Differences Between a 3 Season Room vs. 4 Season Room

While the most obvious answer to this question would appear to be one season-there’s a little bit more to it than that.  In this blog, we’ll clarify the differences between a 3 season and 4 season room so if you’re in the market for one you’re able to make an educated decision on what type of sunroom or deck and patio enclosure is best for your home.

What Is A 3 Season Room?

A three season room is designed for use in spring, summer and fall but cannot be utilized in the winter due to the fact that it is not connected to your home’s HVAC system which prevents its temperature from being regulated.  4 season rooms have more insulation than 3 season rooms (which in some cases have no insulation).  A four season porch must follow the same codes (floor, wall, ceiling, insulation, windows, etc.) as a standard room addition.

What Is A 4 Season Room?

A four seasons room has more insulation than 3 seasons rooms (which in some cases have no insulation.  A four season porch must follow the same codes (floor, wall, ceiling, insulation, windows, etc.) as a standard room addition.

Perks of Each Sunroom

Three Season Room

  • Keeps pollen, dust, dirt, direct sunlight, rain & mosquitoes out of your entertaining
    space
  • Less costly than a 4 season room since it is not temperature regulated
  • Can be constructed quicker

Four Seasons Room

  • A year-round entertaining space
  • Increases your property’s value more than a 3 season room does
  •  4 season rooms are often filled with windows which gives the vibe of being outdoors without having to leave an air conditioned or heated area

Drawbacks of Each Sunroom

Three Season Room

  • Can’t be used year-round
  • Adds less value than a four season room

Four Season

  • More expensive
  • Takes longer to construct

"Lindus has been our go-to construction business for our gutters, deck, & 2 storm repair jobs, one with significant late season damage. They managed to fit us into their schedule to get our roof & deck repaired before winter set in. Their people are reliable & easy to work with, especially when storm insurance is involved. While they may be a bit more expensive, they use high quality materials & stand behind their work. You won't be disappointed!"

"We wanted to say how pleased we were with the restoration of our upper and lower decks especially the deck that supports the elevated porch. Dave and Joe never hesitated to go the extra mile during the construction phase. So, this would be a good report."
