Bare window 0.75 - 1
Aluminum blinds 1.5 - 2
Window shades 2.5
Draperies 2 - 3

Remember, the larger the R-value number the more energy-efficient the window covering. No surprise that cheap blinds, usually made of thin aluminum, bring almost no protection when compared to a more solid covering, like durable faux-wood shutters. That insurmountable gap in R-value can result in a difference of several degrees – enough to feel an influence on whether you dial up the thermostat and increase your energy use.

A few things affect a window treatment’s R-value: construction and substance. To start with, treatments that have an ample amount of ways for heat loss won’t own a large R-value. For instance, curtains and blinds don’t firmly cover the window, allowing heat to leak out around the sides and bottom of the covering itself. On the other hand, interior shutters are custom-made snuggly around the window, keeping heat against the window when the louvers are completely shut.

Then what the product is made out of can also bring a big impact to insulation. Take cell shades, which use several ​​engineered layers of fabric designed to trap hot air. As a result, they can block air disbursement more effectively than coverings like pleated shades. Likewise, Polywood interior shutters, built from a impenetrable faux wood material, can trap heat loss more than hard wood shutters. Polywood shutters also has seamless weatherstripping, which creates a tight seal sound your windows when the louvers and panels are completely shut.
