Shutters and R-Values: Compare Energy-Efficient Window Treatments06/13/2017Danielle Micich We make a big deal about energy efficiency in window treatments. But that’s because we have proof to back up our claims. With the help of some outside research, we’ve been able to directly compare the energy efficiency of the most often-chosen window coverings in Fort Lauderdale, from blinds to drapes to shutters. What’s An R-Value And Why What Does It Mean For Window Treatments? Everything in your home that insulates, from the roof to your windows, has an R-value. That value tells you how effective it is at preventing thermal energy from going through it. A higher r-value means a better insulator. So what difference can the r-value of a window covering make? Simply put, a more effective insulator makes it easier to keep your house at the temperature you want. Whether you want to keep in the heat during the winter or want to stay cool in summer, great insulation is a requirement. That’s especially necessary 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 when it comes to insulation. Though there’s some variation based on the material and build between different companies and makes, here’s what you’re likely to find when comparing window coverings. Window Covering Average R-Value No window treatment 0.75-1 Blinds 1.5-2 Shades 2.5 Drapes 2-3 Hardwood Shutters 3-4 Cellular shades 4.5 Polywood plantation shutters >6 R-value averages sourced from HouseLogic & Energy.gov. A short glance at the chart shows you a couple of things. Perhaps the first thing you notice is the fact that a few certain window treatments offer almost no benefit whatsoever (we’re talking about you, blinds), while others are total workhorses in insulating. That big gap in R-value could mean a difference of several degrees – enough to make an impact in whether or not you crank up the AC. You might also notice the fact that what the window treatment is made out of makes a big difference. Cellular shades, designed with multiple insulating layers designed to repel heat, are able to put a stop to temperature flow much more effectively than pleated shades. The same way, Polywood® plantation shutters, built from a solid-body faux wood compound, are able to block heat a to a much greater degree than hardwood shutters. That’s because natural wood can be cavernous, with random gaps and knots that allow heat to flow through them easily. Polywood shutters, combined with seamless weatherstripping, build a solid seal on your window when shut, which is the reason for their top of the line r-value of 6 or more. Up Your Home’s R-value The data doesn’t lie. Your window treatments play a big role in how comfortable your house is. Ever feel like your house could stand to be a bit more comfortable? We’ll help.
