From the Studio Roof model, you can upgrade to extend the season of your patio room to either a Model 3500 extended season patio room or the Model SRC V3 four-season sunroom.  The patio room is a smart choice with a fully-transferable Limited Lifetime Warranty, 2½” wall system, energy-efficient ½” double-pane tinted insulated glass, unlimited custom wall colors, Internal Electrical Raceway System, and aluminum sliding windows featuring tempered glass and double locks.  If you choose the Sun Room, you can customize many of the options, including colors of windows and grids in the patio door.
