Thanks to Armand and others, I do have good ventilation with Styrofoam soffet vent "troughs" and roof vents. I can honestly say, my attic is a "COLD" zone. I will start working on the walls today and then the plastic. I have all but given up the metal ceiling idea now and will likely go with drywall all around. Lots of work, but the results will be worth it in the long run. Thanks again for the sound advice.

Metal s more expensive and cannot be patched or repainted easily. The goal is to ave the fiberglass itself in substantial contact with the vapor barrier. hen the vapor barrier is in contact with the insulatin, the moisutre vapor ends to diffuse upward through the insualtion and disperse out through the ttic ventilation, instead of freezing at any air pockets near the vapor arrier. you do have attic ventilation don't you? Don't forget to install wind wash barriers" between the rafters on the outside of the wall above he top plate. This will prevent the air from moving horizontally through he fiberglass and negating its insualting value exactly as the exterior all sheathing and cladding does. remember to install any flame producing eat sources (furnace) at least 18 inches above the floor to prevent gnition of fumes. iving in MN teaches you how to insulate a building. Insualtion is probably he most important thing after structure and life safety, as the building an be forever effcient and safe or leaky, moldy and costly to heat. ood luck rmand ----- Original Message ----- rom: "mike & sharyn klepp" <mask1966@xxxxxxx> o: <amc-list@xxxxxxxxxxxx> ent: Friday, January 07, 2011 12:35 PM ubject: [AMC-list] Garage Advice Needed AMCers, I know some of you have built garages to house and work on your AMC rojects and I need your advice. My garage is built (24 x 24) and I am in he process of insulating it now. I have the ceiling near done with R-25 raft-faced fiberglass. I plan to cover this with some sort of metal aterial similar to siding used on pole barns, etc. My question s.........should I cover the insulation with a plastic vapor barrier or is he paper good enough to avoid condensation on the metal from the heat ource. FYI, I live in central Illinois. If you have done something similar, I'd like to hear your comments, either ro or con, and how satisfied you are with the warmth of your own garage. hanks in advance.
