The Polywood Shutter Insulation System Shutters are the most energy-efficient window treatment. And our Polywood shutters, with their progressive insulation system, are the best energy saving shutters in Austin – if not the US. We craft each part of our Polywood Shutters with energy efficiency in mind to give you the most energy savings. The exclusive solid polymer material Polywood is composed from is thick enough to block air flow. This results in shutters that are 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 greatly limits heat transfer at the edge of the panels in both the cold of winter and the heat of summer in Austin. Add to that a heat-reflective paint, and you get a shutter that is not only stunning but also extremely energy efficient. As a matter of 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: Stops Air Flow. Polywood’s thermal protection blocks up to 30 degrees of airflow that goes 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 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 moisture and humidity that can affect the temperature of a room. The Polywood Shutter Insulating System integrates all of these energy-efficient qualities to save you money on your heating and cooling bills. No other shutter looks as beautiful, lasts as long, or saves you as much money as our Polywood shutters. Learn more about Polywood shutters.
