If you live in Connecticut, Massachusetts, or Rhode Island, you already know how much comfort, sunlight, and value a sunroom can bring to your home. But choosing the right Sunspace Sunroom Model—whether for a porch conversion or a brand-new build—can feel overwhelming at first. That’s why professional Sunroom Installation is essential to ensure your space is designed and built perfectly for your needs.
The key is to match your design to your lifestyle, climate, and budget—not just the price tag. In New England, that also means thinking about insulation, snow loads, and seasonal comfort.
In this guide, we’ll break down the four main Sunspace models—100, 200, 300, and 400—comparing airflow, insulation, glass options, and structure. You’ll also get a practical framework for choosing the model that best fits how you live and use your space.
Sunspace Models at a Glance
| Model | Best For | Wall / Window System | Insulation Level |
| Model 100 | Bug-free outdoor living, spring through fall | Aluminum framing with durable screens (upgradeable to Model 200) | None — focused on airflow and openness |
| Model 200 | Extended 3-season comfort with airflow control | WeatherMaster™ Vertical 4-Track vinyl windows with ViewFlex vinyl glazing | Minimal — comfort boost over screens |
| Model 300 | Bright 3-season glass rooms | Single-glazed glass windows in 2″ extruded aluminum pillars | Low — weather protection without thermal walls |
| Model 400 | True 4-season sunrooms for year-round use | Insulated walls, thermally broken aluminum, and Low-E Argon glass | High — engineered for cold winters and snow load |
Model 100 — Screen Room Simplicity
Model 100 is the classic screen room—perfect for homeowners who love the breeze but not the bugs. It’s a durable, low-maintenance choice for porches, decks, or lakeside lots where airflow matters most.
- Structure: All-aluminum framing with heavy-duty screens
- Seasonality: Ideal from spring through fall
- Upgrade Path: Can easily transition to Model 200 later without rebuilding
It’s the most budget-friendly way to start enjoying outdoor living, and the clean design integrates easily with any home style.
Model 200 — WeatherMaster® Ventilation and Flexibility
The Model 200 introduces the signature WeatherMaster® Vertical 4-Track System, which lets you open up to 75% of your wall space for fresh air.
- Windows: ViewFlex™ vinyl glazing that resists UV damage and impact
- Options: Multiple tint levels for privacy and glare control
- Comfort: Excellent airflow when open; solid protection when closed
In New England, this model stretches your outdoor season deep into spring and fall, keeping out rain, wind, and insects while maintaining a porch-like feel. It’s a top pick for porch conversions and budget-conscious comfort.
Model 300 — Glass Clarity for Three Seasons
The Model 300 upgrades your experience with single-glazed glass and stronger framing for a polished, open look.
- Framing: 2″ extruded aluminum pillars with dual-roller glass sashes
- Look: Bright, modern aesthetic with clear views
- Roof Options: Compatible with cathedral or studio profiles
This model provides more weather protection than vinyl windows but stops short of full insulation. Choose it if you want a bright, glass-walled space for spring, summer, and fall without the cost of full thermal performance.
Model 400 — Insulated Comfort, All Year Long
If you want a true four-season room, Model 400 delivers.
- Walls: High-density foam insulation with thermally broken aluminum extrusions
- Glass: High-efficiency Low-E Argon windows for energy savings
- Performance: Engineered for snow loads, wind, and New England winters
This model meets or exceeds 2018 Connecticut State Building Code requirements for structural and energy performance. It’s ideal for home offices, dining areas, or family rooms that stay comfortable year-round.
If you plan to heat or cool your space, start your comparison here—it’s the closest match to a traditional home addition.
How to Choose the Right Sunroom Model for New England
- Start with how you’ll use the space
-
- Occasional relaxing and entertaining → Model 100 or 200
- Extended seasonal living → Model 300
- Year-round comfort → Model 400
-
- Consider your home’s structure and climate
-
- For coastal areas or high humidity: prioritize corrosion-resistant framing and proper ventilation.
- For inland or snowy areas: prioritize insulation and load-rated roofs.
-
- Plan for the future
-
- Model 100 can be upgraded to 200 later.
- Model 300 to 400 transitions require full structural upgrades due to insulation and thermal requirements.
-
Maintenance and Longevity
All Sunspace models use aluminum framing and ViewFlex vinyl glazing designed for long-term durability.
- Cleaning: Use mild soap and soft cloths—no abrasives.
- Vinyl Tint Options: Reduce UV exposure and glare over time.
- Upgrade Ease: Model 100 to 200 conversions reuse framing footprints.
These materials stand up to New England’s coastal moisture and inland temperature swings, keeping your investment beautiful and functional for decades.

Frequently Asked Questions About Sunspace Sunrooms in New England
1. Can I upgrade from a Model 100 Screen Room to a Model 200 later?
Yes. Sunspace designs the Model 100 with an easy upgrade path to Model 200. Your existing screen framing can typically stay in place while WeatherMaster™ 4-Track vinyl windows are added. This lets you convert from a basic screen room to a 3-season enclosure without rebuilding the structure.
2. Do Sunspace sunrooms meet New England building codes?
Absolutely. Each Sunspace Model 300 and 400 can be engineered to meet or exceed Connecticut, Massachusetts, and Rhode Island building code requirements for wind, snow load, and energy performance. The Model 400 in particular includes thermally broken aluminum, insulated panels, and Low-E Argon glass, allowing it to qualify as a true four-season living space.
3. Which Sunspace model is best for cold weather?
For cold New England winters, the Model 400 is the top choice. It features high-density foam-insulated walls, thermal breaks, and energy-efficient glass that help retain heat and reduce condensation. It’s ideal for homeowners who want to use their sunroom year-round or connect it to their home’s HVAC system.
4. Can a Model 200 or 300 be used in winter?
These models are designed as three-season rooms, so while they provide excellent wind and rain protection, they are not fully insulated. You can extend comfort into late fall or early spring with portable heat sources, but for consistent winter use, the Model 400 is recommended.
5. What is the difference between WeatherMaster vinyl and glass windows?
WeatherMaster™ vinyl windows (used in Model 200) are made from ViewFlex™ vinyl glazing, which is flexible, impact-resistant, and available in several tints.
Glass windows (used in Model 300 and 400) offer a clearer view and greater rigidity, with single-glazed or insulated Low-E glass depending on the model.
6. How long does a Sunspace sunroom last?
With proper installation and care, Sunspace aluminum framing and vinyl systems can last decades. Aluminum resists corrosion, and ViewFlex™ vinyl stands up to UV rays and temperature swings typical of New England’s coastal and inland climates. Occasional cleaning and seasonal inspection are usually all that’s needed.
7. Can I match my sunroom to my home’s architecture?
Yes. Sunspace offers custom color options, roof styles (studio or cathedral), and railing systems that integrate seamlessly with colonial, cape, and contemporary homes across Connecticut, Massachusetts, and Rhode Island. Each project is tailored for both appearance and performance.
8. How do I start the design process?
You can schedule a consultation with Sunspace by Sunroom Designs New England to review design options, pricing, and code requirements for your town. After measuring dimensions of your porch or deck area, your dealer will recommend the most practical model for your space and lifestyle.
