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 Indianapolis – if not the US. We take care to craft each part of our Polywood Shutters, keeping energy efficiency in mind to give you the most energy savings. The specialty solid polymer material Polywood is composed from can block airflow because of its thickness. This transforms these shutters into a natural insulator. There are weather-stripping pieces on the sides of the shutters that seal shut to block more temperature and light than any other shutter. This dramatically reduces heat transfer at the edge of the panels in both the hot summer and the cold winter in Indianapolis. Top that off with a heat-reflective paint, and you have a shutter that is not only stunning but also remarkably energy efficient. In 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 hard. 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 comes 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 you can find. Reduces Heat Transfer. Polywood leads to a 45.96% reduction in heat transfer. Boosts 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 qualities to save you actual dollars on your energy statements. You won’t find another shutter that looks as exquisite, lasts as long, or saves you as much on your energy bills as our Polywood shutters. Learn more about Polywood shutters.
