Air Leak in the Building s Internal Electrical Distribution Box
Stopping air leakage requires a two-pronged approach that seals both the faceplate and the junction box within the wall cavity. Air sealing is a step in improving residential energy efficiency by addressing gaps in the building envelope. Outlets and switch boxes interrupt the continuous barrier of the wall and are common. This article explains how to safely air seal electrical boxes to tighten your home's thermal envelope. Air leaks from these areas can significantly drive up heating and cooling costs, and compromise the integrity of fire-rated assemblies. As such, air-sealing electrical boxes and related. Outlets and switches can leak cold air due to unsealed gaps around electrical boxes, allowing drafts from uninsulated walls, attics, or crawl spaces to enter your home.
