The Polywood Shutter Insulation System The most energy-efficient window treatment is shutters. And our Polywood shutters, with their progressive insulation system, are the best energy saving shutters in Kingsport – if not the US. We carefully make every part of our Polywood Shutters, keeping energy efficiency in mind to give you the most energy savings. The unique solid polymer material Polywood is made from is dense enough to block air flow. This results in shutters that are a natural insulator. You can block more temperature and light than any other shutter by sealing the weather-stripping pieces on the sides of the shutter. This greatly reduces heat transfer at the edge of the panels in both the heat of summer and the cold of winter in Kingsport. Top that off with a heat-reflective paint, and you have a shutter that is not only stunning but also exceptionally energy efficient. As a matter of fact, Polywood shutters insulate up to 70% better than an equivalent 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 brings you more energy savings than any other shutter: Stops Air Flow. Polywood’s thermal protection blocks as much as 30 degrees of airflow that passes through a window. Maximizes R-Value. Polywood’s R-Value is over 6 in a double-pane window. That’s the highest thermal resistance rating of insulation material of any shutter on the market. Reduces Heat Transfer. Polywood offers 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 the humid conditions that can impact the temperature of a room. The Polywood Shutter Insulating System incorporates all of these energy-efficient benefits to save you actual dollars on your energy statements. No other shutter looks as beautiful, lasts as long, or saves you as much on your energy bills as our Polywood shutters. Learn more about Polywood shutters.
