What makes polywood better than the competition?

It starts with our unique material that is dense enough to block air flow. The sides of our shutters have weather-stripping that block more temperature and light than any other shutter. This weather-stripping is also on our decorative frame. Finally, with UV inhibitors in both the material and baked into the paint finish, Polywood stands up to even the most intense sunny climates.
