Model 200 WeatherMaster Sunroom: Sunspace's Most Popular 3-Season Sunroom, Explained
The Sunspace Model 200 is a 3-season sunroom with WeatherMaster vinyl windows that open up to 75%, turning your deck or porch into a bug-free room from spring through fall. It is Sunspace's most popular sunroom — and once you see how its window system works, it is easy to understand why.
If you love eating outside but hate the mosquitoes, the sudden rain shower in the middle of dinner, or the wind that ends the evening early, a 3-season sunroom is built for exactly that problem. The Model 200 WeatherMaster Sunroom combines the open-air feeling of a screen room with the protection of an enclosed porch, in a room that is custom designed and manufactured for your home.
What exactly is the Model 200?
The Model 200 is a modular 3-season sunroom. Its walls are built with 2-inch foam panels and aluminum extrusions, and most of each wall is window — specifically, the WeatherMaster Vertical 4-Track Vinyl Window System, exclusive to Sunspace. The room is made to measure: it can be installed directly onto an existing deck or patio, under an existing roof, or used to convert a porch you already have into a real living space.
That last point matters. Many homeowners do not need a full home addition.
They already have the space — a deck that is too buggy in July, a porch that is too cold in May. The Model 200 encloses that space and makes it usable for most of the year, without the cost and disruption of conventional construction.
The window system that makes it different
Most sunrooms are defined by their windows, and the Model 200 is no exception. Each WeatherMaster window has four vinyl panels that slide effortlessly on vertical tracks.
You can stack them at the top, stack them at the bottom, or bunch them in the middle — the opening is infinitely adjustable, up to 75% ventilation. On a warm evening, the room feels like a screen room. When the weather turns, the panels close and keep out rain, wind, pollen and harmful UV rays.
The panels are glazed with ViewFlex vinyl instead of glass. ViewFlex is more durable than glass — it flexes instead of shattering, which homeowners with kids, pets and hockey sticks nearby tend to appreciate — and it is available in four tints: clear, smoke grey, dark grey and bronze, so you control how much sunlight enters the room. The system is part of the broader family of WeatherMaster window and door systems, which Sunspace describes as North America's #1 porch and sunroom window.
Which seasons can you actually use it in?
As the name says: spring, summer and fall. A 3-season sunroom is designed to extend your outdoor season on both ends — coffee outside in April, dinner outside in October — while providing full protection from insects and weather all summer long. It is not a fully insulated four-season room, and it is not heated like the rest of your house; on the coldest winter days, it rests, like your deck does.
If year-round, heated living space is what you need, look at Sunspace's insulated Model 400 instead. And if you prefer real glass over vinyl, the Model 300 3-season glass sunroom is the glass alternative in the same 3-season category. You can compare all Sunspace sunroom models side by side — Model 100 screen room, Model 200, Model 300 and Model 400 — before deciding.
Vinyl or glass: why so many homeowners choose vinyl
Homeowners comparing the Model 200 and the Model 300 usually land on three differences. First, ventilation: the Model 200's 4-track panels open up to 75% of the window area, far more than a typical sliding glass window, so the room breathes like a screen room. Second, durability: ViewFlex vinyl will not shatter, and the panels are lightweight and easy to slide for everyone in the family. Third, flexibility: the panels can be positioned anywhere along the track, so you open the top on a breezy day and the bottom when the dog wants to watch the yard.
Colors and tints that match your home
A sunroom should look like it was always part of the house. The Model 200's wall and window frames come in five standard colors — white, black, driftwood, bronze and grey — and the ViewFlex vinyl comes in the four tints listed above. Your local dealer designs the room with you, so the finished sunroom matches your home or cottage exterior rather than looking added on.
Is the Model 200 right for you?
The Model 200 is usually the right answer if:
- You have a deck, patio or porch that insects, rain or wind keep cutting short;
- You want a room you can use from spring through fall, not a full four-season addition;
- You want maximum fresh air — up to 75% ventilation — with full weather protection when you need it;
- You prefer low-maintenance, durable vinyl windows over glass;
- You want the project custom built and professionally installed by a local dealer.
Frequently asked questions
Is the Model 200 a four-season sunroom?
No. The Model 200 is a 3-season sunroom, designed for spring, summer and fall use. For a fully insulated room you can heat all winter, consider the Sunspace Model 400.
Can a Model 200 be installed on my existing deck or porch?
Yes. Sunspace sunrooms are modular units, custom designed for your home, and can be installed directly onto an existing patio or deck, under a previously constructed roof, or as a porch conversion.
How much ventilation do WeatherMaster windows provide?
Up to 75%. The four vinyl panels in each window slide up, down, or stack in the middle, so you can adjust the opening to the weather — from fully closed against rain and pollen to wide open on a summer evening.
Are vinyl windows durable enough for a sunroom?
ViewFlex vinyl glazing is more durable than glass and will not shatter. It is available in clear, smoke grey, dark grey and bronze tints, and the window system is virtually maintenance free.
