Screen Room vs. Sunroom vs. Florida Room: Which Do You Actually Want?

People use these three words like they mean the same thing, and then get a quote that's three times what they expected — or a room that doesn't do what they wanted. So before you call anyone, here's the honest breakdown of what you're actually choosing between.

What a screen room is

A screen room is an aluminum frame with screen panels, built onto your patio, deck, or slab. No glass. It's open-air by design — breeze comes through, bugs don't.

What it's for:

• Sitting outside in the morning and evening without getting eaten alive
• Keeping leaves, pollen, and debris off a patio or pool deck
• Adding usable space fast and at the lowest cost of the three

What it is not: a room you can heat or cool. There's no glass to seal it, so it's the same temperature as outside. On a still August afternoon, a fan helps and the shade helps, but it's still a Florida afternoon. If you've already got a roof over the space, screening in the sides — walls under an existing cover — is the fastest, cheapest version of this.

Sunroom vs. Florida room

Here's the part that trips people up: a sunroom and a Florida room are basically the same thing. “Florida room” is the older regional term; “sunroom” is what the rest of the country says. Both mean a room with glass or vinyl walls, enclosed against the weather, that can be climate-controlled.

The real dividing line isn't the name — it's whether the room is under air:

• Not under air: glass or vinyl walls, sealed against rain and bugs, but no HVAC. Comfortable most of the year, hot in peak summer.
• Under air: tied into your home's heating and cooling (or its own unit). Now it's true year-round living space — and typically counts as heated square footage, which matters for resale.

Either way, a sunroom is a bigger build than a screen room: glass, sealing, insulation, and — if it's under air — HVAC work and stricter permitting under the Florida Building Code. That's a different trade from what we do.

The real trade-offs

The honest comparison, without the sales gloss:

• Cost: Screen room is the cheapest by a wide margin. A sunroom not under air is a big step up. A sunroom under air is the most expensive, because you're adding HVAC.
• Summer use: Only the under-air sunroom is genuinely comfortable at 3pm in August. The other two are shade-and-breeze spaces.
• Bugs and airflow: A screen room breathes — that's the whole point. A sunroom seals out weather but also seals out the breeze.
• Permitting: All three are permitted structural work here (see do you need a permit), but a sunroom under air pulls in mechanical and energy code on top of the structure.
• Resale: A permitted, under-air sunroom can add heated square footage. A screen room adds usable outdoor living for a fraction of the money. Which one “wins” depends entirely on your budget and how you'll use it — the efficiency of the glass and HVAC matters a lot if you go the sunroom route.

Which one you actually want

Match the room to how you'll really use it:

• “I want to enjoy my patio without bugs, morning and evening.” → Screen room. Don't spend sunroom money on a problem screen solves.
• “I want to keep my pool clean and screened.” → A pool cage, which is a screen room around the water.
• “I already have a covered porch, I just want it closed in.” → Screen the sides — walls under.
• “I want a real room I can use with the AC on in July.” → Sunroom under air. That's not us — and we'll say so rather than sell you a screen enclosure that won't do it.

That last one is the whole reason we wrote this. Plenty of homeowners come to us wanting a screen room when they describe a sunroom, or the other way around. We would rather lose the sale than build you the wrong room — it's the same standard we hold on everything, which you can read about on why homeowners hire us.

FAQ

Is a screen room cheaper than a sunroom?

Yes, considerably. A screen room is aluminum frame and mesh. A sunroom adds glass or vinyl walls, sealing, and often HVAC — each of which adds cost. If budget is the driver and you don't need air conditioning, the screen room is the call.

Can I use a screen room in a Florida summer?

In the shade, with a fan, mornings and evenings — comfortably. What you can't do is cool it, because it's open-air. If you want a 72-degree room on an August afternoon, that's a sunroom under air.

What's the difference between a sunroom and a Florida room?

Mostly just the words. “Florida room” is the older local term and “sunroom” is the national one. Both mean an enclosed, glass-walled room. Treat them as the same category when you're comparing against a screen room.

Does a screen room or a sunroom add more home value?

A permitted, under-air sunroom generally adds measurable heated square footage. A screen room adds usable outdoor living at a fraction of the cost. Neither is automatically “better” — it depends on your budget and how you'll use the space.

Do you build sunrooms too?

We build screen rooms, pool cages, patio covers, and the related work. A full glass sunroom under air is a different trade. If that's what you actually want, we'll tell you and point you the right direction — call (904) 862-8688 and we'll talk it through either way.
