The ENTIRE Aeratis family of products are engineered for both covered and uncovered applications. The transition between covered and uncovered porches has been tricky in the past. There is a difference in surface temperature and weathering on different parts of the porch throughout the day as the sun passes through the sky. Then when it rains, snows or freezes this poses a completely different challenge to the surface. All of these influences can affect the appearance of your porch. Rest assured, we have you covered! We are aware of the challenges that having a partially covered and uncovered porch can pose. We’ve engineered a product that we are happy to stand behind, with our full warranty, for both covered and uncovered applications.
