Three Season Porch vs Four Season Porch

Three Season Porch

Sturdier than your average screened in porch or enclosed deck, a 3-season room addition is a good option for homeowners who want to enjoy outdoor living in style but who don’t need the living space available all year long. 3 season rooms are:

• Used primarily spring, summer and fall
• Often added to an existing deck or patio with a few structural changes
• Separated from the rest of the house with an exterior door
• Heated and cooled separately from the home, if at all
• Not insulated
• Generally completed within a week

A 3-season porch has windows with integrated screen systems and can be used for long periods throughout the year. They can shield you from outdoor elements such as rain, wind, sun and insects, but 3-season porches are not heated. Therefore, it is not a part of finished square footage, but is considered an enclosed space.

Economical

One of the biggest benefits to a three-season porch is the fact that it is very economical. Since it is not heated or cooled, it costs much less to build than a four-season porch or room addition would. It also does not require any additional money to heat or cool this space. Maintenance costs are very minimal as well.

Four Season Porch

A 4-season porch (also known as an all season room or sun room) is a room that functions as an interior room, but allows you to take in the views of the outdoors year-round. It has permanent heat and is included in the finished square footage of the home.

A 4 season room, also referred to as all-season or year round room, is integrated into the construction of your home, existing roofline and exterior. This structure is:

• Constructed to use your existing HVAC for year round usage
• Open to the rest of the house
• Constructed with insulated, walls, floor and roof
