As an example, if a radiant barrier is used earlier mentioned the roofing felt before a tile roof is mounted, radiant heat from the bottom area from the tile is mirrored into your air House among the tile and the roof deck. (While with no radiant barrier, the heat is carried out with the asphalt felt and Wooden roof deck and radiated into your attic air Area raising attic temperatures to as higher as 150 levels.
