Add insulation to your walls
Why This is Green
When properly installed, insulation reduces the energy necessary to heat your home in the winter and cool it in the summer. Reduced energy means lower bills, results in fewer emissions, and consumes fewer natural resources. A perfect trifecta.
Almost any insulation can be considered green because of the energy benefits, but some materials are eco-friendlier than others. Some manufacturers use high percentages of recycled content, or substitute natural castor oil for petroleum-based materials. There are versions created from recycled blue jeans, recycled newspaper newspapers, and wool. Some foams are made from renewable products like soy, and avoid use of ozone-depleting chemicals. Steer clear of dangerous ingredients such as formaldehyde, a “known” carcinogen in Europe and a “suspected” one in the U.S., which has also been linked to allergies and asthma and is routinely used as a binder in insulation.

How To
Have an experienced contractor conduct an analysis of your home’s walls, and then walk you through your options.
Air sealing any leaks before adding new insulation is common practice (and highly recommended!). Wall insulation is often installed in combination with added roof insulation.
Tip: ask your contractor if insulation close to R-40 can be added to your walls (the R factor is the measure of resistance to heat flow). This will assure maximum effectiveness, quicker payback from your investment, and provide extra comfort throughout the home. Bonus!
