Eurofase Lighting ALRIN-00 Housing, 3 1/4In Insulated Ceiling, Alre

Must be used in any ceiling where there is insulation. This housing incorporates a box which creates an air space between the inner fixture and the insulation. Unless there is access from above via the attic, the size of the box makes insulated housings suitable only for new construction applications.
