Shutters and R-Values: Compare Energy-Efficient Window Treatments06/13/2017Greg Arnett We make a big deal about energy-efficient window treatments. But that’s because we’ve got the numbers to back up our claims. With the help of some outside research, we’ve been able to map out the energy efficiency of the most often-chosen window treatments in Phoenix, from shades to blinds to shutters.What Is 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 coverings, has an R-value. That number tells you how effective it is at blocking thermal energy from moving through it. A higher r-value means a more effective insulator. So what difference can the r-value of a window covering make? Basically, a better insulator lets you keep your home at the temperature you want. No matter if you want to keep the heat inside at wintertime or want to stay cool during the summer months, great insulation is a requirement. That’s extra necessary for your windows, because they’re a big reason for energy loss in your home.Comparing R-values & Energy Efficiency Of Window TreatmentsEvery window treatment is not made equal, at least not in terms of energy efficiency. Though there can be some variation based on the material and construction between different companies and makes, below is what you can expect to find when comparing window coverings.Type of Window CoveringTypical R-ValueNo window treatment0.75-1Blinds1.5-2Pleated shades2.5Drapes2-3Wood Shutters3-4Honeycomb shades4.5Polywood plantation shutters>6R-values from HouseLogic & Energy.gov.A short look at the table tells you a couple of things. The first is the fact that a few certain window treatments offer almost no benefit whatsoever (ahem, blinds), whereas others are insulating powerhouses. That big gap in R-value could mean a difference of several degrees – that’s the difference in whether or not you turn on your AC.Something else you might notice is that the material of your window treatment can have a big impact. Honeycomb shades, designed with a number of engineered layers designed to trap heat, are able to put a stop to energy flow much better than pleated shades. The same way, Polywood® plantation shutters, made from a solid-body faux wood polymer, can keep out heat a to a much greater degree than natural wood shutters. That’s because natural wood can be permeable, with natural knots and holes that allow heat to flow through them easily. Polywood shutters, outfitted with seamless weatherstripping, make a solid seal on your window when closed, which is the reason for their best in class r-value of more than 6.Add More Value To Your HomeThe science doesn’t lie.
