How It Works: The technology behind STC Glass involves combining dissimilar glass thicknesses to attenuate the noise to form the IG. If laminated glass is broken, the vinyl interlayer remains in the frame, with glass fragments adhering to the interlayer. However, it can be an effective component in a broader soundproofing strategy. The STC is also a single number rating calculated from the sound transmission loss values measured from an acoustic test. SH/SH or PW/SH or SH/PW 26 1/2 x 22 1/2 96 x 96 R20 Materials are given an STC rating in a lab testing environment, where sound waves are measured at different frequencies on both sides of the material. The other key advantage to 1″ (25mm) insulated unit, incorporates 5/16″ (8mm) FireLite Plus with 1/4″ (6mm) Tempered Glass. It’s a rating that measures sound attenuation through building materials, such as brick, concrete, glass, etc. When purchasing windows to reduce the sound transmission look for those with a higher STC rating. If this is a deal-breaker, consider laminating to avoid the distortion. Company. The higher the STC value, the better its insulation. These STC ratings represent common wall and door assemblies.
