• Measure and cut a 2" sheet of R-max to fit between the double ceiling joists.
• Measure, cut, and place a 2" piece of R-max above the light support that is at least 8" longer
than the gap and center this piece over the gap.
• From the outside of the cooler drive two #12 x 4" long plastic cap nails through this small piece
of R-max and into the light support 2 by 4.
• Do not drive the nails all of the way - allow for the R-max to rise 1/2" above the 2 x 4 as shown
by the finger gap in the photo.
• Use spray foam insulation to fill the 1/2" gap cementing this piece to the main ceiling insulation.
PRO TIP
Before putting the second layer of insulation on the ceiling, remember to mark on the side walls the
location of your joists (to hang the rack system) as well as the 2 by 4 in between the joists that will
hold your Light fixture.
