Three Season Sunrooms

Three Season Sunrooms and Solariums

Details:  Three Season Sunrooms and Solariums have most of the benefits of Four Season rooms at a fraction of the cost.  Low cost is the main reason they’re so popular.  They can be built on existing decks and patios.  They can be built without kneewalls or with privacy panels on gable ends.

Commom Usage:  Three Season Sunrooms are commonly used for three and a half seasons (10.5 months).   You’ll have a relaxing place to reduce stress, entertain friends and family, soak in your hot tub, host social events, birthdays, holiday entertaining, play your instrument or just cozy up to a good book or podcast.  Three Season Sunrooms are also used to extend the growing season for home gardeners.

Construction:  PVC and Aluminum Construction.  Straight or curved glass.  The construction is designed to be maintenance-free so there is no need to paint, stain or annually maintain your sunroom.

Options:  Acrylic, Polycarb with Heat-Guard and other high-tech features.

Pros:  Costs much less than four season rooms with almost all the benefits for four season rooms.  The three season addition is not considered a permanent addition to your home, thus not subject to increased taxes in most provinces (please verify in your province).

Enjoy lower heating and cooling costs since it is a seasonal room.  Depending on your flooring, three season rooms can often be used for three-and-a-half seasons meaning they are used for 10.5 months of the year.

Acrylic glazing is rated better than glass for insulating factors.  Even single glazing acrylic won’t fog up as glass windows do on cold evenings.

Can be built on existing patios.  However, existing decks may be altered to meet codes.  New or insulated decks can be supplied.

The build time is 4-5 days on an existing deck.  2 weeks for a new deck and build.

Cons:  Not insulated the same way as a four season room so it can’t be used year-round.

Price Range [Updated for 2024]:  Three Season Rooms are very reasonably priced.  They often range from $55k – $80k depending on options such as decking, flooring, siding and number of window/door openings.
