Roof insulation panels are set in a continuous serpentine pattern of three-quarter to one-inch foam adhesive beads spaced four inches on center. The adhesive pattern is offset two inches from the panel edges on all sides across four-foot by four-foot insulation panels. Adjacent panels maintain staggered joints to prevent thermal bridging and air infiltration. This adhesive application is specific to roof corner zones subjected to higher wind uplift pressures.
