• For optimum insulation performance the building thermal barrier (insulation) should be in continual alignment with the building air barrier. In framed cavities, the product thickness should match the depth of the framing members.
  • Follow the local, applicable building code(s) to determine the need for and placement of a vapor retarder.
  • Do not install insulation on top, or within 3 inches of a recessed light fixture unless the fixture is labeled as “insulation contact” (IC) rated.
  • Kraft and standard foil facings will burn and cannot be left exposed. Install facings in substantial contact with the assembly finish material.
