So preparing my garage for insulation, all the walls are done and have vapor barrier.i put the insulation stops in between the trusses and vapor barrier and drywalled my ceiling.So know my problem, im sure i put them in wrong.(insulation stops)well they would do the job but i dont think they are the strongest way to be installed.what is the correct way to install these damn things, i heard they are supposed to be installed before the roof panels go on the roof.thanks
