Some types of regular window coverings and blinds provide a basic level of insulation. Wood blinds and synthetic wicker window treatments are fairly heavy and reduce the effect of the elements from outside the window, particularly bright sunlight. These are among the most inexpensive options for window coverings.

On the Other: Insulated Window Coverings

Window coverings that are designed for the purpose of providing insulation can vastly improve home comfort. These window coverings are custom fitted to eliminate dead air space. Also, they are made of honeycombed or cellular construction to block heat transfer and are designed to protect against UV radiation. They are a more expensive type of window covering, and to get the best results they should be measured and installed by a contractor.

Bottom Line

Custom fitted window coverings that are designed to provide insulation against cold and heat are superior for this purpose, and for windows that are highly exposed to the elements they are the best choice. They are more expensive than ordinary window coverings, but according to The Smart Energy Living Alliance, these types of window coverings can block up to 62 percent of the heat transfer through a window pain. As a result, you have the chance to get your money back on gas and electric bills.
