I have a 2 bedroom townhouse & the master bedroom is located on top of the garage. Also I have a 6 foot wide patio door on one side of the bedroom. Because of the above two reasons ( I think), the temperature in this room is around 6-7 degrees below the temperature in the living room where the thermostat is located ( single zone control)

I like the bedroom door closed when I go to sleep, As a result of this the temperature in the room still falls furthur( 8-9 degrees)

Is there some kind of insulation that I can install to the ceiling of the garage ( like an add on ) that will provide better insulation to the bedroom ?

Also If I Cut 1/2 inch off the lower portion of the bedroom door, will air circulation improve the situation

OK,..First of all Insulation is important, but do you have returns in the room? This master bed is probably furthest from the furnace right?
On thing you can do is to adjust the dampers at the furnace trunk line to slow the airflow to the living room and other lower areas of the house. This will cause the furnace to run longer and equalize the wide temp diff. Your are right, that insulation should be added, but what you have is a ballance problem in air flow. Remember that the furthest run will not only be cooler, but have a-little less air flow.

Hope this helped.

A couple of small things you can do:
Put insulated drapes in front of the 6' patio door.
Make sure the attic space above the bedroom is insulated well.
If the master bedroom has a private bath, make sure there's no draft coming through the exhaust fan vent.

How can I confirm if the insulation in the attic is enough ?

TO determine if you have "enough" insulation, look at it, measure it, and research the R-value for your home and the R-value that the depth of insulation you measured provides. You can add additional insulation, even if it meets the recommended R-value for your area. The R-values values differ throughout the country (depending on how far North you are). They also differ from insulation to insulation, so no specific answer can suffice.

As for your original question, there are plenty of insulation options for the ceiling of the garage, especially because losing an inch or two of space down from the ceiling should not be an issue in a garage except for a few isolated spaces. It also is a good presumption that your problem lies there.

What you use somewhat depends on what is already on the ceiling: is it finished with drywall or do you have exposed beams? If exposed beams, obviously put regular fibergalss insualtion between the joists and drywall it. There are also plenty of different rigid insulation boards you can apply to the ceiling no matter what is on it already. But the best thing would be to determine what sort of insulation, if any, the ceiling currently has, and then add to it if it is insuffucient.

Also, the problem might be the result of a poorly-engineered duct system. Your bedroom is probably at the end of your duct run, and simply might not be receiving enough heat. So in addition to the other good quick-fixes other people recommended (insulated curtains being perhaps the best), you can of course adjust the vents by closing the vents outside the bedroom and purchasing a vent that does not restrict air so much in the bedroom so as to force more heated air to the bedroom. Doing so does make your furnace work harder, though, so more/better insulation is the better long-term solution.
