How much energy efficiency can window treatments add to a home?

Most windows have an R-value of 0.9 to 3.0 and can be responsible for 40 to 70% of heat or cold transfer for an entire home. Using layers and cellular construction treatments at your windows can increase R-value by 1 to nearly 5 points. In extreme climates, that could save more dollars than you would spend to install windows with a higher energy efficiency.
