So are you telling me you use a kerosene heater in your shop? I see a heater in your pic that could be one. I have read in other post after starting this one were people seem to be okay with kerosene heaters. But I don't know if they are talking about the sealed electric kind or the kerosene burning kind.
In a shop that I built several years ago I had a fan like yours and they do work great.

I have been looking into insulation for metal buildings and these guys seem to have the best product at a reasonable price. http://www.insulation4less.com/Insul...l-48-Inch.aspx I was going to start another thread and ask if anyone has used it but I guess I will first ask here to see what kind of response I get. With the aluminum you also get the benefit of more light which I need.
