• Effect of Radiant Barriers in Wall Construction

      Estes, Mark; Olson, Todd (1988-01)
      The performance of radiant cardboard barriers were tested and evaluated using the DOT&PF guarder hot box. Two types of insulation were used in the testing fiberglass bat and blown cellulose. The test procedure consisted of obtaining temperature measurements at designated positions throughout seven types of wall configurations. These tests showed, that the configuration with 5.5 inches of fiberglass bat insulation compressed to 4 inches with a radiant cardboard barrier allowed the least total heat flux through the wall section. An economic analysis indicated that the use of radiant barriers may be feasible in situations where insulation support is needed or an uninsulated gab is required for wiring or utilities.
