Your Covered Porch Should Do More Than Collect Leaves
A covered porch already has the most important component in place: a roof. What most St. Louis Metro Area porches lack is the wall system that turns a breezy, insect-filled, weather-exposed platform into a space the family chooses over the living room on a comfortable evening. Missouri mosquitoes, spring pollen, summer heat, and fall wind all shorten the time an open porch is usable. A properly installed enclosure system removes those limitations without requiring a full room addition or structural rebuild.
Sunspace porch enclosure systems are custom-fabricated to fit your specific opening, your existing roof structure, and your knee wall height. The result looks like it was always part of the home because the components are sized and built around what is already there.
More Months of Genuine Use
An enclosed porch extends the comfortable outdoor season from early spring through late fall and, depending on the system chosen, into the cooler Missouri months that typically make open porches unusable.
Weather and Insect Control Together
Wind, rain, pollen, and insects are all managed by the enclosure wall system simultaneously. Closing the panels takes seconds and keeps the space comfortable through whatever Missouri weather decides to do.
A Finished Space That Adds Home Value
A permitted, professionally installed porch enclosure adds a usable, finished room to the home’s functional square footage without the disruption and cost of a full structural addition.
An Upgrade Path Already Built In
WeatherMaster enclosures can grow with your needs. A 2-season or 3-season configuration today does not lock the space into that level permanently. The system is designed to evolve.
Three Enclosure Approaches. One Authorized St. Louis Metro Area Installer.
Every porch enclosure project begins with a conversation about your existing structure, how your household plans to use the space, and how much weather protection the room needs to deliver. Sunspace offers three distinct wall system approaches, each suited to a different priority set.
Adjustable Weather Protection That Keeps the Porch Feeling Open
The WeatherMaster vinyl enclosure system is the most versatile starting point for St. Louis Metro Area porch conversions. ViewFlex vinyl panels adjust from fully open to completely closed, giving your household control over airflow, weather exposure, and bug protection without committing the porch to a fixed enclosed state. The system works with the Vertical 4-Track configuration for up to 75 percent ventilation, or the Horizontal 2-Track for a cleaner slider aesthetic with 50 percent ventilation. Both systems are custom-fabricated to fit your exact porch opening and are designed to reduce the need for special trade installation, which keeps the project cost-effective without sacrificing finish quality.
Features & Benefits
- Vertical 4-Track ventilation up to 75 percent Panels stack up, down, or center so airflow can be adjusted precisely based on conditions and personal preference.
- Horizontal 2-Track ventilation up to 50 percent Left-to-right slider operation for a clean, simple enclosure that handles Missouri wind and rain effectively.
- ViewFlex vinyl glazing More impact-resistant than glass, virtually maintenance-free, and proven in residential porch applications for over forty years.
- Four tint options Clear, Smoke Gray, Dark Gray, and Bronze to manage light, heat, and privacy across different porch orientations.
- Integrated fiberglass mesh screen Keeps insects out when panels are open during Missouri’s active warm-weather months.
- Extruded aluminum frames Structural aluminum construction that holds panel weight and dimensional shape through Missouri’s seasonal temperature swings.
- Five frame color options White, Driftwood, Bronze, Black, and Gray for a clean match to your home’s existing exterior finish.
- Custom fabricated to your opening Every panel is sized to your specific porch width, height, and knee wall dimensions rather than adapted from a standard size.
- Upgrade-ready configuration The WeatherMaster frame accepts future improvements, including additional enclosure components when your needs grow.

EXPERT INSIGHT
WeatherMaster is the right answer for most St. Louis Metro Area porch enclosures because Missouri weather demands flexibility rather than a fixed position. The ability to open the porch fully on a perfect April evening and seal it against a July thunderstorm in under a minute is the core reason this system is the most commonly specified enclosure for existing covered porches.
