A sunroom is a basic room addition that has more windows than your average room and a solid, foam-insulated panel roof that is similar to that of a mobile home. Sometimes called porch enclosures, sunrooms typically feature a shed-style or studio-style roof. Sunrooms are sometimes referred to as solariums, conservatories, patio rooms, and green rooms, depending on how they are is being used. It can be an addition to your kitchen or family room, a glassed-in porch or deck, or a separate structure that acts as an extension of your home with its own entry and exit.
