Non-ESD mat, used with a ESD mat.

I recently bought a silicone soldering mat that has notches and grooves and it really helps with organizing my work space during projects (mostly phone repairs) . But I did some research on the mat and found out it was not ESD safe. So, my questions is that if I did buy a ESD safe mat, would it be okay to use the non-ESD safe mat on top of it.

In other words, ESD safe mat on the bottom, and silicone non-ESD on top. Would there be any static electricity generated.

Thanks, for the help. New.
