3 Season Porch Enclosure Installation in Oklahoma — Vinyl or Glass Windows, You Choose
Oklahoma’s weather is beautiful – until it isn’t. One week it’s perfect porch weather, the next it’s 105 degrees, thunderstorms, and mosquitoes. A 3 season porch enclosure lets you enjoy the outdoor experience on your terms, shielded from heat, rain, wind, bugs, and UV.
Sunspace by Express Sunrooms of Oklahoma installs 3 season porch enclosures across the entire state of Oklahoma using the proven Sunspace system — 2-inch foam-insulated aluminum wall panels, custom-built to your exact dimensions, with your choice of two window styles. The WeatherMaster vinyl sliding window system (Model 200) and the single-glazed glass double roller window system (Model 300) both use the same high-quality frame and wall construction. The choice simply comes down to the window glazing that’s right for you.
What Is a 3 Season Porch Enclosure?
A 3 season porch enclosure transforms an open deck, porch, or patio into a fully enclosed living space with windows that open and close on demand. It gives you fresh air and views when you want them, and solid weather protection when you don’t. Unlike a screen room (bugs only), a 3 season enclosure has insulated walls and weather-rated windows that seal against rain, wind, and cold. Unlike a 4 season sunroom, it is not designed for full HVAC year-round — making it a more affordable, faster option for most Oklahoma homeowners.
Best for: Extending your porch season from early spring through late fall, adding real weather protection without a full home addition, keeping bugs and storms out while still enjoying the outdoors, and adding high-ROI usable square footage to your home.


Choose Your Window Style — Vinyl or Glass
Both options use the same 2-inch foam-insulated aluminum wall panels and sturdy extruded aluminum frame. The difference is in the window glazing.
Option 1 — WeatherMaster Vinyl Windows (Model 200)
The WeatherMaster 4-Track Vinyl Window System is our most popular choice. Each panel slides up or down on four tracks, opening up to 75% for maximum ventilation or closing completely to seal out rain and wind. Made from resilient ViewFlex glazed vinyl — flexible, hail-resistant (won’t shatter), and UV-stabilized to resist yellowing.
Window tint options: Clear, Smoke Grey, Dark Grey, Bronze.
Best for: Homeowners who want tinted glazing to control Oklahoma’s heat and glare, hail resistance, and maximum ventilation flexibility.


Option 2 — Single-Glazed Glass Windows (Model 300)
The Model 300 uses aluminum-framed, single-glazed glass with a double roller window system. Both sashes are operational with no fixed side — ventilation from both the top and bottom of each window. Glass delivers superior optical clarity: sharper, cleaner views than vinyl. Available with multiple roof system options including cathedral ceilings and modern studio pitch roofs. Installs over existing decks, porches, or carports.
Best for: Homeowners who prioritize crystal-clear views, a traditional window appearance, or want cathedral/studio pitch roof design options.

Three options: 4-½” (R-17), 6-½” (R-26), 8-¼” (R-35). Panels use Engineered OSB over foam core — ready for carpet, tile, hardwood, or laminate. Also suitable as a roofing substrate with finished ceiling inside.

Frequently Asked Questions
What is the difference between a 3 season porch enclosure and a 4 season sunroom?
A 3 season porch enclosure (Model 200 or 300) is designed for spring, summer, and fall use. It provides excellent weather protection but is not designed for full HVAC heating and cooling year-round. A 4 season sunroom (Model 400) uses Low-E Argon glass, 3-inch thermal panels, and commercial-grade thermal breaks to support year-round climate control.
Should I choose vinyl or glass windows?
Choose vinyl (Model 200) for tinted glazing options, hail resistance, and maximum ventilation control up to 75%. Choose glass (Model 300) for crystal-clear views, a traditional window look, or cathedral/studio pitch roof options. Both provide equal weather protection.
Can this be built over an existing deck or carport?
Yes. Both models install over existing decks, porches, and carports. Our consultants evaluate your structure during the free in-home visit.
What roof styles are available?
The Model 300 supports cathedral ceilings and studio pitch roofs. Model 200 roof options vary by configuration and are reviewed during your free consultation.
Can I upgrade to a 4 season sunroom later?
The Sunspace system is designed for upgrades. The Model 100 screen room upgrades directly to Model 200 vinyl windows. Upgrades from Model 200/300 to Model 400 are evaluated case-by-case.
How long does installation take?
Most installations complete in one to three days. Permitted projects may take slightly longer.
