Reflective Insulation can function as a vapor retarder
Two methods to seal the seams.
(1) Tape Tab Tabs from Two Rolls of Insulation Attached Together (2) Staple Tab
IRCCs LO/MIT-I being applied to underside of galvanized roof in chicken house at University of Georgia, Athens, Georgia. LO/MIT-I is an excellent metal building insulation because it lowers interior radiant temperature, in this case, lessening heat loads and death rates during extreme summer heat.
The physics behind the R-Values for reflective insulation systems was reviewed in the opening segment of this program with examples of the modes of heat transfer present in the building envelope and some numerical examples.
Reflective insulations are an integral part of the huge field of building insulation. The basis for evaluating these systems has been well established in recent years.
