Over time, insulation can lose some of its R-value, making it less effective in reducing heat transfer. This can be due to insulation that has settled, become compacted, or has become damp. For San Francisco homeowners, insulation replacement and upgrades can be worthwhile projects that pay off in terms of greater indoor comfort and lower energy bills.
According to the Air Barrier Association of America, the average mid-sized home in the U.S. has a half mile worth of gaps and cracks. Even though many of these are not visible, in aggregate it would be like a home owner leaving several windows open year long. All of this air transfer makes it harder – and more expensive – to heat a house in the winter and cool it in the summer. Even in more moderate climates like San Francisco, all these cracks and gaps can increase monthly heating and cooling bills by 20 percent.
Insulation replacement can help with the energy bills, and it can improve indoor air quality and reduce moisture. As air moves through a home’s walls, ceilings and floors, it carries moisture along with it. Moisture increases the potential for mold and other problems that can lead to allergies and other respiratory problems. Other San Francisco homeowners may be interested in insulation replacement in order to make their homes more green, in addition to energy efficient. San Francisco-area insulation specialists like Atticare can help homeowners assess different environmentally friendly insulations such as cotton and cellulose.
Before undertaking an insulation replacement or upgrade, it’s a good idea for homeowners to contact a professional to perform an energy assessment. This will help them determine how to maximize the value of the project so it provides the greatest benefit over the long term. It’s also a good idea to use a professional when installing insulation. Insulation needs to be installed correctly in order to maximize the R-value. If it’s installed improperly, homeowners will not get the maximum energy-saving benefits.
