    Easy to install

  2. 5 out of 5


    The acoustical wave tiles were used in a bar restaurant in ***.
    The tiles added a nice design feature to the ceiling as well as doing their job of sound control.
    Simple to install and very easy to cut if you need to adapt to space.

    Product looks great after installed, but much more fragile that anticipated during the installation process. Had to wear cloth gloves because they get dirty very easily.
