Best For: Maximum ventilation, insect and UV protection, open-air feel with full seasonal comfort
The Model 200 WeatherMaster Sunroom is the most versatile porch enclosure in the Sunspace lineup and the most popular choice for homeowners who want to keep the open-air feeling of their existing deck while gaining complete protection from bugs, rain, and harmful UV rays.

MODEL 300 — Glass Window 3-Season Sunroom
Season: May through October
Best For: Glass clarity, unobstructed views, upscale appearance, spring through fall living
The Model 300 3-Season Sunroom is a bright, refined addition to any home. Where the Model 200 uses vinyl windows, the Model 300 uses aluminum-framed single-glazed glass with 2-inch extruded insulated aluminum pillars. For homeowners who face a pool, a landscaped yard, or a waterfront view, the Model 300 delivers unobstructed sightlines that vinyl windows cannot match.
✦ 2-inch extruded insulated aluminum pillars with single-glazed glass: bright, refined, virtually maintenance-free
✦ Double roller windows: ventilation from both sides of every opening, both sashes operate independently
✦ Fully unobstructed sightlines: glass clarity preserves views of yards, pools, and landscapes
✦ Roof options: cathedral ceiling or contemporary studio pitch to match your home’s architectural style
✦ 4-inch or 6-inch roof thickness options: snow load and R-Value factored into every design
✦ Integrated aluminum gutters and fascia: heavy-duty, extruded, worry-free water management
✦ Installs over existing structures: deck, porch, or carport without a complete structural rebuild in most cases

MODEL 400 — All-Season Insulated Sunroom
Season: Year-Round
Best For: Year-round comfortable use, full HVAC integration, true room addition with maximum thermal performance
The Model 400 All-Season Sunroom is designed for homeowners who want a true year-round room addition. High-density 3-inch foam walls, commercial-grade thermal breaks, and high-efficiency Low-E Argon glass maintain comfortable temperatures in every New England season, including the months when a 3-season sunroom is no longer usable. Every aluminum extrusion has a commercial-grade thermal break that reduces condensation and heat loss at the frame.
✦ High-density 3-inch foam walls: warmth and comfort in every season, including January and February
✦ Commercial-grade thermal breaks on all extrusions: reduces condensation and heat loss at the frame level
✦ High-efficiency Low-E Argon glass: superior insulation and UV control on all windows
✦ Designed for full HVAC integration: consistent year-round climate control through your home’s existing system
✦ ThermaDeck insulated floor system: R-19, R-28, or R-35, ready for carpet, tile, laminate, or hardwood
✦ Heavy-gauge 3-inch aluminum extrusions: strong structural support against wind and New England snow loads

What a Custom Sunroom Installation Adds Your Home
A Room You Actually Use:
A well-designed sunroom becomes the most-used room in the house during the warm season: morning coffee, dinner guests, kids at play, evenings winding down.
Months of Comfort:
A Model 200 or 300 extends your usable outdoor season from three months to six or seven. A Model 400 extends that to twelve, making the sunroom a true year-round addition.
Protection Without Isolation:
Sunspace sunrooms protect you from insects, UV, rain, and wind without closing off the view of your yard. You stay connected to the outdoors while staying completely comfortable.
Factory-Certified Installation:
Every installation is handled by factory-certified Sunspace professionals. Precision construction and clean finishing details on every project, every time.
No Sawdust, No Disruption:
Your sunroom is custom-manufactured off-site and installed with minimal disruption. No weeks of on-site construction, no sawdust, no long-term contractor presence.
Lasting Property Value:
A custom sunroom installation is consistently one of the highest-return home improvements in the Northeast, adding both lifestyle and measurable property value.

Frequently Asked Questions
Sunroom Installation FAQs
What is the difference between a 3-season and a 4-season sunroom?
A 3-season sunroom uses vinyl or glass windows without full thermal insulation in the walls or frame. It is comfortable from late spring through early fall, typically May through October. A 4-season sunroom like the Model 400 uses high-density 3-inch foam walls, commercial-grade thermal breaks at every aluminum extrusion, and Low-E Argon glass for year-round comfort, including winters. The Model 400 is also designed to integrate with your home’s HVAC system.
How do I choose between the Model 200 and Model 300?
Choose the Model 200 WeatherMaster Sunroom if maximum ventilation and the open-air feeling of your existing porch are the priority. Its ViewFlex vinyl windows stack and adjust to any position, and the four tint options give you control over glare and heat on summer afternoons. Choose the Model 300 Glass Sunroom if you want glass clarity and unobstructed views of your yard, pool, or landscape. The aluminum-framed glass panels give the room a traditional windowed-room appearance that some homeowners prefer for its aesthetic refinement.
Can a sunroom be added to an existing porch or deck?
Yes. All three Sunspace sunroom models can be installed on an existing covered porch, over a deck surface, or under a previously constructed roof. During the free in-home consultation, we evaluate your existing structure to confirm attachment points and specify the right approach for your space.
How long does sunroom installation take?
Because every Sunspace sunroom is custom-manufactured off-site in a climate-controlled facility, the on-site installation is precise and fast, typically completed in one to two days depending on project size and complexity. There is no extended on-site construction, no sawdust, and no weeks of disruption to your property or schedule.
What is ThermaDeck, and do I need it?
ThermaDeck is a pre-manufactured insulated floor system paired with the Model 400. It uses Engineered Oriented Strand Board sheets sandwiching an insulating core, available at R-19, R-28, or R-35. It eliminates the framing and subfloor labor that traditional room additions require, and arrives ready to receive carpet, tile, laminate, or hardwood. It is the right choice for a truly year-round room with a finished floor that performs as well as the insulated walls around it.
Can I start with a screen room and upgrade to a sunroom later?
Yes. The Sunspace Model 100 Screen Room is specifically engineered to upgrade directly to the Model 200 WeatherMaster sunroom at any time using the same structural framework. Many homeowners start with a screen room during one season and upgrade to the WeatherMaster enclosure when they are ready for full weather protection.
Can I add a bifold door system to my sunroom?
Yes. Bifold door systems can be incorporated into any sunroom installation to create a wide-opening folding entry that stacks fully into the frame when open. This is a popular upgrade for Model 200 and Model 300 installations where a large unobstructed opening is desired.
Do you install sunrooms for commercial properties?
Yes. Our commercial sunroom and porch enclosure service covers restaurants, hospitality properties, and multi-unit residential buildings across Connecticut. Commercial projects follow the same factory-certified installation process as residential work.
What railing options are available for my sunroom?
Sunspace offers an integrated structural aluminum alloy railing system with no visible fasteners, available with a glass kick plate or as a standard integrated railing. It meets code heights of 36 inches and 42 inches, with custom heights for elevated deck applications. We also install standalone aluminum railing systems for decks and porches.
Do you also install patio covers or privacy screens as part of a sunroom project?
Yes. Many homeowners combine a sunroom installation with an adjacent patio cover or privacy wall system to complete the outdoor living zone. Both can be designed and quoted at the same time as your sunroom for seamless coordination.