Maximum Light, Maximum Clarity, A Room-Like Finished Look
When the priority is a glass-forward porch enclosure that looks and feels like a proper room addition from both inside and outside the home, full glass panels deliver that outcome more completely than vinyl. The Sunspace full glass system uses single-glazed glass panels in an extruded aluminum frame structure, custom-fabricated to the dimensions of your existing porch. Natural light comes through without filtering or tinting, views stay clear and unobstructed, and the finished enclosure reads architecturally as a deliberate and permanent part of the home. For St. Louis Metro Area homeowners who want the space to have a glass-forward quality that vinyl cannot replicate, this system is the more resolved option.
Features & Benefits
- Single-glazed glass panels Maximum natural light transmission and completely clear, unobstructed views of the yard and surrounding landscape.
- Extruded aluminum frame structure Structural integrity and dimensional stability in an aluminum system that holds its shape through Missouri’s freeze-thaw cycles and summer heat.
- Custom fabricated to your porch Every panel is sized precisely to the existing opening, roof pitch, and knee wall height of your specific porch structure.
- Double-roller window operation Both sashes open independently for ventilation from both sides of each window unit without a fixed side limiting airflow.
- Multiple frame color options White, Black, Driftwood, Bronze, and Gray to coordinate with the home’s existing exterior finish and architectural style.
- Reduces wind, rain, and seasonal temperature intrusion Closed glass panels create a solid weather barrier while maintaining the visual connection to the outdoor space.
- Architectural finished quality The completed enclosure looks like a permanent room addition rather than a product installed into an existing opening.

EXPERT INSIGHT
A full glass is the right choice when the homeowner cares as much about how the enclosure looks from the yard as how it performs from inside. The glass-forward finish quality reads at a higher level than vinyl, and the double-roller operation provides effective seasonal ventilation without the adjustability mechanics of the WeatherMaster track system.
Close In the Space Beneath an Existing Roof or Elevated Deck
The Walls Under system addresses a specific and common St. Louis Metro Area porch situation: a raised deck, elevated porch, or under-porch space that has a roof above it but open air on the sides and below. Rather than building an entirely new structure, the Walls Under system fills those open openings with custom-fabricated WeatherMaster or full glass panels that turn the underutilized space into a functional, protected room. The system is custom-fabricated to fit the specific geometry of your existing structure and significantly reduces the need for complex trade installation compared to conventional enclosure construction methods.
Features & Benefits
- Custom fabricated to your opening geometry Panels are built to the exact dimensions of your raised porch, under-deck, or elevated structure rather than forcing standard sizes into a non-standard space.
- WeatherMaster or full glass panel options Choose adjustable vinyl ventilation panels or clear single-glazed glass, depending on how much airflow flexibility versus visual clarity matters most for your space.
- Stylish, modern finished appearance The completed wall system combines a contemporary panel aesthetic with easily installed custom-fitted components that look deliberate rather than improvised.
- Reduces the need for special trade installation The Sunspace Walls Under system is engineered for efficient installation, which keeps the project timeline and cost more predictable than conventional enclosure construction.
- Converts underused space into a livable area Transforms an elevated porch underside, raised deck perimeter, or open under-porch zone into a space the household uses regularly.
- Extruded aluminum frame construction Structural aluminum holds panel alignment and dimensional accuracy through Missouri’s seasonal temperature and humidity range.
- Creates an ideal living area The finished Walls Under enclosure becomes a space families genuinely choose to spend time in, rather than an afterthought attached to the rear of the home.

Best for St. Louis Metro Area homeowners with elevated decks, raised porches, or under-porch spaces that already have overhead coverage but need enclosed walls to become genuinely usable rooms.
EXPERT INSIGHT
The Walls Under system is often the most overlooked porch enclosure option and frequently the most practical one for homes with a raised deck or elevated porch structure. The space already has a roof. The only thing separating it from a comfortable enclosed room is a properly fitted wall system, and that is exactly what this product provides.

Why St. Louis Metro Area Homeowners Trust Sunspace USA for Porch Enclosures
Enclosing a porch requires more than filling an opening with panels. It requires understanding the existing structure, the local building requirements, and the household priorities that determine which system performs best for that specific home.
