Your porch, with more possibilities
The Mattison Weather Breaker Wall starts with a screen porch and adds specialty windows with sliding, flexible vinyl panels. We use selected systems from Sunspace and Porch Conversions, fitting the tracks, screens, doors and trim to your space.
Use it through three seasons, or enjoy it throughout the year when your climate and comfort expectations allow. The weather-blocking windows are not energy-efficient insulated glass: heating or cooling the porch can require substantially more energy, and extreme temperatures will affect comfort. For a room designed around efficient year-round conditioning, compare our insulated All Season Rooms.

A few things to know
Yes, depending on your climate, the weather and your comfort expectations. Think of it as a screen porch with added wind and weather protection. The flexible vinyl windows are not energy-efficient insulated glass. Heating or cooling this space can use substantially more energy than an insulated all-season sunroom, and comfortable temperatures are not guaranteed in extreme weather.
Often, yes. We first inspect the roof, framing, floor, attachment points and drainage. Your proposal identifies any repairs or structural work needed before the enclosure goes in.
These specialty porch windows combine flexible vinyl glazing with insect screens. If you want insulated glass and heating and cooling designed for year-round use, ask about our All Season Rooms.
It depends on the panel arrangement. Sunspace WeatherMaster four-track windows offer up to 75% ventilation. We confirm the opening area for the specific product in your proposal rather than applying one percentage to every system.
Common choices include white, black and bronze frames, with clear and tinted vinyl. Additional colors and screen options vary between Sunspace and Porch Conversions. We review the available samples with you.
Follow the care guide for your selected manufacturer. Use approved cleaners and soft cloths on flexible vinyl; avoid abrasive cleaning and ammonia. We explain panel operation and cleaning at project handoff.
Product coverage depends on the manufacturer and components selected. Your project documents identify the product warranty and installation coverage, including their terms and exclusions.
