I want to put a radiant barrier in my home’s attic. I plan to staple it to the underside of the attic rafters. Is that a good way to proceed? Also, I have seen materials with bubble insulation between foil faces and I have seen radiant material that is perforated with small holes, apparently for ventilation. Do either of these materials provide a specific additional benefit or is a solid foil material best or equally good?
For your application the solid radiant barrier is best.
