Insulation help for my garage with pics

Garage Journal is a great site! You can insulate the top part of your rafters just below the roof (at an angle). You just have to leave a space for air to pass through.
In Australia they insulate the ceiling and the roof to stop heat from getting into the house. Will work the same to keep it in. Just make sure you leave an air space. The same idea as putting in your insulation stops by the soffits.

As for tape on the garage door, you can use the red tuck tape, sticks like **** to a blanket. But I would recommend silver foil tape. Works the same as tuck tape but is more esthetically pleasing to the eye.

I am a sheet metal mechanic and we use it all the time. I have even seen it used on a 68 barracuda to simulate the top piece of the trunk trim. You would be surprised with a little thin black pinstripe how good it looks from 5 feet away!

Good luck with the garage.
