I. have a sun room built on a elevated concrete slab with a ceramic tile floor, forced air heating insulated to R-13 wall, R-19 celing,GI windows. The floor is extreamly cold, would glueing 2″,R-10 blue board cell foam to the underside and down the fan wall provide any relief to this problem? The crawl space under the room is open to the house crawl space, additionally the air ducts are in under the slab. Height of crawl is bat 28″. Spray urthane foam is not an option, based on $ due to lack of contractors in the area. Any suggestions will be appreciated.
