The Polywood Shutter Insulation System The most energy-efficient window treatment is shutters. And our Polywood shutters, with their advanced insulation system, are the best energy saving shutters in Raleigh – if not America. We take care to craft every part of our Polywood Shutters with energy efficiency in mind so you can enjoy the energy savings. The exclusive solid polymer material Polywood is manufactured from is dense 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 the weather-stripping pieces on the sides of the shutter. This greatly limits heat transfer at the edge of the panels in both the hot summer and the cold winter in Raleigh. Add to that a heat-reflective paint, and you have a shutter that is not only stunning but also remarkably 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 hard. Here’s how Polywood brings you more energy savings than any other shutter: Shields Against Air Flow. Polywood’s thermal protection blocks up to 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 on the market. Reduces Heat Transfer. Polywood results in 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 humidity and moisture that can affect a room’s temperature. The Polywood Shutter Insulating System combines all of these energy-efficient benefits to save you money on your energy bills. No other shutter looks as exquisite, lasts as long, or saves you as much on your energy bills as our Polywood shutters. Learn more about Polywood shutters.
