Signed Out

Looking for the best method of installing a 10'x5' coro sheet to a backlit sign. This is a temporary sign advertising office space, the backlit sign doesn't actually work as of now so no worries about the coro not being backlit. The existing sign panel is 3/16" polycarbonate. Was planning on grometting the coro around the perimeter and a few throughout the middle. I'm in upstate NY and it is cold, was planning on using self tappers and washers to hold the coro on, but am concerned that the polycarbonate might crack without a relief hole? Any thoughts or suggestions are greatly appreciated. Thanks,
