How to Insulate Light Switch Wall Plates

Light switches are not normally what comes to mind when looking for ways to insulate your home. However, heat can be lost through light switches and electrical outlets. These are normally connected to an electrical service via channels that lack fiberglass or similar insulating materials. Prevent heat loss through light switches by insulating the wall plates covering the electrical boxes.
