Raising Ambient Temps?

[GiddyGoat]

I have 0 experience with faunariums, but have received plenty of advice to insulate my glass Exo-terra terrarium. So perhaps some sort of insulation. I'm sure someone more experienced will chime in. I'll assume you have a heat mat on a thermostat?

EDIT: if you're curious about the CHE, worked perfectly for raising the ambient temps in my glass terrarium.
