I won't be home until tomorrow night - in Hawaii now - but it's been down in the teens for temps at home. As soon as I land - I'm going to take the digital infrared temps of the tool boxes... will be interesting to see how that temp has held up with the big drop for over a week. Nobody has been there so the doors have all been closed etc. I did leave all the lights on so will be an interesting "test". The tool boxes measured 71 degrees a couple weeks ago - but the outside temps then were in the low 50's at night and mid 50's during the day.
OKAY - it's been 20's for more than a week... just got home and measured the tool box temps - 60 degrees right on the nose... Not a bad drop in temps for a week of 20 degree temps outside... and only lights for heat. If it stays cold - I'll kick in the 220v heater.
Wayne -- Don't have a name for it - but it was called High Density Bats... and the walls are 6" thick -- and the walls are packed full! Let me post a pic here - back in a couple - have to transfer the pic to the Photobucket and then post up here...
This was when they were putting it in... I don't think there is "paper" on any of it.. it's just big soft bats of this fiber stuff...
When they finished the ceiling - they stapled white plastic on the "inside" of the purlins... to keep the moisture from rising up and condensing on the inside of the metal roofing. I covered the interior walls with 5/8" plywood to the 14' mark...
TWO important parts of the insulation ----- it's WAY warmer in the winter -- and WAY WAY cooler in the summer (leave the doors shut!)... Can't imagine what it would be like out there in the summer without the insulation... and no way would I be out there ENJOYING MYSELF in the winter without it! So as thing go - IMHO - the insulation "made" the shop.
insulation insulation.... i have (im sorry to admit) a used engine oil powered stove... it gives off a nice dry heat as all the smoke goes thru the chimny...
ill take measurements and send post pics if anyone is interested in building one... it is very low tech.. but works great, and its cheap to run...and it could be made in a day by anyone with a welder and a powerdrill...

The 6" give you a nice continous run of insulation.
When I finnally get started on my garage, I'm going to use 2x6 for the walls like I did in the house. I would like to get spray foam insulation but its expensive.
heres what i bought. I went electric because i hate breathing in fumes while my shop is closed up. Just for example on its ability. My shop is 2600 sq. ft with 20 foot ceilings and no insulation. At about 40-50 degrees here in the bay area it will take the nip out of the air in about 30 min. Im positive it would make a shop 1000 sq ft or so really toasty in not time and its not very loud which is nice too. they are pricey new but i got mine on craigslist for a couple hundred bucks used and it works great!
