a special adhesive that adds strength and blocks soundwaves. While no specific STC rating defines a partition as “soundproof” in an absolute sense, higher STC ratings generally indicate better soundproofing performance. What was one of the biggest mistakes I made when my house was built in 2011 through Meritage Homes in Austin, TX? It was on the lack of soundproofing on interior walls. While there isn’t a specific STC Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. High-STC-rated doors are essential for spaces where privacy, noise control, or productivity is a priority, such The STC rating chart provides a visual representation of the sound transmission class ratings for different materials, STC Ratings for Windows and Glass. A standard guideline is that a sound transmission class rating of 40 or above is adequate for most residential applications, where everyday speech can barely be heard through the partition. Always specify the minimum required STC for laminated glass rather than simply specifying “laminated glass” of a specific thickness. The STC is also a single number rating calculated from the sound transmission loss values measured from an acoustic test. 5” Acoustics Assembly Number: ISS-00 STC: 43 OITC: 28 Report No. Connect With Us.

The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to Tested under ASTM E90, panels caulked in place with wooden stops and glazing putty. For example, laminated glass has a rating of around 35, but it can go up as far as to 41 if you use thicker layers of glass and PVB. What are NR, NIC & STC? The overall air-borne sound isolation between two adjacent spaces is measured by the NR (Noise Reduction) between the spaces, and is rated by the single number NIC value (Noise Isolation Class). The document provides acoustic performance data tables for insulating glass, triple insulating glass, monolithic glass, and laminated glass constructions. Oftentimes, this medium is air. Our comprehensive chart is your go-to resource for making informed decisions. Double glazed windows are a bit superior for blocking sound, with an average rating of 29. S. Caution: You cannot add STC ratings. The higher the STC rating, the better the sound isolation. Today, an STC rating is one of the important standards of design for buildings, especially where the acoustics are a concern. Some have short/long-term adverse health effects. It includes STC ratings for commonly used materials such as: • Acoustic wood door and steel frame assemblies provide the broadest range of Sound Transmission Class (STC) ratings in the industry, tested in accordance with ASTM E-90 & E-413 • Acoustic wood door and steel frame assemblies are available in STC ratings up to & including STC 56.
