Autumn Exteriors Premium Vinyl Siding features a patented mid-panel lock design that pulls panels tight to the wall and provides enhanced panel rigidity. With beautiful colors and designs to compliment your home. We even have the look of freshly painted wood, without all the maintenance. The unique lock design delivers twice the holding power of ordinary vinyl siding. And the extra-thick panels mean straighter, smoother, more even walls. With its unique locking system our siding is built to withstand heavy wind and storms. In wind resistance tests, this siding stayed locked in place at wind forces exceeding 150 miles per hour.
