I have a small ranch with an underneath garage. I recently discovered a leak inside the garage ceiling directly under the upstairs bathroom. The ceiling was opened up, and the broken pipe was repaired. Now the entire plaster ceiling must be taken down to get rid of the resulting mold. Before a new ceiling is installed, is there any reason I should put insulation there? I just don't want to miss an opportunity if it's a smart thing to do. The garage is heated with a forced-hot-water radiator. Thanks.
If you insulated the garage ceiling you could set the garage thermostat lower or off (be careful of letting radiator water freeze). Save energy while keeping the bedroom floor warm. The payback period would probably be pretty long though.
Use a product called THE BARRIER it is a vapor and moisture barrier as well as a thermal break. It is 3/8" thick EPS with a 3-mill poly-vinyl laminated on both sides. It comes on a roll and can be cut with scissors. To install you can staple the material up or use screws or washers to hang.
