Maintaining an unbroken vapour barrier around recessed lighting penetrations is one of the most critical — and most commonly overlooked — steps in residential construction and renovation. Every opening in your ceiling plane can allow warm, moist interior air to migrate into the attic or joist cavity, where it condenses and can lead to mould growth, wood rot, and degraded insulation performance. The ORTECH Vapour Barrier for 4" LED Slim Lights provides a sealed enclosure specifically engineered to eliminate this risk at each light location.

This accessory is constructed from durable, code-compliant materials that create an effective air-tight seal between your living space and the insulated cavity above. It is designed to work in harmony with modern IC-rated LED slim panels, allowing insulation to be placed directly over and around the enclosure without creating a fire hazard or trapping excessive heat. The result is maintained thermal management performance across your entire ceiling assembly.

The enclosure is cUL approved and meets Canadian electrical and building standards, giving you confidence that your installation will pass inspection. It is compatible with standard 4-inch ultra-thin recessed downlights and supports compliance with increasingly strict energy code requirements found across Canadian provinces, including provisions for air barrier continuity and insulation contact ratings.

Installation is straightforward for both new construction and retrofit applications. The vapour barrier enclosure positions easily above the ceiling plane before drywall is finished, or it can be accessed through the attic space during renovation projects. By pairing this enclosure with your energy-efficient LED slim lights, you ensure that every recessed fixture in your home contributes to lower heating and cooling costs rather than undermining your building envelope's overall performance.
