And, when coupled with Solar Gard window film, Polywood shutters are your prime choice for the highest savings on your energy payments. The Polywood Shutter Insulation System Shutters are the most energy-efficient window treatment. And our Polywood shutters, with their exceptional insulation system, are the best energy saving shutters in Chicago – if not the US. We carefully construct each component of our Polywood Shutters with energy efficiency in mind so you can enjoy the energy savings. The unique solid polymer material Polywood is made from is dense enough to block air flow. This transforms these shutters into a natural insulator. The sides of the shutters have weather-stripping pieces that seal shut to block more light and temperature than any other shutter. This dramatically reduces heat transfer around the panels in both the hot summer and the cold winter in Chicago. Top that off with a heat-reflective paint, and you get a shutter that is not only beautiful but also extremely energy efficient. In fact, Polywood shutters insulate up to 70% better than a comparable wood shutter. A third party thermal test (forward looking infrared) showed that the Polywood Shutter Insulating System blocked as much as 30 degrees of temperature coming through the window. This means the HVAC system doesn’t have to work as intensely. Here’s how Polywood provides you with more energy savings than any other shutter: Stops Air Flow. Polywood’s thermal protection blocks up to 30 degrees of airflow that comes through a window. Maximizes R-Value. Polywood has an R-Value of over 6 in a double-pane window. That’s the highest thermal resistance rating of insulation material of any shutter you can find. Reduces Heat Transfer. Polywood results in a 45.96% reduction in heat transfer. Improves Energy Efficiency. Polywood is up to 70% more energy efficient than wood shutters and up to 1600% more energy efficient than aluminum blinds. Resists Moisture and Humidity. Since Polywood is moisture-proof, it resists humidity and moisture that can impact the temperature of a room. The Polywood Shutter Insulating System combines all of these energy-efficient benefits to save you money on your heating and cooling bills. You won’t find another shutter that looks as elegant, is as durable, or saves you as much on your energy bills as our Polywood shutters. Learn more about Polywood shutters.
