This is why I routinely install foil/bubble/foil less than an in-flooring radiant heating procedure 4" from the subfloor. This is without doubt one of the two simplest and price-powerful locations to employ a radiant barrier. The opposite Attic insulation is under the roof in almost any climate, Unless of course the roof covering is white.
