The Polywood Shutter Insulation System Shutters are the top energy-efficient window treatment. And our Polywood shutters, with their progressive insulation system, are the best energy saving shutters in Honolulu – if not the US. We carefully make 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 manufactured from is thick enough to block air flow. This makes 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 effectively limits heat transfer at the edge of the panels in both the heat of summer and the cold of winter in Honolulu. Add to that a heat-reflective paint, and the result is a shutter that is not only stunning but also exceptionally 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 gives you more energy savings than any other shutter: Shields Against Air Flow. Polywood’s thermal protection blocks up to 30 degrees of airflow that goes 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 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 influence a room’s temperature. The Polywood Shutter Insulating System combines all of these energy-efficient qualities to save you actual dollars on your energy bills. 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.
