R-Values of Shutters: Compare Energy-Efficient Window Coverings

We’re big talkers on the subject of energy-efficient window treatments. That’s because we’ve got proof for our claims. With the help of some outside research, we can directly compare the energy efficiency of the most common window coverings in Raleigh, from drapes to blinds to shutters.

What’s An R-Value And Why Does It Matter For Window Coverings?

Everything in your home that separates the inside from the outside, from the walls to your window treatments, has an R-value. That value tells you how good it is at preventing thermal energy from passing through it. A higher r-value means a better insulator.

So what difference does the r-value of a window treatment make? Basically, a more energy efficient window treatment makes it easier to keep your home at your preferred temperature. Whether you want to keep the heat inside at wintertime or keep the heat out during the summer months, great insulation is a requirement. That’s especially crucial for your windows, because they’re a likely culprit for energy loss in your home.

Comparing R-values & Energy Efficiency Of Window Treatments

Not all window treatments are made equal, at least not in insulation. Though there can be some variation based on the material and build between different manufacturers and models, below is what you’re likely to find when comparing window coverings.

R-value averages sourced from Energy.gov and HouseLogic.

A short study of the chart shows you a number of things. Perhaps the first thing you notice is the fact that a few certain window treatments barely give you any benefit whatsoever (looking at you, blinds), whereas others are total workhorses in insulating. That difference in R-value could mean a difference of several degrees – that’s the difference in whether or not you crank up your AC.

You might also notice the fact that the material of your window treatment can have a big impact. Cellular shades, which are made with multiple engineered layers designed to trap heat, are able to put a stop to temperature flow much better than pleated shades.

Similarly, Polywood® plantation shutters, built from a solid-body faux wood polymer, are able to block heat a to a much greater degree than natural wood shutters. That’s because natural wood can be porous, with natural gaps and holes that allow heat to flow through them easily. Polywood shutters, fit with strict weatherstripping, make a solid seal on your window when closed, giving them that best in class r-value of 6 or more.
