Room Additions All Season Three Season Rooms 12


Three-season and all-season rooms are a fantastic addition to your home, extending your enjoyment of the outdoors beyond the spring and summer months. They also add curb appeal and value to your home.

Since there are some major differences between these two rooms, it’s important to first establish how you’d like to use your additional room before choosing a three- or all-season room. And if you’re not quite sure, Legacy Exteriors can help you determine exactly what’s best for you, your home, and your budget.

Three-season Rooms
Typically used in the spring, summer and fall, three-season rooms are constructed with single-pane glass, non-insulated floors and non-thermally-engineered frames. Because of this, they do not offer the same degree of climate control as an all-season room, which is why they’re not suited for Wisconsin winters. Some homeowners do occasionally use space heaters to enjoy their three-season room during winter, it’s just not a cost-effective option for long term use.

That said, they’re built to last — and look good — for years!

A three-season room is an ideal choice if you only plan on using your new home edition during the more mild months. Your cost will be lower, as opposed to an all-season room,  and the view will be just as stunning!

Our three-season rooms are highly customizable, and we can work with you to ensure it suits your style, and your budget, perfectly.

We offer Four Seasons three-season rooms — including the lovely Crystal View Florida Room (pictured here).

All-season Rooms
As you may have guessed, an all-season room can be used 365 days a year, keeping you cozy on the coldest or warmest of days. Double-pane glass, insulated floors and thermally engineered framing provides cost-effective heating and cooling year round.

Just like our three-season rooms, our all-season rooms are built to last and look good for years — and they’re also customizable so you can choose the exact aesthetic you’re looking for.

If you’d like to enjoy nature, entertaining, or simply want to relax surrounded by nature all year long, an all-season room is a fantastic choice.
