Attach the Hat Channels to the Wall
First, draw a plumb line to make sure the hat channels will be spaced properly for the size of drywall and insulation you're using. The hat channel (Image 1) should be attached to the wall using concrete nails and concrete-nail gun (Images 2 and 3). Drive three concrete nails, spaced at even intervals, through each side of each hat channel.
