If you are to actually point out one difference between a three and a four season sunroom, it’s pretty obvious—one season! While the three season room is for the warmer months, the four season allows the sunroom to be used comfortably year-round. Patio Solutions in East Rochester, NY, lists the differences between these two sunrooms.

Differences Between 3 and 4 Season Sunrooms

Glass

Glass is the most important component of a sunroom and its make plays a major role in the entire scheme of things. Single pane tempered glass windows are used in a three season room for minimal energy efficiency while in a four season room, high energy efficient windows are used. The difference is also clear when high quality glass is used. Heat loss during winter is reduced considerably when superior quality glass is used and keeps excessive heat and ultraviolet rays at bay during the summer.

Insulation

Insulation plays a very important role in the entire heating of the house and more so when it comes to the sunroom. Insulation of walls, roof, and floor are important in the extended use of the sunroom. The amount and quality of insulation makes a big difference between a sunroom for three and four seasons. What helps keep the heat in the winter months and extend the usability is the additional insulation found in the walls, roof, and floor. 

HVAC Unit

The HVAC unit works differently for a three and four season sunroom as well. For a three season sunroom, it can’t really keep the room heated during winter as it lacks sufficient insulation, whereas, it is used effectively for heating or cooling in four season room year round.
