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 Diego – if not the US. We take care to make each part of our Polywood Shutters, keeping energy efficiency in mind so you can reap the energy savings. The unique solid polymer material Polywood is manufactured from can block airflow because of its density. 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 greatly limits heat transfer around the panels in both the summer heat and winter cold in San Diego. We add in 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 gives you more energy savings than any other shutter: Stops Air Flow. Polywood’s thermal protection blocks as much as 30 degrees of airflow that comes 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 in the industry. Reduces Heat Transfer. Polywood leads to 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 the humid conditions that can affect the temperature of a room. The Polywood Shutter Insulating System incorporates all of these energy-efficient features to save you money on your energy statements. No other shutter looks as elegant, lasts as long, or saves you as much money as our Polywood shutters. Learn more about Polywood shutters.
