I was at Home Depot and I was looking at the woodstoves, curious to see secondary combustion tubes. Its a neat setup, But I was wondering do alot of the new stoves have a styrofoam looking baffle in them? I know its not styrofoam, but I expected maybe to see some steel for the baffle and not this light stuff. Seems like its not too safe. If someone could let me in on it I'd appreciate it. I think it heats 2000, or 2200 square feet.
