Energy efficiency is a relative newcomer to the window treatment repertoire, although in truth, many types of window coverings have played a role in indoor temperature control for centuries. In the late 20th century, however, industry innovators began focusing on the energy-efficient aspects of window treatments as the nation reacted to skyrocketing fuel prices and concerns over the depletion of natural resources. As a result, today’s homeowners have a generous array of energy-efficient window coverings to choose from.

The U.S. Department of Energy’s Take on Window Treatments

The government’s top energy experts recognize the important role that window coverings play in helping homeowners reduce their energy consumption related to indoor climate control. The best energy-efficient window treatments listed by the Department of Energy include:

Cellular Shades

Also known as honeycomb shades, these pleated window coverings are designed to trap air and use it as insulation. They have the highest R-values of all window treatments.


Both horizontal and vertical blinds are highly effective at blocking heat gain through the windows during the summer. They are less effective at preventing loss of indoor heat during the winter, according to energy experts.


The energy efficiency of curtains and drapes depends on a number of factors, including the tightness of the fabric weave and the color. Studies show that medium-colored drapes with white plastic backings can reduce heat transfer by up to 33%.
