And, when combined with Solar Gard window film, Polywood shutters are the prime choice for the most savings on your energy payments. 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 San Antonio – if not America. We carefully craft every part of our Polywood Shutters with 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 transforms these shutters into 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 dramatically reduces heat transfer at the edge of the panels in both the hot summer and the cold winter in San Antonio. Add to that a heat-reflective paint, and you have a shutter that is not only beautiful but also extremely 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 in the industry. 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 the humid conditions that can affect a room’s temperature. The Polywood Shutter Insulating System combines all of these energy-efficient qualities to save you actual dollars on your energy statements. You won’t find another shutter that looks as beautiful, is as durable, or saves you as much money as our Polywood shutters. Learn more about Polywood shutters.
