A four seasons room is a type of sunroom that is enclosed with glass, which allows for breathtaking floor-to-ceiling views of the outdoors. The roof and frames of these sunrooms are thermally engineered so that the room can be heated and cooled year-round, making it a true extension of your home. The main distinguishing factors between a three-season room and a four-season room are the framing system and glass used. A four-season room is designed to be heated and cooled cost-effectively, year-round, regardless of the weather, while a three-season room is typically only used in the spring, summer, and fall when outside temperatures are mild. Here are some key differences between three-season and four-season rooms:

• Usability: A four-season room can be used all year, whereas a three-season room does not have the same heating and cooling capacity and thus is not usable in too hot or too cold climates.

• Engineering and Materials: A four-season room typically has dual insulated glass panes installed to help prevent airflow, whereas a three-season room typically has single-pane glass installed. Four-season rooms are created with thermally engineered extruded aluminum or structurally reinforced vinyl, while three-season rooms are constructed with a powder-coated aluminum frame.

• Frame: A four-season room will always have an entry door from the existing house, while a three-season room may or may not have an entry door.

• Cost: Four-season rooms use superior quality materials, adding to the rooms additional construction. As a result, a four-season room estimate requires a larger investment than a three-season room estimate.

Overall, a four-season room is a great option if youre looking for a room you can enjoy year-round, as it offers breathtaking views of the outdoors and can be heated and cooled cost-effectively.
