Three-Season Rooms

Three-season
rooms

Built onto your
deck or patio

We build Suncoast’s 3 Season Room onto your existing deck or patio, attached to the house: a powder-coated aluminium frame, a polycarbonate roof, and vinyl windows over permanent screens.

Vinyl windows on a four-track system that open up to 75% of the space.
A permanent exterior screen keeps insects out with the windows open or closed.
Clear or smoke-tinted vinyl, with fixed transom panels where a sliding window does not fit.

What’s
included

Aluminium frame

Structural, powder-coated aluminium framing, sized to your space.

Polycarbonate roof

Twin-wall panels in clear, opaque or heat-reflective, on a shed, gable or mansard roofline, rated for heavy snow.

Sliding vinyl windows

Clear or smoke-tinted vinyl on a four-track system, with fixed transom panels for the shapes a sliding window can’t fill.

Screens built in

High-strength fiberglass screens at 90%, 55% or 15% outside the windows.

FAQ

Frequently asked
questions

What is a three-season room?

A weatherproof, insect-free room built onto a deck or patio and attached to the house, with sliding vinyl windows over permanent screens.

Are the windows glass?

No. Suncoast uses clear or smoke-tinted vinyl. The windows slide vertically on a four-track system, so you can open up to 75% of the space.

How does it stand up to a Midwest winter?

The frame is powder-coated aluminium and the twin-wall polycarbonate roof is rated for heavy snow loads.

Can you build one onto my existing deck or patio?

Yes — that is how they are designed. Each room is sized to the deck or patio it sits on, and if the space already has a roof, Suncoast’s 3 Season Walls can enclose it under the roof you have.

Why Suncoast?

As an authorized Suncoast dealer serving Omaha, Kansas City, Lake of the Ozarks, and the broader Midwest, Beyond Blue installs each pergola, louvered roof, and retractable screen with hands-on precision.

Do I need permits, and will you handle them?

Yes. Most enclosure projects require structural and electrical permits, and many municipalities have specific requirements for pool enclosures. We handle all permitting as part of the project, so you do not need to navigate the process on your own.
