I want to use foil-faced foam board over unfaced insulation on an interior application. The 1/2″ Celutex Tuff-R comes with foil on both sides. One side is more shiny, reflective than the other. The data sheet for the product says one side is reinforced. Does it make any difference which way this is applied? Should the label side (less reflective) be facing the inside of the room? Any comments are appreciated.
