heating the garage

[jniolon@uss.com]

     I've seen the panel doors insulated with the foil backed insulation 
     board glued directly to the panels...I'm sure this adds "some" degree 
     of insulation but I would think the sealing the cracks and gaps around 
     the door would help much more...I think the wind blowing past the door 
     cracks would act as a very good chimney to suck out your hot air as 
     fast as you could make it...  but then again...there's no such thing 
     as too much insulation
