Window shades usually are not the first thing that comes to mind when you think of green behavior. There are a couple of areas where shades can directly impact the green rating of your house, they two areas are off-gassing and energy efficiency. The biggest impact from shades can be their energy savings. There are a couple of ways the shades help, keeping the heat out or keeping the heat in your house. Light colored fabrics will reflect the sun’s rays which reduces solar gain and help keep the indoor temperature lower. In addition to reflecting heat insulating shades can also keep the heat (or cool) in the house. Insulating shades have R ratings of up to 5.0 or higher, these factors along can save a considerable amount on your energy bills.
In addition the the energy savings there are indoor air quality issues with some shades. The majority of shades have a thin coating of PVC to increase the durability of the shade. Now more manufactures are also creating PVC-free shades that use other, more environmentally friendly, coatings to provide the durability. You still need to be careful since the replacement coatings are not always harmless, be sure to check with the manufacture for details.
