Progressive Foam’s Halfback H20 Premium Series insulation uses BASF’s Neopor thermal foam, whose graphite particles boost R-value. A 3.5-perm rating prevents thermal bridging without trapping water vapor, while grooves on the panels’ backing direct moisture down and out the bottom of the wall to improve drying.
