Whether your home experiences chilly northern winters or sizzling southern summers, energy efficiency will be on your mind at some point during the year.
Shutters are excellent insulators because they enclose the window frame and create a ”sealed” effect. Their construction resists heat transfer better than traditional blinds. Specific R-Values will vary depending on your window’s construction and shutter configuration.
What Does R-Value Mean?
R-Value measures how much a material slows heat movement from one side to the other. The higher the R-Value number the more insulating the material is, and the more you could save on your energy bills. Horizontal blinds will have a typical R-Value between 1 and 2. Shutters typically have an R-value between 3 and 6.
