Our Temporary Sound walls are typically offered in heights of 16′, 24′ and 32′ tall. The individual sound wall panels measure 8’ tall x 20’ long and are constructed out of 16ga, 2-inch square tubing. Each panel is then covered with a custom made acoustical blanket that is rated STC-30 and NRC-85. The interior of the blanket consists of 1lb MLV (Mass Loaded Vinyl), which blocks the transmission of unwanted sound levels across the frequency spectrum, and another layer of WhisperDri™ SANWF, (Sound Absorbing Non-Woven Fiber.) The WhisperDri™ insulation is a proprietary blend of synthetic fibers that allow noise to be absorbed into the sound wall and prevents it from being reflected back into the job site. The exterior of the blanket is covered with a gray vinyl UV-protected shell which faces away from the noise source and a vinyl mesh screen facing toward the noise source to allow for noise absorption. All materials used in the construction of the blanket have a superb FR rating.
