Description
The Hubbell HVB1BAR is a universal single‑gang vapor barrier designed to enclose a standard 2" × 3" electrical device box and maintain the integrity of a wall’s air and moisture seal. Made from durable polymer/polyethylene, it forms a protective envelope around the box to prevent exterior air from penetrating the building envelope and to help preserve interior environmental conditions. Its molded rear bumps allow clean, right‑sized cable cutouts, while the flat perimeter outline ensures a tight, continuous seal against surrounding vapor‑barrier materials. This makes it a practical accessory for energy‑efficient construction, improving air‑sealing performance in both residential and commercial installations.
