The Liteline VBE-2 is a vapor barrier extender specifically designed for use with Liteline 3.5" and 4" retrofit IC-rated recessed fixtures installed in insulated ceilings. For electricians and contractors working on renovation projects in existing homes, this is a critical accessory for maintaining a code-compliant, airtight building envelope around recessed lighting penetrations. Without a proper vapor barrier seal, warm conditioned air escapes into the attic cavity, leading to heat loss, condensation risk, and potential moisture damage — issues that generate costly callbacks and warranty concerns. The VBE-2 eliminates that risk by providing a purpose-built seal between the retrofit fixture and the ceiling vapor barrier, keeping the thermal and air barrier continuous. A straightforward, low-cost addition to any retrofit pot light install in an insulated ceiling that protects both the building and the contractor’s workmanship.
