1. Are spray on radiant barriers effective inside the attic (sprayed on attic ceiling)? Are there any websites that I can review tests that have been performed on theses materials? I would prefer one that doesn't contain harsh chemicals / VOC's) Also, can I use this material on knee walls (I would place the insulation OVER the spray-on radiant barrier to prevent moisture penetrating the fiberglass batts. I guess what I'm thinking of is using the spray on barrier material as both a vapor barrier and a radiant barrier.

2. I want to seal the spaces in my attic where the drywall crown meets the attic as well as some knee wall areas. Is there a spray that I can use with an airless sprayer that will seal small (1/8 inch) crevices? Refering to #1 above is there a radiant barrier spray that will do both jobs.
