I have an unfinished garage and I'm going to be drywalling it at some point this year. I'm also going to be insulating the walls. It won't help a whole lot since the roof of the garage isn't insulated, but I wanted to do it in case the next homeowner decides to insulate the whole thing. R-value, foil-backed, vapor barrier? [?] FYI, this is California. Warm summers (80-100+) and mild, wet winters (40-50). |

I used R-13 for the walls (standard 2X4 framing). I bought it in the bails, instead of rolls. It was easier for me to put up precut lengths. I bought an electric stapler to use as well. I also drilled holes for my power outlets before putting in the R13, then routed the 12-2 wire to the outlets and hooked them up. I went with 20amp outlets and a 20amp GFI. The R13 had a plain brown paper back with a lip on it to staple to the framing, it wasn't foil backed. I like the look of a finished garage, not to mention the benifits of insulation (temp, sound). I'm in the process of putting primer & texture on it now. |

I would urethane it but, that is more expensive. (I used to spray that stuff on roofs.) Don't use a vapor barrier or "poly" the outside of fiberglass or blown insulation. The condensation from the barriaer causes the insulation to rot, mold, or mildew. "Pink Fibergalss" R19 Paperback is more than adequate and is also affordable and easy to install. |
| When we re-worked Casa Arock three years ago one thing we did was rip out the garage drywall and insulate the exterior walls. House was built in 1972 and the plumbing in the walls was not insulated so I figured let's just start over and do the job right. Ceiling was already insulated as the garage is under the master suite but insulating attic space is very easy using either batts or blown-in. We live in north Texas and the garage wall faces west so heat transfer was a concern, but it'll be in the teens tonight. One routine had to be changed; our practice of parking hot vehicles in the garage in summer trapped too much heat inside. |

Quoted: Temperature activated exhaust fan. That would work. In my small town there's a company that rebuilds unified AC/heater units like you see in motels. I'm thinking about getting one of the larger ones to mount in an outside wall. For the time we park outside under the trees in summer and inside in the winter for residual heat capture from the vehicles. |

Did the insulation for the first wall today. It took me longer to clear all the crap away from the wall than it did to install the insulation. This is where all the free-standing shelves that held my ammo cans were.

Comes in 15" x 96" batts, plus some of the batts are perforated so you can easily trim them lengthwise for smaller areas.
