Room above garage cold


I have room over attached garage which gets very cold than rest of the rooms. I think there is no insulation in the garage ceiling (I havenít check it yet). I saw some suggestion online and some of them mention taking the sheet rock off and using spray foam. I do not want to go that route since it will be costly option.

What I am thinking of doing is have someone use blown in insulation in the garage ceiling or take down the sheet rock put the foam board between hoist seal it with spray foam can. And then put batt style insulation and put the sheet rock and finish it. Is this a still good options?

Sure seems like these options would be easier from the top, especially the blown-in idea. I think step 1 is figure out whether you have anything in the space and, if so, what. Keep in mind that air sealing between the garage and living space is important as well.

If you haven't checked, I bet it is insulated and that you just don't have enough heat out there to keep up with the heat loss. Rooms that are surrounded by exterior walls on 3 sides plus being cold on top and bottom means they will be cold.

Yes I would not assume that the floor is the problem.

Usually if a room is cold due to insulation problems then it is the ceiling that is the culprit.

Get an infrared thermometer (gun) (they are fairly cheap) and check the floor/walls/ceiling.

Also as XSleeper said it could be that the heating for this room is inadequate.
If you thing it is this and it is forced air then partially close the floor vents on this run so more air goes to this room.
