This nice looking patio cover is made by a German company called Acrylite. It has a dual wall acrylic roof panel and all aluminum frame. It comes with a ten year warrantee and there are no penetrations through the roof, so there is no way it can leak. The aluminum T bars clamp down on the panels to hold them in place. It is installed over the roof of the home with Skylifts which raise the patio cover up and allow the home’s roofing to be replaced at a later date independent of the patio cover. This particular patio cover has a brown frame and bronze color acrylic panels. It is a very classy look and will last a lifetime.
