- For optimum insulation performance the building thermal barrier (insulation) should be in continual alignment with the building air barrier.
- 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.
