The Polywood Shutter Insulating System has been proven to have the highest R-Value, best thermal protection, best reduction of heat transfer, and offer the most energy efficiency of any shutter on the market.
A 3rd party thermal test showed that Polywood blocks as much as 30 degrees of temperature coming through the window. And that makes for the most energy efficient shutter in the industry.
