The Florida Solar Energy Center at Cape Canaveral has tested radiant barriers in both small scale laboratory and full scale building models. Their results indicate that radiant barriers provide significant resistance ...

For radiant barriers to be effective in the north they need to be place on top of mass thermal insulations. This causes three problems: For radiant ...

No. The foil on the fiberglass is in direct contact with the attic floor. Aluminum foil becomes more conductive when in contact with a solid surface. Air space is extremely important ...
