Abstract: A wall baffle system preferably includes a plurality of girt insulation blocks and a plurality of reflective insulation panels. Each girt insulation block preferably includes a contoured bottom surface, a girt cavity and a retention projection. Each reflective insulation panel includes a foil heat reflective strip and an insulation block. The foil heat reflective strip is affixed to a top or bottom of each insulation block. The girt insulation block is installed under each horizontal girt along a height of the outer wall. The plurality of reflective insulation panels are placed between a floor girt and a bottom of a girt insulation block; between a top of a horizontal girt and a bottom of a girt insulation block; or a top of a horizontal girt and a bottom of an eave girt insulation block.
