How to protect barrel tile openings from embers?
I have heard that barrel tile should be "covered" to prevent openings for embers to enter during a fire.
What I want to know, what is used, and where do I get it?

Bird stops are what the plugs are called to fill those gaps, they should be available from the tile manufacturer. Mortar can work as well. See page 8 of this document for more information: https://disastersafety.org/wp-content/uploads/wildfire_florida-guide.pdf
