The Sanford, Maine post office is listed on the National Register of Historic Places and it's now home to the latest in ACRYLITE® protective barriers. The barrier is made out of .236” MR2 coated sheet. The employees love the way it looks and feel much better with an application like this in place during these unprecedented times.
In the images below, you can see the sheet with the masking still attached as well as after the final install.
