Asunroom, also frequently called asolarium (and sometimes a "Florida room", "gardenconservatory", "garden room", "patio room", "sun parlor", "sun porch", "three season room" or "winter garden"[1]), is a room that permits abundantdaylight and views of thelandscape while sheltering from adverse weather.Sunroom andsolarium have the same denotation:solarium isLatin for "place ofsun[light]". Solaria of various forms have been erected throughout European history. Currently, the sunroom or solarium is popular inEurope,Canada,[2] theUnited States,Australia, andNew Zealand. Sunrooms may featurepassive solar building design to heat and illuminate them.[3]
InGreat Britain, which has a long history of formalconservatories, asmall conservatory is sometimes denominated a "sunroom". In gardening, agarden room is a secluded and partly enclosed outside space within a garden that creates a room-like effect.

Attached sunrooms typically are constructed of transparenttemperedglazing atop a brick or wood "knee wall" or framed entirely of wood, aluminum, orPVC, and glazed on all sides.Frosted glass orglass block may be used to add privacy. Screens are a fundamental aspect of a "Florida room", andjalousie windows are often featured. An integrated sunroom is specifically designed with many windows and climate controls.

A solarium is typically distinguished from a sunroom by the former being specifically and primarily designed to collect sunlight for warmth and light as opposed to being primarily designed to feature scenic views, and by being composed of walls, save one, and a roof that are entirely of framed glass. These typically are erected in higher latitude (low angle of sunlight) or cold (higher altitude) locations. In contrast, a sunroomsensu stricto has an opaque roof.[4]
During the 1960s, professional re-modelling companies developed affordable systems to enclose a patio or deck, offering design, installation, and full servicewarranties. Patio rooms featured lightweight, engineered roof panels, single pane glass, andaluminium construction.[citation needed]
As technology advanced,insulated glass,vinyl, and vinyl-wood composite framework appeared. More recently, specialized blinds and curtains have been developed, many electrically operated byremote control.[5] Specialized flooring, includingradiant heat, may be adapted to both attached and integrated sunrooms.
