When a house is tightly sealed this will, not only help lower the amount you spend on your monthly utility bills, but it can also help improve the home's indoor air quality and comfort, this is also something that most homeowners can do themselves.
A good place to start when it comes to sealing and insulation is the homes attic space, this is because hot air rises so air leaks are more likely to felt at the highest point. Begin by plugging up the larger holes, these are more commonly found in dropped ceiling areas, behind or under attic knee walls, and where the attic wall meets the floor. Smaller holes can be sealed. These small holes can often be detected by the presence of darkened areas in the attic’s insulation. The attic’s access panel is another area that will benefit from weather stripping or foam board insulation.
When you have taken care of the attic space what other places might need insulating or sealing? Some other areas of the home may include window or wall mounted air conditioning units, window frames, baseboards, electrical outlets or receptacles, doors, and areas around piping.
Yes, many areas of the home will benefit from being properly sealed and insulated. By doing this you will increase the home's energy efficiency and save on heating and cooling costs.
