The attic spaces. Due to the fact that heat rises the attic is an area that you will notice leaking air. You will often experience bigger gaps and holes in dropped ceiling areas, behind or under attic knee walls, or the area where the attic meets with the floor, so you will want to plug up any of the holes you find there. Next, seal up small holes. If you are wondering how to find smaller holes, one clue to watch out for is patches of insulation which have become darker than the rest. The attics access panel is another area that will benefit from weatherstripping or foam board insulation.
As well as the attic, what other areas of the home can benefit from sealing and insulating? Some places you will want to check are doors, window frames, baseboards, window or wall mounted air conditioners, electrical outlets or receptacles, and piping.
These are just a few of the places throughout the home that can become more energy efficient if they are sealed or insulated. Plus, as well as saving you money on cooling and heating costs, a tightly sealed home will also contribute to better indoor air quality and comfort.
