June 23, 2022

Energy conservation should be a huge requirement for your window treatments in Boston. With the wrong treatment, you might feel a good deal of heat loss, which may lead to larger heating and cooling bills. To discover the best energy-efficient window treatments, you will have to look at their R-values.

But what window treatments own the highest R-value in Boston?

Everything in your home that plays a part with insulation -- from drywall to your windows -- gets an R-value. That number represents how well the item hinders thermal energy from traveling through it. A larger R-value indicates a more efficient insulator.

But why should you worry about a window treatment’s R-value in Boston? Well, because windows are one of the most common energy wasters in your house. If you have to keep in the hot air during wintertime or keep your rooms cool in the warm times, you need a window covering with more insulation. A window covering with a big R-value lets you keep your rooms at an optimal setting.

Every window treatment is not created with the same care, which is a large part in how they insulate. Though there can be a little variation with the materials and quality between different makes and models, here’s what you’re probably to find when contrasting window coverings.

Bare window 0.75 - 1
Mini-blinds 1.5 - 2

Keep in mind, the higher the R-value the more efficient the window treatment. It shouldn’t be a shock that mini-blinds, which are made with thin aluminum, bring almost no insulation when compared to a more substantial product, like faux-wood shutters. That big gap in R-value can be seen in a difference of several degrees – enough to feel an impact on if you dial up the thermostat and make your energy bills rise.

Two things affect a window treatment’s R-value: construction and materials. To start with, coverings that have an ample amount of avenues for heat to escape won’t get a large R-value. For instance, curtains and blinds just hang there, letting air to leak out around the sides and bottom of the treatment. However, interior shutters are custom-crafted snuggly around the window opening, keeping air against the window’s glass when the louvers are completely shut.

Then what materials the product is made out of can have a significant impact to insulation. Take cellular shades, which use several ​​engineered layers of fabric that create “cells” to trap heat. As a result, they will block temperature flow more efficiently than treatments like pleated shades. Likewise, our Polywood plantation shutters, built from a impenetrable faux wood material, can block heat loss more than hard wood shutters. Polywood shutters also use seamless weatherstripping, which results in a air-tight seal when the louvers are snapped shut.
