Transform your porch, deck, or patio into a room you use every day.
Sunspace by Express Sunrooms of Oklahoma installs custom sunrooms for Oklahoma homeowners who want outdoor scenery, natural light, and fresh air — without the heat, insects, wind, and storms that make a standard porch or patio nearly unusable for most of the year.
Oklahoma summer heat peaks above 100 degrees for weeks at a stretch. Spring tornado season arrives just when the weather turns pleasant. Mosquito and cicada season runs from late April through October. A custom sunroom solves all three problems in one installation.
High-density construction with heavy-gauge aluminum extrusions for structural rigidity and moderate insulation.
Panels slide up, down, or stack center — opening to 75 percent ventilation.
More durable than glass, lighter, virtually maintenance-free, and time-tested for over 40 years.
Clear, Smoke Gray, Dark Gray, and Bronze — matched to your porch orientation and OKC sun exposure.
4.5" (R17), 6.5" (R26), or 8.25" (R35). Ready for any flooring type.
Installs on the same structural frame — no demolition required.
Acrylic, insulated, hybrid, and SIP panel options matched to your sun exposure and OKC climate conditions.
Four distinct seasonal problems. One custom sunroom installation solves all of them.
OKC averages more than 50 days above 95 degrees every summer. A well-specified sunroom with the right roof and wall insulation keeps the interior temperature comfortable without requiring a dedicated HVAC system running at full load.
April and May bring fast-moving thunderstorms, damaging hail, and tornado-watch conditions. A fully enclosed sunroom with a structural aluminum frame handles ordinary severe weather without the furniture-scrambling panic that goes with an open porch.
Oklahoma sits among the highest UV-index states in the country. ViewFlex vinyl and Low-E glass options reduce UV transmission into the space, protecting furniture, flooring, and skin without blocking the natural light that makes a sunroom worth having.
Mosquitoes, flies, and cicadas are a fact of outdoor life in OKC from late April through October. Every sunroom model includes a fully enclosed perimeter that keeps insects completely outside, with ventilation options that still let the Oklahoma breeze in when conditions are pleasant.
Every model is custom-manufactured to your exact dimensions and installed by factory-trained certified master builders. Click any model below to explore its full specifications.
The Sunspace Model 200 WeatherMaster Sunroom, their most popular product, is ideal for upgrading from a screen room. It features 2-inch foam panels and aluminum extrusions, incorporating the WeatherMaster 4-Track Vinyl Window System. Panels slide easily to open up to 75% for air or close completely for protection from rain, wind, and insects. Available in various wall/frame colors and four ViewFlex vinyl tints, the Model 200 naturally complements your OKC home’s exterior.

Oklahoma homeowners who want a structurally refined 3-season sunroom with the clarity and permanence of single-glazed glass windows rather than vinyl panels.
The Model 300 uses Sunspace’s 2-inch extruded insulated aluminum pillars paired with single-glazed glass windows for a sunroom that feels like a permanent architectural addition to the home. Both sashes on every window operate independently with no fixed side, giving the room a cross-breeze quality that vinyl panel systems cannot replicate.

Aluminum-framed double roller design — both sashes operate with no fixed side, allowing ventilation from both directions.

Three thickness options from R17 to R35 — pre-manufactured insulated deck ready for any finish flooring.
Goes over an existing deck, porch, or carport without requiring a new foundation in most cases.
Aluminum construction requires no painting, sealing, or annual treatment — season after season.
Oklahoma homeowners who want a true living space addition that functions comfortably in every season, including Oklahoma winters and full summer heat.
The Model 400 is Sunspace’s full 4-season sunroom, built to a structural and thermal standard that makes it a genuine room addition rather than a 3-season enclosure. High-density 3-inch foam walls with 3-inch aluminum extrusions handle Oklahoma wind and snow loads. Commercial-grade thermal breaks in every extrusion eliminate condensation and heat loss at the frame level — a detail that budget sunroom systems completely ignore.

Functions with your existing home heating and cooling system. No dedicated HVAC unit required.
The right model comes down to two questions: how many seasons do you want to use the space, and what level of climate control do you need?
Most Oklahoma homeowners choose between the Model 200 and Model 400. The Model 200 solves insects, weather, and moderate heat. The Model 400 adds full winter warmth and commercial-grade thermal performance for a room that functions like the rest of the house. Not sure which fits your porch and your goals?

From your first call to the day you’re relaxing in your new space, here’s exactly what to expect when you work with Sunspace by Express Sunrooms.
We visit your Oklahoma home, evaluate your porch or patio, and discuss which sunroom model fits your goals and your budget. No pressure. No commitment. Just a professional assessment and an honest recommendation.
We design the sunroom to your exact dimensions and specify the right model, roof, colors, and any functional enhancements. The price we quote is the price you pay — not a penny more, regardless of what arises during the project.
We handle the permitting process and pay for permits, engineering, and materials upfront. Your sunroom components are custom-built in a temperature-controlled Sunspace facility to your exact specifications.
Factory-trained certified master builders arrive on time, install with precision, and clean up completely. No sawdust. No lingering crew. A finished result that looks like it was always part of your OKC home.
We walk you through the finished sunroom and confirm every detail. Then you pay. That is the No-Risk, No-Pay Guarantee that no other sunroom installer in Oklahoma offers.
We cover permits, engineering, and materials before you commit a dollar. You pay only when the sunroom is complete and you are fully satisfied. No other sunroom installer in Oklahoma works this way.
Our installers complete special factory training on every Sunspace product we install. When you hire us, you get a certified expert in the specific sunroom system being built — not a generalist contractor.
The quoted price never changes. Every installation carries a two-year no-questions-asked labor warranty. The transferable lifetime warranty stays with your home and can be passed to a new buyer if you sell.
Sunspace by Express Sunrooms of Oklahoma installs custom sunrooms across the entire state. Our service area includes the Oklahoma City and Tulsa metros, as well as premier communities and neighborhoods across the state.
A 3-season sunroom (Model 200 or Model 300) is designed for comfortable use in spring, summer, and fall. It provides full weather and insect protection but is not insulated or sealed to the level required for comfortable winter use without supplemental heating. A 4-season sunroom (Model 400) uses 3-inch foam walls, commercial-grade thermal breaks, and Low-E Argon gas glass to create a room that functions comfortably in all four seasons with your existing home heating and cooling system.
