What is the difference between three-season and four-season outdoor rooms? Three-season porches, as the name implies, can be used in as many seasons per year (particularly spring, summer and fall); and although they may be insulated, they are not designed to be heated during winter months. Three-season rooms in theory offer the best of both worlds: Acting as a buffer between your home and your yard, the rooms can be used for everything from curling up by the fire to an exercise room or hot tub. Keep in mind, though, that everything in this room will be exposed to the elements; therefore, all materials must be able to withstand freezing elements.

Four-season rooms, on the other hand, are more utilitarian; enclosed porches may be used 12 months out of the year and provide comfort during the harsh months of Midwestern winters. These rooms are generally an extension of the home’s architectural style and are as thermally efficient as the rest of the home thanks to insulated glass and wall panels that allow for efficient heating and cooling throughout the year.
