Description

Vapour/Air Barrier Low Density Polyethylene For 4-11/16" boxes (25-Pack).

Specifically engineered to create a high-performance seal around Hubbell boxes, this barrier effectively blocks the uncontrolled flow of moisture-laden air into wall cavities. By preventing air leakage, it eliminates cold drafts and protects your insulation’s R-value, significantly reducing energy costs while preventing the long-term structural rot and mold growth caused by interstitial condensation.
Manufactured from durable, high-density polyethylene, this barrier remains flexible enough to wrap securely around the electrical box even in cold-weather installations. This material resilience ensures a tight, custom-molded fit that won't crack or tear during the rough-in phase, providing a permanent seal that adapts to standard wood or steel stud framing without the need for messy spray foams.
Designed to satisfy stringent "tight building" requirements, this accessory allows contractors and DIYers to maintain a continuous air barrier across electrical penetrations. Using this dedicated vapor boot ensures your project easily passes Blower Door tests and meets local energy-efficiency standards (such as Section 9.25 of the NBC), ensuring your home or commercial build is fully certified for occupancy.
