Protect Your Installation with the Ortech Vapour Barrier When installing recessed LED lighting or ceiling fans in insulated spaces, maintaining a proper air and vapour seal is essential — not just for energy efficiency, but for building code compliance and long-term performance. The Ortech VB-6-S Vapour Barrier is specifically designed to create an airtight seal around LED pot lights and ceiling fan installations, preventing warm moist air from penetrating your insulation and ceiling cavity. Why Use a Vapour Barrier? Without a proper vapour barrier, moisture-laden air can infiltrate your ceiling, leading to condensation, mould growth, insulation damage, and reduced energy efficiency. In Canadian climates — where temperature differentials between interior and exterior are extreme — this protection is not optional. The VB-6-S by Ortech provides a reliable, easy-to-install solution trusted by contractors and homeowners across Canada. Simple Installation, Professional Results The VB-6-S is straightforward to install and compatible with standard LED pot light and fan openings. Whether you're completing a new build or retrofitting an existing ceiling, this vapour barrier integrates seamlessly into your workflow. It is the ideal companion for any recessed LED or fan installation in conditioned living spaces with insulated ceilings.
