Re: adding insulation to garage roof
said by liverdude  :the garage has a finished roof which I assume is insulated. The garage is not heated so it will drop in temperature during the winter. First, don't assume anything. Check and make sure it's insulated. If it's not, that's your first problem.
Adding insulation isn't likely to make it much warmer. Heat rises. The Garage is unheated. Connect the dots. Insulation is designed to prevent heat transfer, but it won't add additional heat. The bedroom has 3 outside walls which also contribute to the problem.
Also, don't compress the insulation. It won't make it perform better and will actually reduce it's R-Value. |

| Are you saying I should look at the walls before the floor/garage ceiling?
I'm going to cut into the ceiling this weekend before I do anything and make sure that there is something in there.
I can only imagine that the floor is the reason for the cooler temps in the bedroom.
We just had new windows put in and the ceiling above the roof has blown insulation and we are going to have more put in because of the rebates offered out here pretty much pays for 80% of the costs.
The walls don't feel overly cold so I can only guess that the floor is where the temp change is occurring.
I figured as much about compressing the insulation but was not completely sure that it would do anything. |

I did absolutely nothing.
I had a buddy come over who is skilled at doing such projects as this (or a little more skilled than me).
We cut a hole into the drywall ceiling to expose the joists.
Turns out the joists are 12 inches deep with 3.5 inches of insulation sitting on the drywall ceiling leaving 8.5 inches of space between the insulation and the vapor barrier.
The solution? Like Maynard and many others have said... spray foam.
I sat down and did some calculations and although I would save a couple of hundred (possibly $400) to go with pink insulation or blown. I would have to do this myself and it would be a messy project.
I am going to have my brother in-law back his truck into the garage and from there we can rip the existing ceiling down right into the truck and haul it away.
After that have the spray foam guys come in and spray it all up.
Unfortunately I don't want to do this during the cold months so it looks like I ride this winter out and do it next year because my budget for the house is all but tapped out (Geothermal heating, insulation in the roof, new windows and doors for entire house). |

| I also received the same advise to buy liquid nails and glue styrofoam insulation to the existing ceiling. I am glad that prior to doing so I checked on line to see if this would correct the problem. I appreciate your response. Sure wish it was as easy as adding to instead of ripping down ceiling.
Thanks again and good luck to you. |

| It might still be an option for you if the insulation in your ceiling is more substantial than mine. The problem with mine is the eight and a half inches of air between the insulation and the floor.
I was all prepared to do the no nails and styrofoam but the big gap pf air would of been a problem and it would of been a waste of money.
I would do what I did and cut a hole in the ceiling to see what you have up there in terms of insulation before deciding not to go the styrofoam route. |
