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 Charlotte – if not America. We carefully construct every part of our Polywood Shutters, keeping energy efficiency in mind to give you the most energy savings. The specialty solid polymer material Polywood is made from can block airflow because of its density. This transforms these shutters into a natural insulator. You can block more light and temperature than any other shutter by sealing 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 Charlotte. Add to that a heat-reflective paint, and you get a shutter that is not only beautiful but also remarkably energy efficient. As a matter of 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 long. Here’s how Polywood provides you with more energy savings than any other shutter: Blocks Air Flow. Polywood’s thermal protection blocks as much as 30 degrees of airflow that passes 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 in the industry. Reduces Heat Transfer. Polywood offers 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 moisture and humidity that can affect the temperature of a room. The Polywood Shutter Insulating System incorporates all of these energy-efficient benefits to save you money on your energy bills. No other shutter looks as elegant, is as durable, or saves you as much money as our Polywood shutters. Learn more about Polywood shutters.
