I have a 1/8 in almun y plate, what do I use for insulation ?

I’ve seen people use rockwool, or cork tiles but don’t have any specific experience.

You don’t need anything. The only reason I use it is hopefully a little energy efficiency since I have so many printers running in a cold garage.

Come on… You live in California! Your garage never gets as cold as I have my house set for in the winter. :slight_smile:

Pffffft it was alllll the way down to like low 60’s last night. I almost had to put shoes and socks on. Poor printers working in such harsh conditions all the time.
