How Energy Efficient is Your Home?
Heat flows naturally from warm places to cooler ones. Without insulation, heat can flow freely in and out of your home, letting warmth escape in winter and enter in summer. Insulation decreases heat flow, helping maintain a more uniform and comfortable temperature throughout your home year-round. You can generally get the most savings by ensuring that your attic is properly insulated. This includes insulating your attic hatch and sealing it with weatherstripping. To find the proper insulation R-Values for specific areas in the home, visit the Georgia Department of Energy web site.
Heat doesn't just flow through the attic. Crawl spaces or unfinished basements that lack proper insulation can also decrease efficiency in your home, allowing heat to flow through floors. It is important to control moisture in crawl spaces by ensuring that there is proper drainage and that insulation has a moisture resistant backing.
Answer the following question if you have walls adjacent to unconditioned attic space.
Is your bonus room always too hot in the summer and too cold in the winter? Did you have to buy an additional heating and/or air unit to make it more comfortable? This could be because your walls adjacent to unconditioned attic space are not properly insulated. Be sure that you have the recommended level of insulation between studs and insulation board covering the studs on the attic side of the wall.