Genuine Sunspace Products, Factory Fabricated
Every enclosure panel we install is custom-manufactured by Sunspace to the confirmed dimensions of your porch. There are no standard-size panels adapted to fit and no aftermarket components substituted into the system.
Specified for Missouri Conditions
Missouri porch enclosures deal with summer heat, spring pollen, seasonal humidity, and temperature swings between day and night that affect both product selection and installation method. Our recommendations account for those conditions from the first site visit.
Custom Fit Around Your Existing Structure
Every porch presents a different combination of roof pitch, knee wall height, opening width, and structural condition. We size the system around what is actually there rather than designing around a generic template.
Upgrade Paths That Stay Open
A WeatherMaster enclosure installed today does not prevent a more complete enclosure later. The system is designed to accept future improvements, so your initial investment moves forward rather than being replaced.
One Team Across Every Phase
A single local crew handles the site assessment, product specification, permit coordination, and installation from the first conversation through the final walkthrough with no subcontractors and no handoffs.
Full Outdoor Living Coordination
When the enclosure project connects to a deck, railing, patio cover, or privacy wall need, we coordinate all of it so the finished outdoor space holds together as one complete and coherent design.
Our Porch Enclosure Installation Process in St. Louis Metro Area
Every project follows a clear four-step path so the finished enclosure fits the porch, the home, and the way your household plans to use the space.
01
Site Assessment
We visit the property, measure the porch opening, evaluate the existing roof structure, knee wall condition, and framing, and talk through how the household wants the enclosed space to function before any system is proposed.
02
System Selection
Based on your porch structure, ventilation priorities, aesthetic preferences, and future upgrade plans, we help you choose between WeatherMaster vinyl, full glass, or Walls Under panels and confirm every specification before fabrication begins.
03
Custom Fabrication
Your enclosure panels are manufactured by Sunspace to the exact dimensions confirmed during the site assessment. Every component arrives sized for your specific porch rather than trimmed to fit on installation day.
04
Installation and Walkthrough
Our team installs each panel cleanly and precisely, then walks the finished enclosure with you before closing out the project to confirm every panel operates correctly and the space meets your expectations completely.
Questions About Porch Enclosure Installation in St. Louis Metro Area
These are the questions we hear most often from homeowners considering porch enclosures across the greater St. Louis and eastern Missouri region.
WeatherMaster uses ViewFlex vinyl panels that adjust from open to closed for flexible daily ventilation control and four tint options. Full glass uses single-glazed clear glass panels for maximum light, clear views, and a more architectural finished appearance. WeatherMaster is the more adaptable daily-use system. Full glass is the right choice when visual clarity and a glass-room aesthetic are the primary goals.
In most cases, yes. Sunspace porch enclosure systems are custom-fabricated to fit the existing roof structure, knee wall, and opening dimensions of a covered porch without requiring significant structural modification. We assess the existing conditions during the site visit and identify any preparation work needed before fabrication begins.
Walls Under is a Sunspace enclosure system designed specifically for raised decks, elevated porches, and under-porch spaces that already have overhead coverage but have open sides. Custom-fabricated WeatherMaster or full glass panels fill those openings and turn the underutilized structure into a protected, livable space without rebuilding the entire area from the ground up.
Yes. The WeatherMaster frame and extrusion system is designed with upgrade compatibility in mind. A 2-season or 3-season WeatherMaster enclosure can be evolved toward a more complete configuration at a later stage without requiring the existing structure to be removed and replaced.
In most Missouri counties and municipalities, yes. Any enclosure that adds wall systems to an existing porch typically requires a building permit and a plan review. We manage the permit application process on your behalf and coordinate directly with the local building department so you do not have to navigate that process independently.
Yes. Porch enclosure projects regularly coordinate with railing installation, patio cover work, or deck improvements when those elements are part of the same outdoor space. We coordinate all of it through a single project scope so every component fits together properly.
Most porch enclosure installations are completed within a few days of on-site work once panels are fabricated and delivered. The total timeline from site visit to completion typically runs six to ten weeks, depending on the enclosure system selected, local permit processing time, and scheduling. We provide a realistic timeline during the site assessment and keep you informed at every stage.
