Hay guy's I need your help! I just had this garage put up and want to put so insulation in it. It's 20x30 and 11 foot walls. The studs are 5 foot apart and 2 1/4 thick. What should I use?
That would be probably the best but it's not going to be cheap. Maybe some 2" pink rigid insulation. You'll have to run the sheets sideways and cut to size to wedge them into the space between the metal studs.
This is one reason I don't like those pre-fab type of garages, while they might be cheap in the beginning, they're not as easy to finish off in the inside.
