And, when paired with Solar Gard window film, Polywood shutters are the prime choice for maximum savings on your energy statements. The Polywood Shutter Insulation System Shutters are the most energy-efficient window treatment. And our Polywood shutters, with their advanced insulation system, are the best energy saving shutters in San Jose – if not the United States. We take care to make every component of our Polywood Shutters with energy efficiency in mind to give you the most energy savings. The exclusive solid polymer material Polywood is manufactured from is thick enough to block air flow. This results in shutters that are a natural insulator. The sides of the shutters have weather-stripping pieces that seal to block more light and temperature than any other shutter. This effectively reduces heat transfer at the edge of the panels in both the summer heat and winter cold in San Jose. Top that off with a heat-reflective paint, and you get a shutter that is not only timeless but also remarkably energy efficient. In 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 hard. Here’s how Polywood provides you with more energy savings than any other shutter: Stops Air Flow. Polywood’s thermal protection blocks as much as 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 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 humidity and moisture that can impact a room’s temperature. The Polywood Shutter Insulating System integrates all of these energy-efficient features to save you actual dollars 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.
