Summer is a glorious time in Wisconsin’s Northwoods and Michigan’s Upper Penninsula—but the season is gone in a few short months. Extend your summer by adding a three-season room to your house or cottage. The Model 300, 3 Season Sunroom by Sunspace can be installed right on your patio or deck, literally building on the space you love so that you can enjoy it in the spring and fall as well. Select a roof system that’s right for you, such as a cathedral ceiling or a contemporary studio pitch roof, or build under an existing roof. You can even turn your carport into an enclosed leisure room. The options are wide open! We custom-design our sunrooms to fit with your home and install them, worry-free.

The Model 300 is a bright, classy addition to any house or cottage. Increase your living space and get the most of your backyard, rain or shine, with an open, airy sunroom. Whether you are seeking a space to entertain friends and family, a playroom for the kids or grand kids, or a cozy green space all your own, a 3 Season Sunroom is a perfect place to relax. Aluminum framed, double roller windows provide ventilation out of both sides of the window. Both sashes operate, giving you maximum flexibility to catch summer breezes without letting in the bugs, rain, and UV rays that used to drive you indoors.

Sunspace 3 Season Sunrooms are durable and virtually maintenance free. Two-inch extruded insulated aluminum pillars with single glazed glass, high density foam panels, and two-inch aluminum extrusions extend the seasonal life of your new favorite room that much longer. An integrated gutter system keeps rain away from your home’s foundation. Roof projection, snow load, and R-Value are always considered when we customize your roof. Select among White, Driftwood, Bronze, Black or Grey for the color that will fit best with your exterior.



  • Choose from 3", 4" or 6" thicknesses
  • Roof projection, snow load & R-Value are always considered in the customization of your roof system
  • All systems constructed of high density foam core
  • Laminated with aluminum skins on both sides
