The Liteline VBE-1 is a PVC vapor barrier extender designed for use with Liteline IC-rated recessed fixtures — an essential rough-in accessory for electricians and contractors working on energy code-compliant installations in insulated ceilings and walls. In Canadian climate zones where airtightness is a building code requirement, maintaining the integrity of the vapor barrier around recessed lighting penetrations is critical. The VBE-1 creates a proper seal between the fixture and the vapor barrier membrane, preventing conditioned air from escaping into attic spaces or wall cavities and stopping cold air infiltration in the opposite direction. This directly supports compliance with the National Building Code airtightness requirements and helps avoid callbacks related to drafts, condensation, or energy performance issues. Suitable for ceilings, walls, and damp locations, it’s a low-cost accessory that protects both the building envelope and the contractor’s reputation on every IC-rated install.
