Choosing Between a Three Season and a Four Season Room

Room additions can be the perfect way to increase space, make your home more functional, or add to your property value. Sunrooms provide a space for your family and guests to relax and enjoy the outdoors while remaining in a comfortable environment, and hiring a custom home builder to add a three season or four season room to your Duxbury home is an excellent investment. The suitability of three season versus four season homes depends on climate and the preferences of the homeowner.

What's the Difference?

The primary difference between three season and four season rooms built by a custom home builder is that the types of glass and framing used for four season rooms provide sufficient insulation from the outdoors, allowing the four season room to be temperature controlled all year. Three season rooms constructed by a custom home builder are usually functional only in the spring, summer, and fall.

Three Season Rooms

  • Aluminum framing that is not designed to retain heat
  • Single-pane or double-pane glass options
  • Lacks insulation
  • Triple track system with ball-bearing wheels
  • Cooled and heated separately from the house or not at all
  • More affordable than four season rooms

Four Season Rooms

  • Vinyl and aluminum framing options that are thermally engineered to insulate the room all year
  • Monorail system with ball-bearing wheels
  • Double-pane glass options
  • Designed to utilize your current HVAC system
  • More expensive than four season rooms

Although four season rooms are better at managing temperature because of their insulating capabilities, a four season room will likely cost more than a three season room. Depending on your needs and preferences, a three season room may be perfectly suitable for your home. If you need more help deciding which type of sunroom is best for you, discuss the characteristics of each type with an experienced Duxbury custom home builder like VBuilt Custom Homes.
