top >> Q. What is the difference between a 3 and 4-Season sunroom?
A. The 3-Season room is constructed with 2″ think wall panels having the 3-Season Vinyl glazed or single pane glass windows. These rooms extend living space “3 seasons” of the year where efficient heating is not needed year round. The 4-season room has 3″ thick wall panels thermally broken to allow for efficient heating and cooling the whole year. Insulated glass is used in the “all-season” room or an upgrade in the 3-season room.
