Reflective insulation systems are made from aluminum foils with a variety of backings such as roof sheathing, kraft paper, plastic film, cardboard, bubble wrap, etc. The resistance to heat flow depends on the direction of heat flow with this type of insulation most effective in reducing downward heat flow and requiring an air space next to the reflective side. Reflective systems are usually located between roof rafters, floor joists, or wall studs. Reflective insulation placed in walls or on the attic floor must be perforated to allow water vapor to pass through it.
