When installing a foil-type radiant barrier, it’s crucial that the material “droops” between the attachment points – allowing for at least a 1 inch (2.5 cm) air space between the material and the bottom of the roof. This involves stapling the reflective material to the bottom of the rafters. In most cases, radiant barriers are installed before the roof sheathing but can it can still be done afterwards from inside of the attic. This helps reduce the accumulation of dust on the reflective surfaces.
