An insulation block is utilized with a corresponding baffle vent having a transverse width that will span several roof rafters, as is provided for use with manufactured housing. The insulation block includes uniformly spaced vertical ribs that extend from one edge of the insulation block to the opposing edge thereof to stiffen the insulation block which is formed of vacuum molded polyvinyl chloride film. After the baffle panel is placed on top of the roof rafters, which is before the roof sheeting is applied, the insulation block is attached to the wall top plate with the top edge of the insulation block placed into engagement with the baffle vent. The top edge of the insulation block is configured to mate with the undulating configuration of the corresponding baffle vent, fitting between transversely extending stiffening ribs on the baffle vent, to prevent insulation from entering the soffit area.
