Our Polywood® Shutter Insulating System has exceptional thermal resistance, the best reduction of heat transfer, and offers the most energy efficiency of all the window treatments available. And, when paired with Solar Gard window film, Polywood shutters are the best choice for maximum savings on your energy payments.
 
 

The Polywood Shutter Insulation System 

Shutters are the top energy-efficient window treatment. And our Polywood shutters, with their exceptional insulation system, are the best energy saving shutters in Dover – if not America.
 
We take care to make every component of our Polywood Shutters with energy efficiency in mind so you can reap the energy savings. The exclusive solid polymer material Polywood is manufactured from is thick enough to block air flow. This transforms these shutters into a natural insulator. Polywood shutters block more temperature and light than any other shutter because of their patented weather stripping on the sides of each shutter panel. This dramatically limits heat transfer around the panels in both the hot summer and the cold winter in Dover. Top that off with a heat-reflective paint, and the result is a shutter that is not only timeless but also remarkably energy efficient. In fact, Polywood shutters insulate up to 70% better than an equivalent wood shutter.
 
Shutter Energy Efficiency
 
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 brings you more energy savings than any other shutter:
  • Shields Against Air Flow. Polywood’s thermal protection blocks as much as 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 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 impact the temperature of a room.
