All of our Free-Standing Portable panels are 8’ wide x 12’ tall. These panels are light weight and easily installed with a 3-man crew, (no equipment necessary.) The panels share a support leg on each side and can be setup in any configuration. The panels are then anchored into the ground with 1-inch iron rod stakes which are driven through the support legs and/or multiple 50lb. sandbags, to prevent the panels from blowing over. One inch angle iron braces are supplied and attached to the leg and panel for extra stability. The acoustical blanket attached to the panels are rated STC-25 and NRC- .08. The interior of the blanket consists of ½ lb. MLV (Mass Loaded Vinyl), which blocks the transmission of unwanted sound levels, and another layer of ½ inch open cell foam. The open cell foam allows 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. These panels can be rented daily or purchased.
