Super R® radiant barrier is perforated, allowing moisture to pass back and forth through the material without the worry of condensation forming in your attic. Condensation buildup can lead to mold and/or mildew formation.
Radiant Barrier Attic Insulation
Super R® radiant barrier is especially effective in an attic application because that is where most of the heat enters or leaves a home or structure. Heat always gravitates to cold, so if you want to keep your home cool in the summer, the heat is trying to get in. If you want to keep warm in the winter, heat wants to seep out of your living space.
