Mine is double-walled stainless steel. No glass.
I plan on having it the rest of my life. I love it. Put boiling water in it for a couple of minutes to pre-heat the carafe. Pre-heating makes all the difference in how long your coffee stays hot. Mine stays hot a very long time. 16 hours or so.
Double-walled stainless steel construction. DURABLE.
