Energy Efficient Window Coverings: Features of Good Blinds for Windows
Windows are the single largest means of heat loss in the average home. Not only do windows allow the heat inside a home to escape, but they can also allow heat into a home during the hot summer months. Energy efficient window coverings insulate your home against heat loss, with each type of covering offering a different level of protection. Here’s how you can choose the best energy efficient window coverings for your home:
Two Things to Look For in Energy Efficient Window Coverings Before Spending Your Hard-Earned Dollars
- Consider R-values When Making Your Decision
The higher the R-value of a window covering, the more it will protect your home from heat loss. Standard blinds have an R-value of 1. Honeycomb shades offer a value of between 2 and 4.8, while window quilts with air and moisture-tight fabric and four sided seals rank at 4.99. Depending on the fabric, lining and pleating, the value of roman shades is 3-5, the same as draperies.
- Consider the “Shading Coefficient” of the Different Options
The shading coefficient is the measure of the window’s ability to reduce the solar heat gain. The lower the number, the less solar heat will enter your home and the lower your cooling bills will be. Untreated windows will allow about 20 times more heat into your home than an equal amount of window space covered with energy efficient treatments. You can save on summer energy bills and take advantage of free heating in the winter by controlling the way the sun’s heat enters your home.
Consider window treatments before spending money on double glazed windows and other window glass replacement options. You can add to your energy efficient window coverings by sealing drapery edges to the sides of windows with magnetic tape or Velcro, which will cut down on heat loss from your home.
