Spray-on radiant barrier coatings are slightly less effective than foil, but they can cover more area or hard-to-reach pitches. The two types generally differ in emissivity or how much radiant energy passes through (less than 10%); however, radiant barrier foil reflects more incoming heat than spray coating.
Is radiant barrier expensive?
On average, professional radiant barrier installation costs range from $300 to $2,000 depending on several cost factors. Single-sided radiant barrier costs range from $300 to $500, while double-sided radiant barrier costs anywhere from $600 to $1,200 according to Barrier Insulation.

Which is better radiant barrier or spray foam?
Open-celled spray-in foam insulation is by far superior to a traditional radiant barrier which is a foil-like thing that you can either tack to the rafters or lay on the floor of your attic. Open-cell foam is also more expensive, but in my opinion an excellent investment.
