In business since 1966, Patio Enclosures, Inc. is the nation's largest manufacturer & installer of sunroom related products. All products are designed and engineered to be accepted by local building codes. Being a custom manufacturer means no limitation to just "stock" sizes, but rather an unlimited array of shapes and sizes. Also, several roof options are available, including our patented Comfort-Gard® glass roof panel, which is an integral part of the roof system, adding volumes of natural light to the space.
