The Polywood Shutter Insulation System The most energy-efficient window treatment is shutters. And our Polywood shutters, with their exceptional insulation system, are the best energy saving shutters in Denver – if not America. We construct each component of our Polywood Shutters, keeping energy efficiency in mind to give you the most energy savings. The exclusive solid polymer material Polywood is made from is thick enough to block air flow. This results in shutters that are a natural insulator. You can block more light and temperature than any other shutter by sealing shut the weather-stripping pieces on the sides of the shutter. This greatly limits heat transfer around the panels in both the hot summer and the cold winter in Denver. We add in a heat-reflective paint, and you get a shutter that is not only stunning but also exceptionally energy efficient. In fact, Polywood shutters insulate up to 70% better than a similar 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 long. Here’s how Polywood provides you with more energy savings than any other shutter: Blocks Air Flow. Polywood’s thermal protection blocks up to 30 degrees of airflow that goes 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 on the market. Reduces Heat Transfer. Polywood leads to 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 moisture and humidity that can impact the temperature of a room. The Polywood Shutter Insulating System integrates all of these energy-efficient qualities to save you actual dollars on your energy bills. No other shutter looks as elegant, lasts as long, or saves you as much on your energy bills as our Polywood shutters. Learn more about Polywood shutters.
