An estimated nine out of 10 homeowners are wasting money on their energy bills because their homes, particularly older houses, are under-insulated, according to Energy Star. And one of the major sources of escaping energy is often one of the most overlooked: the attic.
Identifying the depth of the insulation in your attic is the first step to addressing your energy usage. Homes in the Chattanooga region should have about 14-16 inches of attic insulation in order to efficiently maintain a desired level of air quality.
In addition to the depth of your insulation, you or a professional contractor should also inspect some attic features that notoriously allow air to seep in or out.
· Electrical boxes – Temporarily clear away any of the attic insulation surrounding the electrical box and apply the insulation foam per the manufacturer’s instructions around the box’s perimeter. Let the foam cure and dry for at least 30 minutes before replacing the surrounding attic insulation.
· Plumbing pipes – Temporarily clear away the attic insulation from the base of the pipe. If you notice a sizeable gap between the floor and the pipe, insert a small piece of fiberglass insulation into the gap before applying the insulation foam around the base of the pipe. Let the foam cure and dry for at least 30 minutes before replacing the surrounding attic insulation.
· Recessed lights – An insulator cap should be used to enclose the light’s housing. You might need to make small cuts to the rim of the insulator cap so that it lays flat and allows room for the protruding metal supports. Apply sufficient insulator foam around the perimeter of the cap and let it cure and dry for at least 30 minutes before replacing the surrounding attic insulation.
Pinpointing and addressing these potentially problematic areas, as well as the overall insulation depth in your attic can make a noticeable impact on your home’s energy efficiency and environmental impact. Investing in these solutions will not only begin to make your home feel more comfortable, but you can also begin to see a return on that investment within your utility bills.
As you tackle these projects, be sure to take all safety precautions, including the use of protective eyewear, gloves and appropriate clothing.
